this have make vacuum the house , and do it a bit here and a bit there before it get out of hand , so much easier . it be equivalent to grab a broom and sweeping , but you do not have to fool with the dust pan . throw rug and floor , no problem ! if you want to vacuum for long period of time , this be not for you -- seem to work at full power for about 10 minute . really easy to dump out the dirt . I use the roller bar all the time , even on linoleum , as it do not work nearly as well without it . I be get rid of my full size vacuum and will never go back to have one .
