Robotic Lawn Mower Winter Maintenance and Storage

Winter is long and cold, especially in northern Europe. A robot mower left outdoors for months is exposed to cold, snow, ice and moisture, which can affect its lithium battery, electronics and RTK equipment and may reduce performance or cause damage. This guide explains how to prepare a robot lawn mower for winter storage and offers some maintenance advice.

How to maintain and store your robotic lawn mower in winter [General Guide]

Below is a general guide to winter maintenance and storage for robotic lawn mowers, covering the Mammotion LUBA and YUKA series. Operating procedures may differ between models, so contact us before you start if you have any questions.

1. Get your tools ready

Everything you need for a gentle, thorough clean:

• Screwdriver and Allen key.
  • Allen key: 8 mm short-arm, L-shaped hex key, 105 × 44 mm.
  • Do not use an electric screwdriver.
• Brush and lint-free cloth.
• Towel and protective gloves: Microfiber towel. Cut-resistant gloves.
• Low-pressure water hose.
• WD-40 cleaner (optional).
• Cleaning stand (optional). Sold separately.

2. Three things to avoid when maintaining a robotic lawn mower

• Never handle blades bare-handed: Protect your hands. Wear gloves whenever you remove or install the cutting disc and blades.
• Avoid harsh or corrosive cleaners: Strong acids and alkalis can damage the housing coating and seals.
• Never use a high-pressure washer: High-pressure spray can damage the seals and allow water into the mower.

3. How to maintain and store a mower

1. Disable all scheduled mowing tasks on the Mammotion app.
2. Dock the mower and charge it to at least 80%.
3. Once charging is complete, power off the mower and take out the safety key.
4. Gently wipe the entire mower with a damp towel.
5. Clean the Vision / LiDAR module. Gently wipe it with a soft, lint-free cloth.
6. Remove the blades and cutting discs. Put on gloves. Remove the cutting discs and blades. Clean off mud, debris, and tangled grass. Replace any worn blades. When flipping the mower, place a soft cloth underneath to protect the LiDAR/Vision module. Please note: Do not use an electric screwdriver.
7. Rinse gently, then air-dry. Use a low-pressure hose, then leave the mower to dry in a shaded spot. Optional: If a soft brush and a towel are enough to clean the mower, no rinsing is needed.
8. Store indoors & keep the safety key separate. Once clean and dry, reinstall the cutting discs and blades and store the mower indoors. Keep the safety key separate and refit it to the mower in spring.

4. How to maintain and store charging station & power adapter

1. Unplug before cleaning: Disconnect the power supply first.
2. Remove the ground screw: Use an Allen key to loosen and remove it.
3. Clean the charging dock: Brush away dirt underneath and wipe the surface clean.
4. Wipe the contacts and sensor: Use a lint-free cloth on the charging contacts and infrared screen.
5. Clean and store the power adapter: Wipe it with a dry towel, then store the dock and power adapter indoors. For daily use, do not place the power adapter directly on the ground, where it may be exposed to moisture. Place it about 50 cm above the ground instead.

NOTES:

Indoor storage is generally recommended once ambient temperatures drop below −20°C (−4°F). If you live somewhere with long winters and plan to recharge during storage, keep the charging station indoors too.

5. How to maintain the RTK reference station

When winter temperatures are above −20°C/−4°F

You can leave the RTK station outdoors.

1. Unplug the RTK station.
2. Wrap the cable around the station, then fasten the protective cap.
3. Cover the station with a plastic bag or weatherproof cover.

When winter temperatures are below −20°C/−4°F

1. Unplug the RTK station and remove it from the mounting pole.
2. Remove the antenna.
3. Wipe the station clean, then store it and the adapter indoors.

NOTES:

If you remove the RTK station, think carefully before removing the mounting pole. If the pole can’t be reinstalled in the same spot next season, the map may be offset and you may need to remap the lawn.

6. How to maintain the attachments & wear checks

YUKA sweeper kit

Remove the sweeper and hopper. Brush off dirt and clippings, rinse the hopper, then let everything dry before storing.

Blades & cutting disc

Look for wear, curled edges, and nicks. Replace damaged blades, and dry all parts before storage.

Tires & suspension

Clear dirt and stones from the treads. Check for cracks and make sure the wheels turn smoothly.

LET IT DRY Thorough drying helps prevent mold and odors from leftover grass residue.

Robot lawn mowers winter storage suggestions

• Recommended indoor range 0°C–25°C (optimal 10°C–25°C) / 32°F–77°F (optimal 50°F–77°F).
• Choose a dry, sheltered spot: A low-humidity basement, temperature-controlled garage, or dry utility room works well.
• Store batteries with care: If your product has a removable battery, remove it and keep it cool and dry, away from heaters and from anywhere that could freeze.
• Let everything dry completely: Make sure the mower and every component are fully dry before putting them away.
• Top up every 90 days to prevent over-discharge: During long storage, recharge to at least 80%. Let cold batteries warm up indoors for 2 hours before charging. (Why every 90 days? Lithium batteries slowly lose charge in storage; regular top-ups help keep them from running too low.)
• Keep clear of hazards: Store away from heaters, open flames and anything flammable.

Conclusion

Proper winter storage keeps your robotic lawn mower in good condition for the next season. A few simple preparations protect the mower, the battery and the charging station, and lower the risk of problems.

Your mower is then ready to deliver its best performance when spring comes, and to take over the lawn work again.
