FAQ for STIGA robot lawn mower

An autonomous robotic lawn mower is a cable-free smart appliance that automatically cuts and maintains lawns without physical boundary wires. It uses GNSS-RTK satellite guidance combined with predictive AGS technology and a 4G connection to map the garden with centimetre-level precision. The robot operates systematically, following pre-planned cutting routes and performing multiple short cycles per day to mulch the grass clippings back into the soil as natural fertiliser. It can manage gardens from small yards up to 14,000 m², operating quietly at under 59 dB(A).

AGS (Active Guidance System) is STIGA's technology that allows robot mowers to navigate without boundary wires by predicting and planning around GPS signal gaps. It works in three steps: first, it maps which satellite constellations are visible above the garden. Then it continuously assesses signal quality across the lawn, flagging weak areas. Finally, it uses that data to plan routes in advance, scheduling cuts only when and where a stable signal is guaranteed.

If the GPS signal is weak, a STIGA autonomous robot mower will automatically avoid that specific area. It is programmed to predict signal drops and will detour around dead zones rather than risk stopping dead in the middle of your lawn.

Robot mowers and reference stations communicate via wireless signals to achieve centimeter-level navigation precision. Standard systems use a local antenna in your garden that calculates atmospheric signal errors and transmits corrections to the mower in real time.

How STIGA optimizes this communication:
Instead of an antenna in your yard, STIGA mowers communicate via a built-in 4G network connected to a premium ground antenna infrastructure. The robot’s quad-band GNSS engine continuously triangulates data from all six satellite constellations, ensuring pinpoint accuracy even under dense tree canopies or near tall buildings.

STIGA autonomous robot mowers are powered by integrated ePower lithium-ion batteries, with capacity varying by model to match the size of the garden it is designed to cover. This battery technology is optimised for the frequent charge-discharge cycles of daily mowing: the robot completes its lawn in two cutting sessions per day, returning to the docking station to recharge between them. The lithium-ion chemistry ensures consistent power output across the full charge cycle, keeping cutting performance stable from the first pass to the last.

Night mowing is not recommended for robot lawn mowers, even though it is technically possible. Grass is naturally humid after sunset, and cutting wet blades tears the turf rather than mulching it cleanly, increasing the risk of fungal disease. It also disturbs nocturnal wildlife such as hedgehogs. The STIGA.GO App automatically suggests daytime cutting windows when the lawn is dry and wildlife activity is low.

Multiple daily mowing cycles act as an automatic fertilising system. By finely chopping clippings into natural mulch, the robot returns essential nutrients and moisture to the soil, creating a greener, healthier lawn. To maximise these benefits, schedule two daily cuts with a minimum 5-hour rest between them so the grass can heal and recover.

The STIGA.GO App suggests specific mowing times to protect the lawn from being cut when it is most vulnerable - early morning dew and late evening wildlife activity are the two main risk windows to avoid. The app recommends two daily slots, typically a morning and a late-afternoon session, with a minimum 5-hour gap between them so the grass can seal and recover before the next cut.

Robot mowers cut systematically, following precise cutting patterns rather than moving at random across the lawn. You can choose between multiple direction cutting programs, depending on your needs and taste. All zones of your garden will be mown regularly and accurately leaving no uncut areas, while carefully avoiding over-mowing by passing several times in the same area.

Robot mowers offer three systematic cutting patterns - parallel stripes, chessboard, and grid - selectable and combinable via the app. Each pattern slightly overlaps mowing paths to ensure no grass is missed and no wheel traces are left. Parallel stripes suit daily maintenance, chessboard creates a decorative sports-pitch effect, and grid provides the most thorough coverage across every angle of the lawn.

No, autonomous robot mowers do not collect grass. Instead, they perform continuous mulching, chopping the clippings into tiny particles that are scattered back onto the lawn. These particles decompose quickly, acting as an organic, nutrient-rich fertilizer for the soil.

Yes, robot mowers can be fully controlled via smartphone app, without the need for a physical remote. The STIGA.GO App, available for iOS and Android, provides complete control over all robot functions from anywhere with a mobile connection.

Key app capabilities include:

-Zone Management: Set customized cutting heights and priorities for up to 30 separate zones.
-Pattern Selection: Choose and rotate cutting styles (Parallel Stripes, Chessboard, Grid).
-Remote Monitoring: Track mowing progress, check robot status, and receive obstacle notifications in real time.

