Robot vacuum accessories fall into two categories: consumables (brushes, filters, pads, bags) and upgrades (thresholds, dock mats, cable organisers). The right consumables extend life; the right upgrades reduce daily friction.
Here's what we recommend — and what to skip.
Essential consumables
Replacement intervals differ by model and by how hard the robot works, so use the schedule in your manual rather than a universal figure — a pet home gets through consumables faster than a pet-free one.
Filters: buy the manufacturer's own part where you can. Fit and airflow matter here, and poorly made aftermarket filters can restrict it.
Main brush: manufacturer parts are the safer choice, because the fit into the brush housing affects how well it picks up.
Side brushes and mop pads: established third-party multipacks are generally fine, and buying several at once is cheaper than replacing one at a time.
Dock dust bags: only fit the bag designed for your dock, and keep spares so you are not caught out mid-cycle.
Worthwhile upgrades
Threshold ramps: inexpensive, and worth it if the robot repeatedly fails at one specific transition between rooms.
Dock mat: catches drips from the dirty-water tank and mop pads. A cheap silicone mat works fine.
Cable ties and cord raisers: reduce 'robot got tangled' incidents dramatically.
Magnetic strips or virtual walls: for older models without app no-go zones. Skip on any current premium model.
Accessories to skip
Scented dock cleaners: fine if you like the smell, but plain water in the dock is what the manufacturer designed for.
'Deep clean' third-party pads with plastic bristles: often damage hardwood.
No-name replacement batteries: buy OEM or reputable third-party only — cheap batteries can swell.

Final verdict
Consumables matter — filters, brushes, and pads on a schedule pay for themselves in extended robot life. Upgrades are optional but a threshold ramp and a dock mat are almost always worth the small spend.
