Publication number: 20090165822Abstract: An extraction cleaning apparatus includes separate cleaning tanks for water and detergent and optionally also for rinse agent. The apparatus is able to sense its direction of travel and/or rate of travel and to control the cleaning liquid composition and/or rate of its delivery onto the floor in accordance therewith. For example, the apparatus is able to dispense detergent at a higher rate when the forward rate of travel increases and to dispense only water and/or rinse agent in the reverse direction.Type: ApplicationFiled: September 24, 2008Publication date: July 2, 2009Inventors: RONALD P. KINTZ, Greg A. Bilek, Andrew C. Budd, David A. Cotsmire, Evan A. Gordon, Touby Khamphilipanyo, Jeff S. Louis

Patent number: 7159277Abstract: A vacuum cleaner is provided having a suction nozzle comprised of a transparent agitator housing and an opaque suction nozzle body. The agitator housing forms a downwardly disposed nozzle chamber divided into a right and left agitator chamber. The right and left agitator chambers each have a forward or front suction duct adjacent the front edges of the respective agitator chambers. The right and left agitator chambers also each have a rearward or rear suction duct adjacent the rear edges of the respective agitator chambers. A nozzle liner is also disposed within the nozzle chamber partially forming a right and left dirt and air passage over the right and left agitator chambers, respectively, to fluidly connect the respective front suction ducts with the rear discharge ports located in the rear of each of the right and left agitator chambers. The rear suction ducts are also fluidly connected to respective rear discharge ports to remove dirt particles.Type: GrantFiled: May 8, 2002Date of Patent: January 9, 2007Assignee: The Hoover CompanyInventors: Ryan S.

Patent number: 6818032Abstract: A dirt collecting system for a vacuum cleaner includes a dirt cup formed with a first dirt collecting chamber and a second dirt collecting chamber separated by an apertured wall. An inlet opening is formed in the dirt cup and communicates with the first dirt collecting chamber for inputting a stream of dirt laden air into the first dirt collecting chamber. An exhaust opening is formed in the second dirt collecting chamber for allowing the filtered air stream to exit the dirt cup. The aperture wall includes a pre-filter for filtering coarse particles from a stream of dirt laden and depositing the coarse particles in the first dirt collecting chamber. A filter member is positioned within the second dirt collecting chamber and communicates with the exhaust port. The filter element filters fine particles from the air stream and deposits the fine particles within the second dirt collecting chamber.Type: GrantFiled: June 21, 2002Date of Patent: November 16, 2004Inventors: Greg A. Bilek, Steven W. Blate, Nick M. Bosyj, Donald A. Coates, Arne J. Diehl, Kurt D. Harsh, Raymond L. Lawter, Jackson W. Wegelin