Robot mowers find their charging station using GPS coordinates recorded during the initial setup process. When the battery runs low or a mowing session is complete, the robot uses its GNSS-RTK navigation to return to the exact location of the docking station, without needing a guide wire or boundary cable.

During installation, the robot records the precise positions of both the charging station and the reference station. These two units can be installed in the same location or placed separately, depending on the layout of the garden, for example: if the charging station is best placed in shade while the reference station needs an open sky location for strong GPS reception.

Yes, autonomous robot mowers can safely cross paths, terraces, and paved areas to move between different cutting zones in your garden. To guarantee the safety of both the machine and your surfaces, the robot automatically disengages its blades while traversing these non-grass areas. Once it successfully reaches the new zone, the blades immediately re-engage to continue the mowing session without interruption.

Yes, STIGA autonomous robot mowers are equipped with a built-in anti-theft system managed via the STIGA.GO app. Once you enable the anti-theft geofence feature in the app settings, it protects your mower through three main security functions:

-Instant Alert: The app sends an immediate push notification to your smartphone if the mower is moved outside its virtual perimeter 

-GPS Tracking: You can monitor the real-time location of the robot mower to track its position at any time.

-Security Lock: The mower locks down digitally, making it completely unusable and impossible to re-register without your account authorization.

Connectivity is provided through STIGA’s cloud service via the 4G mobile network, integrated directly into the machine. STIGA partners with global cellular networks to ensure uninterrupted data flow between the mower, the STIGA Cloud, and the ground RTK antenna network, allowing the system to operate seamlessly without charging the user for local radio reference stations.

Robot mowers are manufactured in Castelfranco Veneto, Italy, where STIGA engineers designed and built the entire production line. The manufacturing process is kept fully in-house, allowing quality control at every stage of assembly.

"Yes, autonomous robot mowers are highly reliable and effective for continuous lawn maintenance. Their daily systematic cutting and mulching cycles drastically improve soil quality and grass density over time.

However, while they navigate virtual perimeters with high accuracy, a minimal amount of manual edge-trimming around complex obstacles or tight borders may still be required for a flawless finish."

To choose the right robot mower, you must evaluate three key factors:

-Garden size: Align your lawn's total area (m²) with the mower's maximum capacity.
-Complexity & slopes: Identify if your garden has steep inclines (up to 45°-50%) or narrow corridors that require advanced GNSS-RTK or AI vision guidance.
-Installation preference: Check if your garden layout is suited for wire-free virtual mapping via smartphone.

The robot mower range covers gardens from 400 m² to 14,000 m². Models from A 6v to A 8v are suitable for small gardens up to 800 m². A 10v to A 25v are designed for medium gardens up to 2,500 m², including slopes up to 45%. A 50v to A 140v cover larger lawns up to 14,000 m² with slopes up to 50%. Vista versions add an AI camera for obstacle detection and more precise cutting. All models share cable-free installation, GNSS-RTK navigation, AGS technology, and STIGA.GO app control.

The docking station must be placed on flat, sheltered ground near a power source, leaving a clear path for the mower to exit and return effortlessly.
The RTK reference station needs a clear view of the sky with at least 120° of open space above it to ensure a stable satellite connection. It can be installed either next to the docking station or mounted higher up on a wall or roof if trees or buildings block the signal.

For detailed step-by-step positioning rules, check the quick start guide inside the box or watch our STIGA Setup Tutorial on YouTube.

Setting and modifying your STIGA robot mower's virtual perimeter is done entirely through the STIGA.GO App no wires, no tools. You can update boundaries, add no-go zones, or adjust individual sections at any time, directly from your phone.

-To set the perimeter: Open the app, navigate to the Virtual Perimeter section, and follow the guided wizard to remotely drive the mower and map your lawn's outer boundary for the first time.
-To modify the perimeter: Open the app at any time, select the existing map, and adjust specific boundary points or add temporary exclusion zones (like a new flowerbed or garden furniture).

Yes,  STIGA robot mowers can manage from 2 up to 30 separate mowing zones depending on the model, all registered and controlled through the STIGA.GO App. Whether your garden areas are connected by a pathway or fully separated, there's a solution for both.

