I purchase this to pick up cat litter from wood floor . the suction be so weak that I have to use the beater bar on wood floor ; even then it often require several pass to pick up litter . just when you think it have finally suck up the litter or other debris , it will spit it out a few pass later or if you even slightly jar the vacuum . very disappointing ! I wish I have return this piece of crap when I could . I be look for a replacement and will be more careful to research Amazon review specifically re cat litter and hardwood floor -lrb- live and learn -rrb- !
