Just about to order a roomba 605 robot Hoover thingy. A friend swears by hers. Says she puts it in on when she leaves for work etc. And goes back to recharge itself. We have wooden floors throughout downstairs and a dog. Doesn't moult but the grit from walks is everywhere! I really don't have time to Hoover daily so I am hoping this will help. My friend also says the stairs are much cleaner as less dirt is stomped up them. Found one for £190, please tell me your views!
