Robot Lawn Mower Winter Storage: How to Store It Properly 22 October 2026 Having a robotic lawn mower makes life so much easier during the spring and summer months, but what should you do when it comes to winter? Proper winter storage helps protect your robot lawn mower’s battery and keeps it safe from damage. This article will explain how to clean and look after your robotic mower during the winter months. When To Stop Using Your Robotic Lawn Mower? During the autumn months in the UK, you will normally stop using your robotic mower around late October/November. Once the grass stops growing you should stop using your robotic lawn mower. Temperatures under 8 to 10°C cause your grass to grow more slowly, so mowing your lawn in frost or when it’s waterlogged can do more harm than good. Below are a few signs to help you decide when to stop using your robot lawn mower: Grass has stopped growing. Temperature drops under 10°C. Frost forming in the morning. Lawn constantly waterlogged. Make sure to give your lawn one last mow before storing your robotic lawn mower, but don’t cut the grass too short. 1. Clean Your Robot Lawn Mower As your robotic mower will have been used many times over the summer, it will have built up dirt and grass under the base. Cleaning it before winter storage helps prevent corrosion, keeps moving parts in good condition and makes spring maintenance easier. Start by switching off the mower and activating its safety lock, following the manufacturer’s instructions. Clean your robotic lawn mower by: Clearing any grass/dirt from the base of the mower and wheels. Wiping down the exterior with a wet cloth. Removing any grass stuck in the wheels. Wipe down any sensors you have access to. Leave your mower to air dry. Do not use a jet wash or any cleaning products on your robotic mower, unless your user manual says you can. 2. Check the Blades and Blade Disc Winter is the perfect time to check your robotic mower for any excessive wear and tear. If your blades have become dull or are starting to show signs of wear, you should replace them. Worn blades can tear grass rather than cut it cleanly, affecting the appearance and health of your lawn. Also check the blade disc and wheels for any signs of damage or wear. If your mower requires any parts to be replaced, it’s best to get them done now and save yourself a headache in the spring. Always follow the safety instructions provided by your manufacturer when removing or fitting new blades, and ensure you are using compatible replacement parts. 3. Robotic Lawn Mower Batteries Robotic lawn mower batteries are very important to look after over the winter months. Many robotic lawn mowers use lithium-ion batteries, which can be affected by being left uncharged or stored in low temperatures. Make sure to follow the instructions provided by your manufacturer when storing your robot lawn mower battery, as some will require you to leave the battery charged over the winter, and others may want you to switch the mower off using its proper shutdown sequence. 4. Charging Station Don’t forget your charging station will need looking after over the winter too. Refer to your user manual for instructions on how to store your charging station, as you may need to disconnect your mower and store the station inside. Some robot lawn mowers prefer you to leave their charging stations outside, but just make sure you are following the instructions from your manufacturer. Boundary wires can be left in your lawn over the winter but make sure you protect the wires from any water damage. If you don’t have boundary wires, check if you need to leave your reference station plugged in to keep the boundaries you already have. Don’t leave any wiring exposed over the winter. 5. Where To Store Your Robot Lawn Mower Finding the right place to store your robotic lawn mower is just as important as getting it ready. You want your mower to be stored somewhere dry and free from frost, ideally somewhere with a constant temperature. You can store your robotic mower in your garage (as long as it doesn’t get frost) or a dry outbuilding. Make sure your robot lawn mower is stored upright and on a flat surface, and if you have a bracket that allows you to mount your mower on the wall then you can store it like this too. Try to store your mower where it won’t be knocked over or have anything heavy placed on top. 6. Get Your Robot Lawn Mower Serviced Winter is a good time to get your robot lawn mower serviced, so it’s in good shape for next year. Depending on the robot lawn mower you have, it may include: Replacing any worn blades. Checking the battery life. Cleaning your robot lawn mower. Updating any software. Testing your robot lawn mower. Having your robotic mower serviced is beneficial if you have a larger garden or you have had to use your mower frequently. By servicing your robotic mower during the winter you can catch any issues before the spring. Not sure what your mower needs? Get in touch with our team for advice. Preparing Your Robot Lawn Mower For Spring When the temperatures start to increase and your lawn starts to grow at a faster rate, it’s time to bring your robotic mower back out. In the UK, this is usually around March/April time, depending on the weather and how your lawn looks. Once your mower is ready to go you can follow these steps: Check your mower over for any damage. Charge your battery as instructed by your user manual. Put your charging station back together and connect your robot lawn mower. Check your blades and replace if necessary. Change any settings and update software. Clear any branches/debris from your lawn before the first mow. Start your mower with a higher mow height and work your way down as the season goes on, and don’t mow your lawn if it’s frosty or waterlogged. Keep Your Robotic Mower Ready for Another Season If you follow these steps you will have no issues when storing your robotic mower over the winter.
