Winter Storage Timeline
Refer to the timeline below to understand what to do at each stage and help your mower complete winter storage and resume normal operation smoothly:
-
Late Fall
When grass growth slows significantly for 7-14 days and nighttime temperatures drop to 5-8°C (41-46°F), complete the following:
- Final mowing
- Cleaning and inspection
- Power off the mower and store it
-
During Winter Storage
During winter storage, complete the following:
- Monthly inspection
- Inspection after extreme weather
- Inspection 2-4 weeks before restarting the mower in spring
See Maintenance Step "Winter Storage Inspections" for details.
-
Spring Restart
Before resuming mowing, complete the following:
- Pre-startup inspection
- Test mowing
- Resume mowing schedule
Important Notes
Do not mow during frost, freezing conditions, or snowfall
Lawns are more vulnerable to damage in cold or freezing conditions, which may also affect the mower's normal operation.
Do not use a high-pressure washer to clean the mower
High-pressure water may damage internal components or seals.
Do not significantly reduce the mowing height of tall grass in a single session
If the grass is tall, gradually lower the mowing height over several mowing sessions. First, bring the grass down to its normal maintenance height.
Determine When to Enter Winter Storage
Look for 3 Signs
-
Slower Grass Growth
Grass growth slows significantly for 7-14 consecutive days, and mowing patterns remain visible for an extended period after mowing.
-
Persistently Low Temperatures
Nighttime temperatures remain at 5-8°C (41-46°F) or below, or the weather forecast indicates that the first frost is approaching.
-
Deteriorating Lawn Conditions
The lawn remains wet or soft, has standing water or frost, or is covered with fallen leaves for an extended period. Mowing in these conditions may increase the risk of the mower slipping, getting stuck, or damaging the lawn.
When the Above Conditions Are Met
Consider stopping mowing and begin preparing the mower for winter storage.
Tip：The timing of winter varies by region and grass type. Consider local weather conditions and your lawn's actual condition when deciding when to put the mower into winter storage.
Prepare for Winter Storage
Final Mowing
Tip
- Avoid cutting the grass too short during the final mow before winter.
- Maintaining an appropriate grass height based on the grass type and local climate can help reduce the risk of frost damage and prolonged moisture exposure during winter.
Mowing Principle: The 1/3 Rule
Example
Scenario 1: Can Be Cut to the Target Height in One Step
Current Grass Height: 6cm--Target Height: 4cm
Cutting 2 cm removes exactly one-third of the current grass height, so the target height can be reached in a single mowing session.
Scenario 2: Requires Multiple Mowing Sessions
Current Grass Height: 9cm--Step 1: 6cm--Target Height: 4cm
First, reduce the grass height from 9 cm to approximately 6 cm. After a few days, reduce it further from 6 cm to 4 cm.
Do not cut the grass directly from 9 cm to 4 cm, as this would remove 5 cm of grass, exceeding one-third of its original height.
Note: The heights above are for reference only. Always follow the product instructions and consider your lawn's condition when adjusting the cutting height.
When to Mow: Mow Only When the Grass and Ground Are Mostly Dry
- After Frost: Do not mow immediately.
- Standing Water: Do not mow.
- After Heavy Rain: Do not mow immediately.
- Sunny and Dry Conditions: Mowing is permitted.
Storage Battery Level
Charge the mower battery to 50%-70% before storage. Store the mower at room temperature (15-25°C / 59-77°F).
Note: Avoid storing the mower for extended periods with the battery fully charged (100%) or nearly empty, as this may cause irreversible loss of battery capacity.
Power Off for Storage
Press and hold the OK button for 3 seconds to power off the mower.
Cleaning and Inspecting Components
Read the following safety instructions before operation:
- Always wear enclosed footwear and full length pants during maintenance. Sandals and bare feet are strictly prohibited.
- Always turn the mower over on a soft surface gently and do not drag the mower while it is upside down.
- Do not use gasoline, alcohol, or other corrosive solvents to clean any parts of the product.
- Refrain from rinsing the mower with a high-pressure washer with pressure higher than 12.0 MPa.
Before cleaning, make sure that:
- The mower is powered off.
- The screws of the compartment cover are fully tightened to seal the mower.
Chassis

- Cracks / Deformation / Looseness → Stop using the mower and contact after-sales service.
Cameras
First, dampen the camera lenses, then wipe them clean with a soft cloth.
