I buy the iRobot 564 Pet Series , as we just get a puppy for Christmas . I want something to help I keep the pet fur and grass under control on my hardwood floor and area rug . I be so completely impressed with this `` vacuum '' . it truly do a great job , and so far , really have not have any issue navigate around we furniture . I would say it do as good a job -lrb- maybe better -rrb- as my regular vacuum . there be some area it struggle with , such as my flooring transition -lrb- tile to hardwood -rrb- , but it be really no big deal . it get I 98 % there , so I would say that be a win . something I be not really expect be how well it also vacuum my carpet . I just set it in a bedroom and shut the door . it be do in 20 - 25 minute , and look great . anyway , if you be consider purchase one of these , I would say you can not lose ! not to mention , my 4 YO son and dog love it . ton of entertainment !
