Your robot mower doesn't need much attention — that's kind of the whole point. But a little seasonal care goes a long way toward keeping it running for years instead of becoming a very expensive lawn ornament.
Here's what to do (and when) to keep your mower happy throughout the year.
Spring: Wake-Up Time
Depending on where you live, this is usually March through early May. The grass is starting to grow, and your mower's been sitting all winter. Time to get it back in action.
First, the Pre-Season Checklist
Check the blades. Winter storage can cause some corrosion, especially if the mower wasn't cleaned before hibernation. Look for rust, chips, or dullness. Most blades should be replaced at least once a year anyway — spring is a good time.
Clean the underside. Flip it over and clear out any caked-on grass from last season. Compressed grass affects cutting performance and can harbor mold.
Inspect the wheels. Make sure they spin freely and aren't cracked. Debris gets stuck in there over time.
Check the battery. If your mower was stored with a dead battery, you might have reduced capacity. Most lithium batteries handle storage okay, but really old or poorly stored ones might struggle.
Update the firmware. Most modern robot mowers have app updates over winter. Connect to WiFi and check for updates before the first run.
The First Mow
Don't just let it loose on a jungle.
If your grass grew long over winter (or you live somewhere with warm winters and it never stopped), knock it down with a regular mower first. Robot mowers aren't designed for tall grass — they work best maintaining already-short lawns.
On the first run, watch it for a while. Make sure the boundary wire (if applicable) is still good, that it's not getting stuck anywhere new, and that navigation is working properly.
Spring Schedule Adjustment
Grass grows faster in spring. You might need to increase mowing frequency from your fall schedule. Start with daily or every-other-day runs and adjust based on how your lawn looks.
Also: spring means rain. Most robot mowers have rain sensors, but double-check yours is working. Running in heavy rain isn't great for the mower or your lawn.
Summer: Peak Season
This is when your mower earns its keep. Grass grows like crazy, especially early summer.
Dealing with Heat
Most robot mowers handle heat fine, but a few things to keep in mind:
Avoid midday mowing in extreme heat. Not for the mower's sake — for your lawn. Cutting grass in 95°F+ sun can stress it. Schedule morning or evening runs during heat waves.
Keep the charging station shaded if possible. Electronics and batteries prefer not to bake in direct sunlight. Some people build little covers or find naturally shaded spots.
Hydration (For Your Lawn, Not the Mower)
Robot mowers and sprinkler systems need to coordinate. You don't want your mower running through active sprinklers, and you don't want water pooling where it docks.
Most smart mowers let you schedule around irrigation. Set it up once and forget about it.
Monthly Maintenance
Every month during peak season:
- Clean the cutting deck
- Check blade sharpness (dull blades tear grass instead of cutting it cleanly)
- Wipe down sensors
- Clear any debris from wheels
- Check for firmware updates
Takes maybe 15 minutes. Way better than pushing a mower around for an hour.
Fall: Winding Down
Grass growth slows but doesn't stop (in most regions). Your mower should still run, just less frequently.
Leaf Management
Here's the thing about robot mowers and leaves: they don't mix well.
A few leaves? Fine. The mower mulches them. But a thick layer of wet leaves? That's a recipe for the mower getting stuck, blades getting gummed up, and general frustration.
You'll probably still need to rake or blow leaves periodically. Or just let the mower handle light coverage and do a cleanup pass yourself when it gets heavy.
Adjusting the Schedule
As grass growth slows, reduce mowing frequency. Maybe go from daily to every 2-3 days. Cutting dormant or slow-growing grass too often can actually damage it.
Watch your lawn. When it stops looking shaggy between mows, you can stretch the interval.
Late Fall Prep
Before your last mow of the season:
- Give the mower a thorough cleaning (you'll thank yourself in spring)
- Check blade condition — replace now if they're worn so you're ready for next year
- Note any issues that popped up during the season to address over winter
Winter: Storage Time
Unless you live somewhere grass grows year-round (looking at you, Florida), your mower needs proper winter storage.
Before Storage
Clean everything. And I mean everything. Grass, dirt, moisture — all of it needs to go. Stuff left on the mower over winter turns into crusty, corrosive gunk.
Charge the battery to about 50-70%. Don't store it fully charged or fully dead. Lithium batteries prefer mid-range storage charge.
Remove the battery if possible. Some mowers have removable batteries. If yours does, store the battery separately in a climate-controlled space.
Where to Store
Indoor storage is best. A garage, basement, or shed that doesn't get extremely cold works fine. You're mainly trying to avoid:
- Freezing temperatures (bad for batteries)
- Moisture (rust, corrosion)
- Extreme temperature swings
- Rodents (they love chewing wires, ask me how I know)
If you have to store outside, cover it properly and check on it periodically.
The Charging Station
Some people leave the charging station out year-round. Others bring it in. Depends on your climate and setup.
If you leave it out, disconnect power and maybe cover it. If you bring it in, store it with the mower.
Winter Battery Maintenance
If storing for more than a few months, check the battery charge occasionally. Top it up to that 50-70% range if it's dropped significantly. Most modern lithium batteries have very slow self-discharge, but better safe than sorry.
The FJDynamics Advantage
Quick note on our FJDynamics/Lymow mowers: they're designed with these considerations in mind.
The LiDAR navigation means no boundary wire to maintain (one less thing to worry about). The sealed designs handle weather well. And the app gives you useful maintenance reminders.
Doesn't mean they're maintenance-free — nothing mechanical is. But they're designed to make ownership as easy as possible.
Year-Round Tips
A few things that apply regardless of season:
Keep the lawn clear. Toys, tools, hoses, dog poop — anything on the lawn is something your mower might hit or get stuck on. Quick walk-through before mowing sessions helps.
Maintain your lawn, not just the mower. Aerate yearly. Fertilize appropriately. Fix bare spots. A healthy lawn is easier to mow and looks better.
Pay attention to patterns. If your mower keeps getting stuck in the same spot, fix the spot. Lower the boundary, level a bump, whatever. Don't just keep rescuing it from the same problem.
Keep the firmware updated. Manufacturers push improvements and bug fixes. Staying current keeps your mower running optimally.
Robot mowers are genuinely low-maintenance compared to traditional mowing. But "low maintenance" isn't "no maintenance." A little attention each season keeps them running for years.
And that's the whole point, right? Spend a few minutes on maintenance so you can spend zero time actually mowing. Seems like a good trade to me.
