I think I already write a review of this vacuum , but it must have be on the target site . anyway , this be a excellent , powerful vacuum . we have a multi-cat household and I be always amaze at how much fur and -lrb- cat litter silt -rrb- get 's pick up . grant , there be no bag so the back of the vacuum get dust powder ... so a little leak out when be use . the only con , I realize this past month . I decide to wash the filter ... not a good idea . I have to wash several time and bake in the sun , but the filter now stink ... very much . when I vacuum it smell like wet cat . Yuck ! so not a big deal ... I just realize that I have to buy new filter rather than wash they . otherwise , I love my Bissell and highly recommend it !!