- Cracked camera window / Internal condensation / Persistent false alarms → Contact after-sales service.
LiDAR (Z1 LiDAR)
- Remove the upper body cover.
- First, dampen the LiDAR sensor, then wipe it carefully with the provided lint-free cloth.
Blades and Screws
Power off the mower and wear cut-resistant gloves before handling the blades and screws.
Remove the blades and screws according to the instructions in the user manual. Replace them as a set in spring.
Charging Contacts
Clean the charging contacts on the mower with a soft, dry cloth.
Make sure the contacts have completely dried before restarting the mower.
- Burn marks / Obvious corrosion → Contact after-sales service.
Charging Station
Unplug the charging station from the power outlet before cleaning it.
Rinse the charging base plate with a hose, then wipe away dirt from the charging contacts and docking markers with a cloth.
- Damaged cable / Water in the plug / Cracked housing → Do not power on the charging station. Contact after-sales service.
Remove and Store Outdoor Components
Power Outlet and Cables
Unplug the charging station from the power outlet, remove the cables, and store them indoors in a dry place.
Charging Station Base Plate
Remove the upper part of the charging station and store it indoors. The charging station base plate can remain outdoors during long-term storage.
RTK Reference Station
If your mower is equipped with an RTK reference station, it is recommended that you leave the station in its original position. If its position changes, you may need to remap the lawn when resuming mowing in spring. You can place a protective cover over the station to shield it from direct exposure to rain and snow.
Store in a Suitable Environment
Storage Position
Place the mower upright with all four wheels resting on the ground, or mount it on a wall. Do not place heavy objects on it.
Environment
Store the mower on a level surface in a dry, frost-free, well-ventilated area away from heat sources. Keep children and pets away from the mower.
Winter Storage Inspections
Inspect the mower during winter storage as follows:
Monthly Inspection
- Check the storage area for dampness or condensation. Ensure adequate ventilation and protection against moisture.
- Check whether the mower has tipped over or has heavy objects placed on it. Keep the mower in its normal storage position.
- Check the mower for rust, mold, or insect damage.
- Check if the mower's battery level is below 50%. It is recommended to maintain a battery level of 50%-70%.
Notes
- Do not leave the mower connected to power for extended periods. After checking the battery level or charging it to 50%-70%, power off the mower again.
- Do not charge the mower in low-temperature conditions. If the ambient temperature is below 4°C, move the mower indoors before charging.
Inspection After Extreme Weather
Check the charging station base plate and RTK reference station (if equipped) for damage caused by snow, ice, standing water, fallen branches, or strong winds during outdoor storage.
Note
Disconnect the power before inspecting the equipment. If you notice any signs of damage or water ingress, do not turn the equipment back on.
Inspection 2-4 Weeks Before Spring Restart
- Consider preparing the necessary accessories and scheduling a maintenance appointment in advance, if available locally, to avoid the spring rush and reduce waiting times.
- Check that the mower's WiFi connection is working properly.
When to Contact After-Sales Service
If any of the following conditions occur, contact customer service through the app or an official after-sales service channel:
- The battery is swollen, has an unusual odor, becomes abnormally hot, cannot be charged, or shows an unusual decrease in battery level after long-term storage.
- Condensation has formed inside a sensor, or water has entered the mower or charging tower. A cable is damaged, or charging contacts are burnt.
- The blade disc or wheels rotate unevenly, wobble, or make abnormal noises, or there are cracks in the mower body.
Spring Restart
Inspect and Clean the Lawn
Check Whether the Lawn Is Ready
- The lawn is free of frost, snow, and large areas of standing water.
- The ground is firm and does not sink under pressure.
- The grass has clearly resumed growing.
Clean the Lawn
- Remove branches, stones, toys, hoses, cables, animal burrows, construction materials, thick layers of fallen leaves, and other obstacles.
- Check whether the ground is uneven or slippery. If necessary, level the area to facilitate mower passage.
Inspect the Mower
- Install and secure the charging station and RTK reference station (if equipped).
- Check the wheels, sensors, charging contacts, and chassis.
- Install the blades and screws according to the instructions in the user manual.
Blade Replacement Guidelines
- If the grass tips turn white or appear torn after mowing, or if cutting efficiency decreases significantly, the blades may be dull or damaged.
- Replace all blades on the same blade disc, along with their corresponding screws, as instructed in the user manual to prevent the blades from coming loose during operation.