You can manage all activities of your STIGA autonomous robot mower through the STIGA.GO App on your smartphone. 
If you need to stop your robot lawn mower for an emergency, you can use the emergency STOP button you find on the robot's dashboard. Open the cover, push the red STOP button and the robot will immediately stop all ongoing operations and activities.

To keep your STIGA autonomous robot mower away from flowerbeds, bushes, and trees, you can use the STIGA.GO App to easily create digital ""No-Go Zones"" (or exclusion zones) and edit your virtual garden perimeter at any time.
Because the mower relies on advanced GPS-RTK technology and patented AGS navigation, it follows these virtual boundaries precisely without the need to lay any physical wires.

Yes, an active data connection is mandatory for STIGA autonomous robot mowers to function.

The robot relies on real-time RTK correction data transmitted via the STIGA Cloud to maintain centimetre-level GPS precision across the garden. Without this connection, the satellite positioning system cannot calculate corrected coordinates and the robot will not begin a new mowing session. However, if connectivity is temporarily interrupted mid-session, the robot will complete its current path using its onboard sensors and return safely to the docking station before attempting to reconnect.

The connectivity of STIGA autonomous robot mowers combine three connectivity layers to communicate with the STIGA Cloud and your smartphone:

-4G Mobile Network: The core system connection. It continuously syncs the robot with the cloud and satellite networks to receive RTK positioning corrections.

-Cloud Integration: Enables real-time remote communication, allowing you to control and monitor the mower via the STIGA.GO App from anywhere.

-Bluetooth: Used for short-range direct actions, such as initial smartphone pairing, manual remote driving, or adjusting hardware settings like the rain sensor.

Yes, STIGA autonomous robot mowers are fully compatible with Amazon Alexa. You can easily link your mower via the STIGA.GO App to integrate lawn care into your smart home ecosystem.

Using simple Alexa voice commands, you can control your mower from anywhere inside or outside your home (e.g., ""Alexa, tell my robot to start mowing"").

To schedule your mowing sessions, log into the STIGA.GO App, navigate to the "Scheduling" section, and select your preferred days and hours. The app allows you to fully customize the calendar or accept the recommended sessions optimized for your garden size to ensure a perfectly maintained lawn.

Nothing happens to the mowing process. STIGA robot mowers operate autonomously using their own onboard hardware, maps, and sensors.
If the STIGA.GO app disconnects or your smartphone loses internet connection, the robot will simply continue cutting the grass exactly as scheduled. Once it finishes its current task or the battery runs low, it will safely navigate back to its docking station on its own.

Yes, thanks to the multiuser function, the owner of a STIGA autonomous robot lawn mower can share the robot management with other users. All the users registered on the STIGA.GO App will have the same rights.

The Bluetooth light on the dashboard remains off during standard autonomous mowing. It blocks or blinks only during specific operations, such as the initial smartphone pairing or when a certified technician runs diagnostic service functions. If your mower is operating normally via the app, a dark Bluetooth light is completely standard.

Cleaning your STIGA autonomous robot mower is simple, but must be done safely:

1-Turn it Off: always switch off the mower completely before starting any cleaning or maintenance.
2-Dry cleaning: keep the robot in its normal working position with the dashboard closed. Use a delicate brush to remove grass clippings and a damp cloth to wipe the surfaces.
3-What to avoid: never use high-pressure washers or garden hoses, as direct water jets can damage the internal electronic components.

You should replace the blades every 3 months to be sure of optimum cutting results. The blade replacement of your STIGA autonomous robot mower is a simple procedure, it does not require technical ability and you can simply do it by yourself; just remember to use protective gloves. Watch the tutorial video.

You do not have to uninstall the STIGA reference station during winter, as it is built to withstand harsh weather. However, if you prefer maximum protection, you have two options:

-Leave it outdoors: Protect the reference station and docking base using a robust, water-resistant weather cover. Keep the charging station connected to the power grid to allow internal components to stay slightly warm and repel humidity.
-Store it indoors: Alternatively, you can easily unplug the cables, unscrew the reference station from its mount, and store it in a dry, indoor environment alongside your robot mower.

You can purchase original replacement parts, blades, and accessories directly online through the official online store or by visiting your nearest authorized dealer locator for professional assistance.

