I bought it as an electric broom that stupidly pokes into obstacles . and here - a real vacuum cleaner! and what a smart one too - he scanned and made a plan of the dwelling, divided it into zone-rooms and vacuumed himself along a verified trajectory! which rooms he marked - he will clean there! Well, or by default - everywhere. you can argue about the suction power and the quality of cleaning, but subjectively after cleaning - CLEAN! and the dust collector is full of collected debris.
