How can I fix this? Answer: To start, remove the front tank and the SmartMix® tank on the back of the cleaner. Next, tilt the cleaner backwards so it’s resting on its handle. Then, wipe all dirt, hair, and lint from the underside. Be sure to clean area between the brushes. Empty the dirty water tank and rinse it out. To get up the spots, re-clean the previously cleaned areas, working in small sections.