- Do not sharpen the blades yourself, as this may affect cutting performance.
- Do not install third-party blades that differ from the original blades in size, quality, or mounting-hole position.
Power On and Connect to the Network
- Connect the power according to the user manual and ensure that the charging station and RTK reference station (if equipped) power on properly.
- Check the mower's WiFi connection and update the firmware.
Test Mowing and Resume the Mowing Schedule
- For the first mowing session, do not immediately set the mowing height to last year's minimum. Follow the 1/3 rule by cutting no more than 1/3 of the current grass height in a single session (see Final Mowing under Prepare for Winter Storage). Start with a higher mowing height and gradually lower it over several sessions.
- Check whether the lawn map, No-Go Zones, mowing schedule, and other settings meet your current needs.
- During the first mowing session, operate the mower for 10-20 minutes under supervision. Check that the following functions work properly: leaving the charging station and returning to charge, positioning and obstacle avoidance, edge cutting and turning, cutting, and emergency stop.
- Before resuming normal mowing tasks, ensure there are no issues such as slipping, digging into the ground, getting stuck, missed areas, abnormal noises, or failure to return to the charging station.
During the first week of operation:
- Operate the mower during the daytime and supervise it whenever possible.
- Check the task records and any reported abnormalities after each mowing session.
- Pay particular attention to mowing performance in areas with wet or soft ground, on slopes, around tree roots, and in narrow passages.
Lawn Care Tips
The 1/3 Rule
Cut no more than 1/3 of the current grass height per mowing session, ensuring that at least 2/3 remains.
If the target mowing height is 4 cm and the current grass height is 9 cm, the recommended minimum mowing height for the first session is 6 cm. Lower the mowing height to the target of 4 cm during the second session.
Why Should the Mower Follow the 1/3 Rule?
- During normal use, the mower can trim small amounts of grass frequently. However, after a long vacation, a rainy season, winter storage, or repairs, the grass may be significantly taller than its normal mowing height. Follow the 1/3 rule to avoid damaging the lawn.
- Setting the mowing height too low during the first session after an extended period without mowing can produce excessive grass clippings, leading to clipping buildup, increased load on the blade disc, torn grass blades, and missed areas.
- Check the date of the last mowing session in the app to estimate grass growth, then gradually lower the mowing height to the target level over several sessions.
Mowing Frequency and Environmental Conditions
Mowing frequency
Adjust mowing frequency based on the grass growth rate rather than a fixed number of sessions per week. Increase mowing frequency during warm, humid periods and reduce it during dry, very hot, or cold periods.
Mowing conditions
Mow when the grass is relatively dry and the ground is firm. Avoid mowing immediately after frost or snowmelt, heavy rain, or irrigation, or during extreme heat.
Tip
Change the mowing direction regularly to prevent the grass from being flattened and reduce lawn compression marks and wheel tracks caused by repeatedly following the same path.
Mowing Strategies for Different Seasons, Times, and Weather Conditions
When Grass Grows Rapidly in Spring
- Increase mowing frequency.
- Set the mowing height to at least 2/3 of the current grass height, and lower it gradually over several sessions.
- Inspect the blades more frequently.
Avoid cutting too much grass at once, as this can cause grass clippings to clump together. Follow the 1/3 rule to avoid damaging the lawn.
After Fallen Leaves or Fruit in Fall
- Remove thick layers of fallen leaves before mowing.
- Set areas with fallen fruit as temporary No-Go Zones. Remove the fruit before deleting the No-Go Zones and resuming mowing in those areas.
Thick layers of leaves can cover the grass and clog the blade disc, affecting the mower's positioning and cutting performance.
For Newly Seeded or Overseeded Lawns
Temporarily set the area as a No-Go Zone and resume mowing only after the grass has established a strong root system.
High Temperatures / Drought
Consider increasing the mowing height, reducing the mowing frequency, and avoiding mowing during the hottest part of the day.
Keeping the grass longer helps shade the soil from direct sunlight, reduce soil temperature, and limit water evaporation.
After Continuous Rain
- Wait until the grass and ground are mostly dry before mowing.
- If necessary, pause mowing on slopes or soft ground.
Wet grass can easily stick to the mower's components, while soft ground can cause the mower to slip or sink into the ground.
Frost / Snow
Stop mowing and wait until the frost or snow has completely melted and the ground is firm enough for mowing before resuming.
