Are you looking for the most effective way to clean your carpets, stairs and upholstery? Then the BISSELL PowerWashTM Premier upright carpet cleaner is the best choice for you. Vacuuming removes dry dirt and debris mostly from the surface of carpets. Deep cleaning removes the embedded dirt and soils that vacuums leave behind, leaving carpets up to 10 times cleaner than vacuuming alone. Heat from the machine’s motor is cleverly redirected into a vent that is located beneath the machine’s water tank to keep water at a constant cleaning temperature. It also enters the brush chamber to help heat the brushes and carpet to improve the cleaning process.
