Quick answer
The accessories worth owning are the ones that keep the mower working: replacement blades (a genuine consumable), a garage or cover to protect the dock, and a wire repair kit if you have a boundary-wire model. Most other add-ons are optional at best. Whatever you buy, match it to your exact model, because blades and fittings aren’t universal. These also make sensible gifts for someone who already owns a mower.
Once you own a robot mower, the accessories start appearing: garages, covers, spare blades, cleaning kits, add-on gadgets. Some are genuinely useful and some are money you don’t need to spend. Here’s an honest sort, and it doubles as a gift list for the robot mower owner in your life.
MowReview hasn’t tested these accessories. Buy to match your specific model, and check the current price before ordering.
Worth buying
The one true consumable
Replacement blades (and screws)
Not optional, and the most useful thing to keep on hand. Robot mower blades are small and light, and they dull with use, which leaves grass torn and brown rather than cleanly cut. Husqvarna recommends fitting new blades and screws before winter storage each year, and replacing the whole set together so the cutting disc stays balanced. Dense or sandy conditions wear them faster, so Southern lawns with a long season get through more.
Good for
- Every owner, every season
- A practical gift, if you know the exact model
Less good for
- Nobody, but you must match the exact model, since blades aren’t interchangeable between mowers
Protects the part that stays outside
A dock garage or cover
The charging station usually lives outdoors, and sun, rain and leaves are hard on it. Segway notes that if the dock is left outside through snow and ice without protection, electrical contacts and cables can corrode. A garage (a small roofed shelter over the dock) or a waterproof cover shields it, keeps leaves off the contacts, and can extend the dock’s life. A cover is the cheaper option; a garage protects the mower while it charges too.
Good for
- Docks in the open, exposed to sun and weather
- Keeping leaves off the charging contacts in fall
Less good for
- Docks already under cover, such as beside a wall or eave
- Buyers who’ll bring the whole dock indoors for winter anyway
Only if you have a boundary wire
Boundary wire repair kit
If your mower uses a boundary wire, a break stops it dead until repaired, and a spade, an aerator or an animal can cause one. A repair kit of connectors and spare wire (or a wire-break detector for larger lawns) turns a season-ending problem into a ten-minute fix. Wire-free owners don’t need this at all.
Good for
- Boundary-wire mower owners
- Large wired lawns, where finding a break is harder
Less good for
- Wire-free (RTK, LiDAR or camera) mowers, which have no wire
Maybe, depending on your situation
- A cleaning brush or kit. Useful, but an old washing-up brush and a dry cloth do the same job. Buy one if you like having the right tool; skip it if you don’t.
- A wall mount for the mower. Handy for winter storage if floor space is tight and it frees you from lifting the mower on and off the ground. Only some models offer one.
- Spare/extra battery. Rarely needed for a mower that docks and recharges itself, but occasionally useful on a very large lawn. Check whether your model even supports it.
- Anti-theft accessories. Many mowers already include a PIN, alarm or tracking. Add-ons make sense only if yours lacks them and theft is a real concern in your area.
Usually skip
- Universal blades from unknown sellers. Cheap third-party blades that don’t match your model can unbalance the disc or fit poorly. The saving isn’t worth it on a safety-critical part.
- Decorative wraps and stickers. Harmless fun, but they’re not doing anything for the mowing.
- Gadgets that duplicate the app. If the mower’s own app already schedules, maps and sets no-go zones, you rarely need a separate accessory to do the same.
Match everything to your exact model
Blades, mounts and dock covers are model-specific. A blade set for one mower can be wrong for another even from the same brand. Before buying any accessory, confirm it’s listed as compatible with your exact model and year, and when in doubt, buy the manufacturer’s own part.

As a gift
Accessories solve the problem with giving a robot mower itself: you don’t have to guess about someone’s yard. A set of model-matched replacement blades, a dock cover or a wall mount is genuinely useful to any owner and impossible to get wrong on size or slope. If you’re considering the mower itself as a gift, our guide to giving a robot mower as a Christmas gift covers the bigger decision.
Questions
What accessories do I actually need for a robot mower?
Really just replacement blades, which are a consumable every owner needs. Beyond that, a dock cover or garage if the charging station is exposed, and a wire repair kit if you have a boundary-wire model. Most other accessories are optional.
Are third-party robot mower blades safe to use?
Match blades to your exact model. Cheap universal blades from unknown sellers can fit poorly or unbalance the cutting disc, which is a safety-critical part. When in doubt, buy the manufacturer’s own blades, and always replace the full set together.
Do I need a garage for my robot mower’s charging station?
Not essential, but useful if the dock sits in the open. Segway notes that an unprotected dock left through snow and ice can suffer corroded contacts and cables. A cover or garage helps, though bringing the dock indoors for winter does the same job.
Buying the mower itself?
Accessories are the easy part. Getting the right mower for your yard is what matters most.
