(Disclaimer: As I live in Mexico this was bought on the BBS). As another reviewer pointed out, it's not perfect, but it's definitely worth the money. We have 4 rescue dogs that shed like they are getting paid for their hair. We have a cleaning lady 2 times a week but the fur/hair builds up to the point where it's embarrassing. And we sweep when she's not around. I saw this on a BBS and threw it in my shopping cart hoping it would save the wool. WOW! It does. No, patterns are not always logical; No the whole floor may not be covered etc etc but it does an amazing job. For the money it cost and the headache it saved, I wholeheartedly recommend this little beast.
