Winter Storage for a Robot Mower: Battery, Blades & Spring Startup
Last verified: October 2026
Everything you need to put a robot mower away right and wake it up easily — cleaning, blades, protecting the battery from an Ohio winter, and spring startup. Rather have a hand? My number is (330) 200-8042.
Wintering a Robot Mower, at a Glance
A Northeast Ohio winter is hard on anything with a battery, but a robot mower asks very little to winter well — if you do a few things in the right order. This guide covers end-of-season cleaning (power off first, mind the blades), checking the blades, storing the lithium battery indoors where it won't freeze, bringing in the base and satellite antenna, and a smooth spring startup. There's a printable version up top.
Common Questions
1 Can I just leave my robot mower in the garage all winter?
If the garage stays above freezing, yes. If it's an unheated garage or shed that drops below freezing in an Ohio winter, bring at least the battery indoors — deep cold is the single thing most likely to ruin a lithium battery. A heated garage, basement, or utility room is ideal.
2 What charge should the battery be at for storage?
Follow your manual — makers differ, but most prefer a partial charge somewhere in the middle rather than bone-empty or packed completely full. The two things to avoid are letting it freeze and letting it sit fully drained for months, either of which can leave it weak or dead by spring.
3 How do I clean it without hurting myself on the blades?
Power the mower completely off first — the real off switch, not just docking it — before you ever flip it over. Then brush and wipe grass off the top, wheels, and underside with a soft brush and a damp cloth. Wear a work glove, keep fingers clear of the cutting disc, and go easy with water.
4 Do I need to bring the satellite antenna indoors?
It's a good idea on wire-free models. The small fixed antenna or reference station is delicate, and Ohio ice and snow can damage it. Bring it in, note how it was mounted and aimed at the sky, and reinstalling it in spring takes only a few minutes. A buried boundary wire, by contrast, stays in the ground.
5 When should I start mowing again in spring?
When the grass is actively growing and the lawn has dried out from the spring wet — usually sometime in April here. Mowing soggy April ground too early just clumps the grass and can rut the soft lawn. There's no prize for the earliest mow.
6 What does the spring wake-up involve?
It's the put-away routine in reverse: recharge the battery, reinstall the base and antenna in the same clear-sky spot, update the phone app, reset your mowing schedule, and ease into the first mow once the lawn is growing. The app and schedule are exactly the parts I can help with, often right over a screen-share.
Would You Rather I Just Help?
Putting a mower to bed and waking it up are satisfying little seasonal jobs — and the fiddly parts (the app update, the schedule, getting a satellite setup to find itself again in spring) are exactly where I'm handiest. I'll give it a yearly once-over, fresh blades and all, so it's ready for summer. $99 flat for a visit, 30-day come-back-free.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
