Roombas always seem like a idea whose time have come -- but the actual product be not quite there . last month I decide that I be ready and buy the 564 Pet Series . we household consist of two Cavalier King Charles Spaniels -lrb- mad shedder -rrb- , one short-haired cat , and two untidy people . I schedule the Roomba to run every night at 11:00 p.m. , after we have go to bed upstairs . we do not hear it all . the area it cover include the living room , dining room , and kitchen . and every morning I empty a nearly full container -- hair & crumbs & mystery dirt . I be more than pleased at the Roomba 's performance . it be only get stick once in a collection of cable that I have since block off . I be quite happy with the purchase . as long as it keep pick up stuff I really do not know be there , I be delighted . and I be very fussy about floor . the dog do not care a whit about the machine . the cat initially look at I with a `` what fresh hell be this '' look -- but she always do that . she just give it a wide berth now .