Robot lawn mowers operate at under 59 dB(A) - roughly equivalent to a normal conversation or a modern refrigerator running in the background. This makes them quiet enough to mow during the day without disturbing neighbours or household activity, unlike petrol-powered mowers which typically exceed 90 dB(A).

No, STIGA autonomous robot mowers do not require a physical boundary wire. They utilize wireless navigation powered by a combination of GNSS-RTK satellite signals and patented STIGA AGS (Active Guidance System) predictive technology to follow digital perimeters.

No, a traditional walk-behind lawn mower is no longer needed. The STIGA autonomous robot mower fully replaces standard mowers by cutting systematically and mulching daily. You may only need a small hand-held grass trimmer to touch up tight edges or vertical borders where grass meets walls.

Yes, modern robot mowers are exceptionally well-equipped to easily handle complex and irregular gardens.
Rather than relying on outdated, random bouncing movements, today's advanced models utilise systematic cutting patterns guided by cutting-edge navigation technologies. For instance, STIGA's autonomous robots combine GNSS-RTK satellite guidance (AGS technology) with Vision-based AI cameras (STIGA Vista) to actively ""see"" and intelligently map your garden in real-time.
This advanced spatial awareness allows them to efficiently navigate narrow spaces and tight corners with smooth agility. By recognising what is lawn and what is not, they safely steer around hundreds of static and moving obstacles, keeping your trees, flowerbeds, and garden furniture protected. Furthermore, these modern mowers can effortlessly manage multiple cutting areas—up to 30 different zones depending on the model—adapting perfectly to intricate layouts and uneven terrain.

Yes, autonomous robot mowers can pass through narrow spaces, navigating corridors as tight as 60 cm to 80 cm wide, depending on the model. STIGA mowers feature a compact, lightweight engineering profile that allows them to maneuver out of tight angles smoothly without leaving wheel tracks or tearing the turf.

Yes, modern garden robots, especially smart autonomous mowers, can successfully detect small objects. However, the level of detection relies entirely on the robot's onboard technology, such as AI-driven vision, LiDAR, and ultrasonic sensors.

STIGA autonomous mowers maximize this detection using integrated Vista technology, which includes:
-AI-Driven Vision: An AI-integrated HDR camera provides true visual awareness, allowing the mower to distinguish grass from fixed or moving obstacles at short and long distances.
-Advanced Sensor Suite: A combination of LiDAR, ultrasonic sensors, dual bump sensors, and a Six-Axis Inertial Movement Unit detects objects of all sizes—from forgotten toys and garden furniture to small animals.

Once an object is detected, the robot instantly calculates a safe alternative path to continue its mowing session without interruption.

Yes, STIGA autonomous robot mowers are equipped with various safety sensors, like rollover and dual bump sensors. They stop the blades immediately when the robot is turned over or bumps against an obstacle. In addition our most recent models feature Vista technology (camera) to help navigate around objects or people.

Yes. STIGA autonomous robot mowers are agile climbers engineered for hilly landscapes. Equipped with high-traction wheels and optimized weight distribution, they can reliably manage steep slopes and uneven terrains up to a 50% incline (27°) without losing satellite grip.

Yes, the robot cuts close to lawn edges. Thanks to wire-free mapping, you can use the STIGA.GO App to adjust the virtual boundary settings with millimeter accuracy, dictating exactly how close or over the edge (along pathways or flat borders) the robot should travel.

Autonomous robot mowers are highly effective at maintaining a lawn, but they are designed for continuous, light trimming rather than chopping down thick, overgrown grass all at once. Tackling tall grass requires a strategic approach to avoid straining the machine or tearing the turf.

How modern robot mowers manage dense or tall grass:

-Self-tuning cutting height: If the blades encounter high resistance from thick patches, advanced robots automatically raise their deck and progressively lower it across multiple systematic passes.
-Gradual adaptation: Instead of forcing their way through, this method ensures a clean, uniform cut while allowing the lawn to heal naturally until the desired height setting is safely reached.

The duration of a single mowing session varies from 1 to 4 hours, depending on your specific model’s battery capacity, layout complexity, and grass conditions.

You don't need to manually monitor the time: the robot manages its energy autonomously, cutting systematically until the battery runs low, at which point it returns to its docking station to recharge before resuming its schedule.

