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'd buy — and what we'd skip.
Essential consumables
Genuine replacement filters (every 3 months): always buy OEM. Aftermarket filters are hit or miss and can reduce suction.
Main brush replacement (every 6-12 months): OEM again — the tolerances matter.
Side brushes (every 3-6 months): safe to buy multipacks of quality third-party versions.
Mop pads (every 3-6 months): buy in bulk. Washable microfiber pads from major brands last longer than the OEM pads.
Sealed-bag replacements (every 45-60 days): stock 6 at a time.
Worthwhile upgrades
Threshold ramps: essential if the robot struggles with a specific transition. $15-$25.
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 are non-negotiable — 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.
