Pet-owner guide
Pet hair changes the buying decision: brushroll design and a reliable self-empty dock matter as much as raw suction. These are the models we would shortlist for daily fur pickup.
Read guide →Carpet buying guide
For carpet, consistent coverage and a brushroll that keeps contact with fibers matter more than a long feature list. Vacuum-only models are simpler; combo models need dependable carpet detection and mop lifting.
Read guide →Hard-floor guide
On sealed hardwood, the best combo is the one that controls water, covers the room methodically and cleans its own mop pads so dirt is not spread from room to room.
Read guide →Low-maintenance guide
A self-empty dock is valuable only when the robot also navigates reliably and the dock fits your maintenance preferences. Bagless designs avoid replacement bags; sealed bags reduce contact with dust.
