Robot mower accessories, rated honestly
The add-ons sold for robot mowers, graded on whether they are actually worth buying. None is the mower itself.
6 robot mower accessories are graded here, each with a plain verdict on whether it is worth buying. None is a substitute for the mower itself. The one genuine essential is replacement blades, a real wear part rather than an upsell; most of the rest are situational or redundant.
Accessories are add-ons, not a mower.
These are wear parts and add-ons (blades, garages, RTK antennas), not the mower itself. Some are genuinely useful, most are optional. We say plainly which are worth buying, never by who sells them. For the mowers themselves, see the robot mowers.
Every accessory, with a verdict
Ordered with the genuinely useful add-ons first. Our verdict reflects whether it is worth buying, not who sells it.
Also: cutting blades, blade pack
Genuinely essential. Dull blades tear grass instead of cutting it, which browns the tips; most makers recommend replacing every 1 to 3 months in season.
A real wear part, not an upsell. Keep a spare pack on hand.
Also: RTK antenna, reference antenna, signal booster
Helps specifically when signal is the problem. Raising or relocating the antenna, or adding the maker's extension, can fix drop-outs; it does nothing if your yard already has a clear sky view.
Worth it only if you have signal trouble under tree cover. Otherwise skip.
Also: shelter, carport, house
Modest but real: shade and rain protection reduce UV fade and keep the dock contacts cleaner, which can extend service life. Not required, since the mowers are weather-rated.
A nice-to-have for a fully exposed dock; optional if the dock sits in shade.
Also: no-go zones, magnetic strip
Mostly unnecessary on RTK/vision mowers, which hold app-set virtual boundaries well. Physical markers add belt-and-suspenders protection around fragile borders.
Usually skip. The app boundary is the real tool; add markers only for delicate beds.
Also: wheel brush, maintenance kit
Real value: caked grass unbalances the blade disc and dirty sensors cause navigation errors. A soft brush and periodic rinse (per the manual) matter more than any branded kit.
The habit matters more than the kit. A brush and the manual's routine are enough.
Also: GPS tracker, alarm
Largely redundant on modern mowers, which ship with anti-theft built in. A separate tracker helps only if you want independent recovery.
Usually redundant. Turn on the built-in anti-theft first.

How we judge an accessory
Our verdict weighs whether an add-on solves a real problem (a genuine wear part, or a fix for a specific fault such as poor satellite signal) against whether it just duplicates what the mower already does. It reflects usefulness, not who sells it or how it is marketed, so an essential wear part outranks a redundant gadget even when the gadget is pushed harder.
