This cleaner is easy to use and appears to remove a lot of dirt from the carpet. However, when used on a light colored carpet it leaves streaking and spots. When I cleaned it in a tub I noticed a dirty water exiting the suction fan vent on the bottom of the main housing. Evidently the baffling in the suction tank does not prevent dirty water/solution from entering the fan duct. Fix this and the its a 5 star product.
