This is better than a butler...quieter & takes up less space & cheaper to charge it than to pay the butler! I love drinking my coffee & reading the paper & vacuming at the same time.Wheeee! Maneuverability Huh? Went waaay under the futon that I NEVER did w/ the vacume cuz I would have to get on my hands & knees. Could not be easier. Ease of Maintenance Empty a cup..how easy is that & clean the bristles as needed..SIMPLE Suction Performance My hair is down to my butt & my cat is long haired..pickes up both of our hairs & any kitty litter he tracks out of his box. Amazing what this thing picks up.
