The self-empty base and room mapping turn daily vacuuming into a once-a-quarter bag change for many pet owners, and the straight-line navigation pattern covers open layouts efficiently. Battery stamina forces mid-job recharges in homes over about 1,400 square feet, the base suction cycle roars like an upright for several seconds, and a subset of owners wrestle with app disconnects and bin sensor false alarms after months of use.
