This may sound a little silly but my husband bought me a ROOMBA automatic carpet cleaner and I first I thought, "this is probably a piece of junk with shiny buttons...there's no way it can clean a carpet!" Well, much to my surprise ROOMBA actually does work. I love that I can turn it on, close the door (block off entries that I don't want it to go in or under) and let it do its thing. This saves me time and I think it's worth the purchase. Thiema”
