I had gone to biglots a few days ago, not looking for anything particlar, just shopping. There on the shelf was a robomaid, $4.88 seemed pretty cheap for something that would actually work, but I figured what the hay it's $5 if it doesn't work well no huge loss. Basically all it is; is a motorized ball that sits inside this "cage" that has a magnetic cloth on the bottom, it rolls around the house and picks up dirt and hair on the floor. I brought it home, charged it up, and sent it on it's way lol. Well it works GREAT for dog hair and dust, didn't expect it to pick up anything bigger than a medium sized dust bunny. I put it to work on the kitchen floor last night while the dogs were eating, the second it bounced off the food dishes they went nuts! I decided to take the ball out of the cleaning cage and let them play with it OMG it was to funny! Since it rolls around by itself they have a heck of a time catching it, and when they do they can't pick it up in their mouths. Definatly a well spent $5 lol, it cleans the floors and when it's done, it'll entertain the dogs!