STIGA autonomous robot mowers are built with durable and strong materials. The outer shell is constructed from polypropylene, that has an ability to flex and absorb shock on impact with obstacles. It is also highly scratch-resistant. Blades are made of steel, with a particular carbon content, which guarantees more strength, while at the same time staying flexible and resistant to impact with stones or other obstacles on the lawn.

If your autonomous robot mower is completely unresponsive, it is usually due to one of two reasons:

-The security key: ensure the yellow safety key is fully inserted into its slot. The robot's electrical system will not power up without it.
-Low battery: the battery level may be too low to light up the display. Manually push the mower into the charging station and try to switch it on while it is securely docked in the base.

Lift error: This means the robot is lifted off the ground or the lift sensors are blocked. If the robot has been lifted, place it back on the ground, and reset the error with a double tap of the ON/OFF button or by restarting the robot. 

Bump error: This appears when the aesthetic cover is positioned incorrectly or the bump sensors are blocked. If the cover has been positioned incorrectly, make sure to adjust it. In order to clean the lift and bump mechanisms, first switch off the robot in a safe condition, remove the cover and clean the lift and bump mechanisms. Place the floating cover back and turn the robot on. 

Tilt/rollover error: This means the maximum slope of the working area has been exceeded or the robot has rolled-over. Reset the error with a double tap of the ON/OFF button or by restarting the robot. Return it to a permissible working condition. If the error persists, exclude the garden portion from the work area. The rollover error can also occur if the robot is overturned. In this case simply reposition it in working position and contact a service centre in case the error persists.

Wheel error message: You will see this error message whenever the wheel is blocked, eg by debris, tapes, ropes, branches etc, damaged or the electric motor has failed. Switch off the robot in a safe condition and unlock the wheel or contact an autoriozed STIGA Service center to replace the damaged wheel or motor. 

Charging error: This means, that an error occurred during charging. Please restart your robot and try again. 

Power supply issues: These appear when you are either using a non-original or non-compatible power supply unit or the power supply unit is faulty. Please replace the power supply with an original and compatible one.

The robot is stuck in 'GPS search' because the charging station is in a location with poor satellite reception. Please activate the ""Long exit function"" in the app, or move the charging station to a more open area if the problem persists. Note: If the reference station is attached to the charging base, moving it means you will need to map the area again.

For 'navigation not available', double-check that the reference station is installed correctly and connected to a power source. If you recently restarted the reference station, note that it needs about 15 minutes to reboot and start communicating with the robot. Poor cellular phone reception in the area can be another cause; if a restart doesn't fix it, the location might have insufficient network coverage.

When the robot displays ""surface too slippery"", the wheels might be dirty or clogged with mud and grass residues, the front wheels could be locked, or the terrain is uneven. It can also happen if the ground is flooded or too steep for the robot to handle safely.

""Planning in progress"" is an absolutely normal message. Before starting any cutting session, the robot automatically calculates its path. This operation lasts from a few seconds up to 1 minute.

The blade might be blocked by foreign objects (stones, twigs, toys, etc.) wrapped around the cutting device or the blade motor.

Alternatively, the grass is too high or the cutting height is set too low. Increase the cutting height via the app or carry out a preliminary cut with a traditional lawnmower. This error can also mean the blades are dirty, dull, or broken. Switch off the robot safely, clean the cutting deck, and replace any damaged components with original spare parts.

""Planning in progress"" is an absolutely normal message. Before starting any cutting session, the robot automatically calculates its path. This operation lasts from a few seconds up to 1 minute.

Docking calibration is occasionally requested by the software to realign the robot's alignment sensors with the charging base due to minor shifts in the ground or docking positioning. You can execute this sequence quickly by following the guided steps directly inside the STIGA.GO App.

The robot is either not ready to cut, in this case use the app to check error messages, or the battery is flat. If the battery is below 40%, the robot cannot be sent to work. Wait for the battery to charge.

The "Stopped" status usually indicates that the physical protective lid on the robot mower is currently open. Close the dashboard cover completely to update the status. If the message persists despite the cover being closed, contact STIGA customer service.

This error referrs to dirty or oxidised charging contacts. Please clean the charging contacts on the robot as well as on the charging station.  If the charging contacts are damaged or the problem persists after cleaning, contact our customer service centre. Another cause for the error message could be unlevelled terrain under the charging base. Please restore correct positioning of the charging base.

