By late October most British lawns are slowing down, and your robot lawn mower is entering its trickiest stretch of the year: fallen leaves, constant damp, the first frosts and, finally, winter storage. What you do between now and March decides, more than anything else, how many seasons you get out of the battery.
This guide covers what to change in autumn, when to bring the mower in depending on where you live, how to winterise it properly and why the next few weeks are also the best time to buy one.
Autumn settings: fewer hours, higher cut
- Cut back the hours. Grass grows far more slowly; mowing every day adds nothing and wears the battery and blades. Some models do this automatically with weather- or growth-based timers.
- Raise the cutting height. Slightly longer grass copes better with cold, shade and wear over winter, and is less prone to moss.
- Mow in the dry part of the day. Skip the dewy mornings: wet grass clumps and the robot slips, particularly on banks and clay.
- Turn on the rain sensor if your model has one, or set a rain delay in the app.
- Keep it to daylight. Hedgehogs feed hard in autumn to build up reserves before hibernating, so never let the schedule creep into the evening as the days shorten.
Fallen leaves: the silent enemy
A robot mower is not a leaf collector. It will shred a light scattering without fuss, but a mat of wet leaves smothers the grass (which yellows for lack of light), clogs the cutting disc and, on vision-based robots, confuses edge detection. Rake or blow the lawn once or twice a week while the leaves are falling and let the robot tidy up after. Pile the leaves in a quiet corner and you've built a hedgehog a winter home.
When to bring the robot in
| Area | Typical last cut | Typical return |
|---|---|---|
| Scotland, northern England, upland areas | Mid to late October | April |
| Midlands, Wales, Northern Ireland | Late October to mid November | Late March to April |
| Southern England and coastal South West | November, or reduced use into December in mild years | March |
The real guide isn't the date but the grass: once it stops growing visibly (soil temperatures below roughly 5-6 °C) and ground frosts arrive, it's time to put the mower away. Always check your manual for the minimum operating and storage temperatures.
How to winterise a robot mower, step by step
- Charge the battery as the manufacturer advises (many recommend fully or partly charged, never flat).
- Clean the underside, cutting disc and wheels thoroughly with a brush. Never use a hose or pressure washer.
- Check and change the blades now, so it's ready for spring.
- Store it indoors, dry and frost-free (a garage, utility room or insulated shed), lying flat or on the maker's wall bracket.
- Charging station: unplug it from the mains. Many manufacturers recommend bringing it in too; the boundary wire can stay in the ground.
- Wire-free with an RTK antenna: check whether your maker advises removing or protecting it over winter.
Put a reminder in your phone for the day you stored it, and check the battery charge around January if the manual recommends it. While it's indoors, note its serial number and make sure the PIN and account lock are active; robot mower theft spikes in spring.
Spring start-up
When it goes back out: clean the charging contacts, check the boundary wire (frost heave and moles are hard on it), update the firmware, confirm the map is still valid and start with a high cutting height that you lower gradually. If the lawn is long after a mild winter, give it a first cut with a conventional mower before handing over to the robot.
If you're buying this winter: models we recommend
Robot mowers are seasonal products. The biggest discounts usually come around Black Friday in late November, when brands clear stock before new models launch, and in the run-up to spring. Buying in November has another advantage: you can install it calmly over winter and have it running from the first cut in March. Check the current price on Amazon for any of these.

Can I leave my robot mower outside over winter?
It's not recommended. Frost and months of damp are hard on the battery and electronics. Clean it, charge it as the manual advises and store it somewhere dry and frost-free, such as a garage or utility room.
Do I need to remove the boundary wire for winter?
No. The wire can stay in the ground. Check it in spring in case frost heave or moles have damaged it.
When should I stop using my robot mower in the UK?
When the grass stops visibly growing and ground frosts begin: typically mid to late October in Scotland and the north, and November in southern England, with some mild areas mowing lightly into December.
Will a robot mower pick up leaves?
No. It will shred a light scattering, but a mat of wet leaves clogs the cutting disc and smothers the grass. Rake or blow the lawn regularly while leaves are falling and let the robot tidy up.
When is the best time to buy a robot lawn mower?
Black Friday in late November and the run-up to spring usually bring the best prices. Buying in autumn also gives you time to install it over winter and start mowing in March.
