As the mowing season comes to an end, it’s worth taking a little time to prepare your robot mower for the colder months ahead. Wet conditions, frost, and long periods without use can all affect performance if the mower is simply left outside through winter.
Proper robot lawn mower winter storage helps protect the battery, reduce wear on important components, and make spring setup much easier. In this guide, you’ll learn when to store your robot mower, how to prepare it properly, and what to check before putting it away for winter in the UK.
When Should You Store a Robot Mower for Winter?
In most parts of the UK, you’ll usually stop using your robot mower sometime between late October and early November . The exact timing depends on the weather, your lawn, and how quickly grass growth slows down in your area.
A good rule is to start thinking about robot lawn mower winter storage once temperatures regularly drop below around 5°C overnight and the grass stops needing weekly cuts. Frosty mornings, heavy rain, and waterlogged lawns are also signs that the mowing season is winding down.
It’s best not to wait until the first hard frost arrives . Cold and damp conditions can affect the battery, charging contacts, and sensors if the mower keeps sitting outside without much use. UK winters are especially tough on garden equipment because of the constant moisture and sudden temperature changes.
That said, you don’t need to rush to store it away at the first chilly evening. During milder autumn weeks, your lawn may still need an occasional trim. Many people reduce mowing schedules gradually through October before stopping completely once growth slows right down.
Before storing the mower, try to do one final tidy cut on a dry day . Leaving the grass slightly longer over winter often works better for UK lawns than cutting it very short before dormancy.
How to Prepare the Robot Mower Before Winter Storage
Once you’ve decided it’s time to stop mowing for the season, it’s worth giving your robot mower a proper winter prep rather than simply parking it in the shed and forgetting about it. A few simple steps now can help prevent battery issues, moisture damage, and annoying startup problems when spring arrives again.
Give the Mower a Thorough Clean
Start with a full clean after the final mow of the year. Grass clippings, mud, wet leaves, and small bits of debris often build up around the wheels, blades, and underside during autumn.
Switch the mower off fully before cleaning. Then:
- Brush away dried grass and dirt
- Wipe the outer casing with a damp cloth
- Clean around the wheels and cutting deck
- Gently wipe sensors and charging contacts
If damp grass sits underneath the mower all winter, it can lead to corrosion and unpleasant smells by spring. Dirty sensors can also affect navigation once the mower is back in use.
Avoid using a pressure washer unless your specific model says it’s safe. Too much water pressure can damage seals or force moisture into sensitive electronics.
Check the Blades Before Storage
Winter is also a good time to inspect the cutting blades closely. If they look chipped, bent, or dull, replace them now rather than waiting until the first cut of spring.
Sharp blades help the mower cut cleanly and put less strain on the motor and battery. Leaving worn blades attached through winter can also increase the chance of rust forming.
For most UK gardens, blade wear tends to build up faster during autumn because lawns stay wetter and softer for longer.
Charge the Battery Properly
The battery is one of the most important parts of any robot mower, and cold weather can shorten its lifespan if it’s stored incorrectly.
Most manufacturers recommend storing the mower with some charge left in the battery rather than completely empty. Depending on the model, that usually means somewhere between 50% and 80% .
Avoid:
- Leaving the battery fully drained
- Storing the mower in freezing temperatures
- Leaving it outside through winter
If your mower has a removable battery, store it indoors in a dry, frost-free place. Garages and utility rooms usually work well, as long as they stay reasonably dry.
Turn Off Schedules and Smart Features
It’s easy to forget this step, especially with app-connected robot mowers.
Before storage:
- Disable automatic mowing schedules
- Turn the mower off fully
- Disconnect smart routines if needed
This helps prevent the mower from trying to start itself during winter or slowly draining the battery in standby mode.
If your mower uses mapping or RTK navigation, it’s also worth checking that maps and settings are backed up in the app before powering everything down for the season.
Clean and Protect the Charging Station
When winterproofing a robotic mower, the charging station needs attention too. Over autumn, charging contacts often collect dirt, moisture, and small bits of grass.
Before winter:
- Disconnect the power supply
- Inspect all cables and connectors for signs of wear or corrosion
- Wipe the charging contacts clean
- Remove leaves and debris around the base
Some charging stations can stay outdoors with weather protection, but many manufacturers recommend bringing them inside during winter , especially in colder or very wet parts of the UK.
If you do leave the base outside, use a protective cover and make sure water cannot collect around the connectors.
Store the Mower Somewhere Dry and Frost-Free
Where you store the mower matters just as much as how you prepare it.
The ideal spot should be:
- Dry
- Frost-free
- Well ventilated
- Away from direct damp or condensation
A garage, insulated shed, utility room, or basement usually works best . Try not to leave the mower directly on a cold concrete floor if the space gets damp in winter. A shelf or wooden board can help keep moisture away.
It’s also a good idea to loosely cover the mower to keep dust off while still allowing airflow around it.
Best eufy Robot Lawn Mowers for Easy Seasonal Care
If you want a mower that makes lawn care easier from spring through autumn, the eufy Robot Lawn Mower E15 and E18 are worth considering. They’re designed for hands-free mowing without the usual hassle of boundary wires, which is a big plus if you want a cleaner setup at the start of the mowing season and less to deal with before winter storage.
Both models use pure vision FSD technology , combining high-precision cameras with AI-powered navigation to map your garden automatically, plan efficient mowing routes, and avoid common obstacles along the way.
That means there’s no need to lay perimeter wires or install an RTK station. For many UK gardens, setup feels much less fiddly, especially if you have flower beds, paving, narrow lawn edges, or garden layouts that change through the year.
You can use the app to set mowing zones , create no-go areas, adjust schedules, and check mowing progress remotely. The Ride-on-Edge feature helps the mowers cut closer along borders too, so there’s usually less trimming left to do afterwards.

FAQs
Can robot mowers stay outside in winter?
It’s not recommended to leave your robot mower outside during winter. Exposure to frost, rain, and fluctuating temperatures can damage the battery, electronics, and sensitive sensors. Storing it in a dry, frost-free place ensures it stays in good condition.
Should I charge the battery before storage?
Yes. Fully or partially charging the battery (depending on the manufacturer’s recommendation) before storage prevents deep discharge and prolongs its lifespan. Always power off the mower after charging for optimal winter care.
Should you cut grass in winter?
Generally, no. Grass growth slows significantly in winter, and cutting frosty or dormant grass can stress the lawn and damage both the grass and your mower. Wait until spring when growth resumes for safe mowing.
Where should I store a robot mower?
Store your robot mower in a cool, dry, and frost-free location, such as a garage, shed, or utility room. Keep it off damp floors, and cover it to protect against dust while ensuring good ventilation.
What happens to the residual data traffic of my robot lawn mower when I put it away for winter?
Most modern robot mowers pause any data collection or cloud activity when placed in hibernation or storage mode. Your mowing schedules and maps remain saved, ready to resume once the mower is reactivated in spring.
When can I use my robot lawn mower again after winter?
You can start using your mower once temperatures rise and the grass begins growing, usually in early spring. Before mowing, check that the battery is charged, the blades are sharp, and sensors are clean for safe and efficient operation.