A lit red warning icon indicates the robot is in an abnormal safety or functional condition. Do not try to guess the issue from the keyboard: open the STIGA.GO App immediately, where the exact error code, diagnostic breakdown, and step-by-step resolution details will be displayed.

The battery you are using is not compatible with the model. Please contact an authorised dealer to replace the battery with an official STIGA spare part.

1. Debris build-up around the cutting deck: Mud, twigs, or grass clippings can throw the cutting system off balance and create noise. Remove the debris and clean the cutting deck either with a garden hose, a soft brush or wet cloth. 

2. Damaged or unbalanced blades: Blades that are chipped, bent, or worn out from hitting hard obstacles will cause the mower to vibrate. Inspect them regularly and replace if needed. Always replace the blades and their screws at the same time as a complete set to maintain perfect balance.

3. Loose components or blade screws: Over time, the screws holding the blades to the cutting disc can naturally loosen, leading to loud rattling noises. Turn off the robot and ensure all blade screws and visible fasteners are securely tightened.

4. Worn or damaged internal motors: If the blades are intact and the deck is clean, but the robot continues to vibrate or operate louder than usual, the internal blade or wheel motors may need servicing. In this scenario, you should rely on the professional hands of an authorized dealer for a maintenance check.

This is either due to incorrectly set working hours or the robot mower's internal clock is not synchronised. Restart the robot mower to force synchronisation of the clock.

This could have several reasons, like insufficient working hours. In this case simply extend working hours in the app. Is the cutting device blocked with fouling and/or residue, then switch off the robot mower in a safe condition and clean it. If the work area exceeds the capacity of the robot mower, reduce working area. Check if the batteries are nearing the end of their life cycle and replace them with original spare parts. If the batteries are not fully recharged, clean and remove any oxidation from the contact points and recharge them.

You can check directly in your STIGA.GO App if links between zones are missing, zones have been deactivate, cut-off frequency is too low, obstacles are present above the links or if there are bottlenecks or loops in the perimeter. These issues can be fixed directly via the app. Is the grass too high you can increase the cutting height or preliminary cut the area with a normal lawnmower. Are the robot or wheels dirty or clogged with mud or grass residues, switch it off in a safe condition, remove the floating cover and proceed to clean the robot mower.

Please perform the following checks: 
1. Is the programmed cut active? Check via the app or via the keypad that scheduling is activated correctly.
2. Are the working hours set correctly? Check the scheduling times via the app. Set it up again, if necessary.
3. Is the rain delay active? If rain delay is on, the robot will remain in the base for the selected time. For an immediate cut, the rain delay must be deactivated.
4. Has the flap been opened? Each time the flap has been opened, the desired cutting mode must be confirmed again.

There are three common reasons why an autonomous robot mower pauses and then resumes on its own. If the GPS signal weakens in a specific area, the robot will stop, wait for satellite coverage to improve, and then continue rather than risk navigating inaccurately. If the battery runs low mid-session, the robot returns to the docking station to recharge and then resumes from where it left off. If the rain sensor detects wet conditions, the robot pauses the session until the lawn is dry enough to cut safely.

There is nothing to worry about, if there was a problem with the blade this would be reported in the app with an error message. This behaviour can occur when the robot mower is returning to the charging station, when the robot is moving from one zone to another and in some cases when it is making internal moves within the zone.

If the blades spin but the grass remains tall, troubleshoot these areas:

-Incorrect deck height: The blade height setting might be higher than the grass itself. Lower the cutting deck height via the app or trigger a cutting device calibration.
-Overgrown lawn: If grass is excessively high, the blades may push it down instead of shearing it. Pre-cut the lawn with a traditional mower.
-Dull or broken blades: The cutting edges may be worn down or fractured. Replace the blades and cutting disc with original STIGA spare parts.

This loop is usually caused by a poor electrical connection or alignment. Clean any dirt, grease, or oxidation from the metal charging contacts on both the robot and the station, then perform a docking calibration via the STIGA.GO App.

Changing the cutting direction mid-cycle does not take effect immediately. To avoid incomplete or asymmetric patterns, the mower's software waits until the current cutting cycle for that zone is fully completed before applying the new direction setting. Depending on zone size, this may take anywhere from a few minutes to a few hours. If you want the change to take effect immediately, execute a "forced cut" on that specific zone through the STIGA.GO App.
