Abstract: Exemplary foam-at-a-distance systems, refill units and foam generators are disclosed herein. An exemplary foam generator includes a body having an inlet for receiving air and an inlet for receiving liquid. The foam generator includes a plurality of baffles located within the body. A plurality of elongated spaces are formed at least in part by the baffles. The elongated spaces have a length that is greater than a width.

Abstract: Embodiments of sequenced foam pumps, refill units and dispensers are disclosed herein. One exemplary refill unit includes a container for holding a foamable liquid and a sequenced pump. The sequenced pump has a housing with a chamber located within the housing. There is an air inlet and a liquid inlet into the chamber. A hollow valve stem is movable within the chamber. A sealing member forms a seal between the valve stem and the chamber. When the valve stem is in a first position liquid flows into the chamber and air in the chamber flows into the container; and when the valve stem is in a second position, the sealing member seals off the liquid inlet, and air travels through the air inlet and mixes with the liquid in the chamber. The air and liquid mixture travels through the center of the valve stem and out of an outlet.

Abstract: Dispensers, refill units and pumps are disclosed herein. The refill units include a container secured to a pump. Some exemplary refill units for dispensers include a container for holding a liquid and a post seal pump. As the post seal pump operates, a piston moves up and down over the pump seal. When the piston shaft is in a first position, fluid flows into the pump chamber and one or more apertures through the piston shaft are sealed off by the post seal. When the piston shaft is in a second position, the piston engages a wall of the pump chamber and the one or more apertures are away from the post seal to provide a fluid path from the pump chamber to the interior of the hollow piston shaft and is dispensed through an output.

Abstract: Under-counter foam dispensing systems and refill units for under-counter mount foam dispensing systems are disclosed herein. An exemplary refill unit includes a container for holding a liquid, at least a portion of a liquid pump, a quick-connect air manifold for releasably connecting to a pressurized air source, an air passage to a mixing chamber and a liquid passage to the mixing chamber. The air inlet is in fluid communication with the source for pressurized air when the refill unit is mounted in the dispensing system and disengages from the pressurized air source when the refill unit is removed from the under-counter mount foam dispensing system.

Abstract: A refill unit for a foam dispenser that has an air compressor permanently attached to the dispenser is provided herein. The refill unit includes a liquid container and a body portion having a first end and a second end. The first end of the body portion is fluidly coupled to the liquid container. A liquid chamber is located in the pump body, the liquid chamber having an expanded state and a contracted state. An outlet nozzle is located proximate a second end of the body portion. A mixing chamber is located within the body portion. An air inlet is located through the body portion and is in fluid communication with the mixing chamber. A sanitary seal is located proximate the air inlet. The sanitary seal allows air to enter into the mixing chamber and prevents liquid from traveling out of the body portion through the air inlet.

Abstract: A filtration bag assembly may include an air permeable bag and a collar affixed thereto. The collar may include an opening that communicates with the interior of said bag and at least one panel that is movable to selectively obscure the opening. The collar includes a bottom surface and a pair of opposed tabs extending laterally from opposed lateral edges of the collar. A bracket is secured to the floor cleaning apparatus and includes a pair of opposed legs, that each includes a first ramp surface and a second ramp surface. During insertion of the collar into said bracket, the first ramp surface slidingly contacts the bottom surface and the second ramp surface slidingly contacts said tabs to move the collar upwardly into fluid communication with a nozzle.

Abstract: An upright vacuum cleaner is provided having a dirt collecting system with a downwardly pivoting lid for disposing of the collected dirt. The dirt collecting system has a latching arrangement for securing the pivoting lid into the closed position. A release member on the sidewall of the dirt collecting container is in operative engagement with a latching arrangement for releasing the pivoting lid from the closed position when the dirt collecting container is removed from the cleaner housing. The latching arrangement utilizes a slide member that traverses the underside of the pivoting lid. The slide member is biased into the latched position by a pair of resilient members. A pair of torsional springs are disposed in the hinges pivotally connecting the pivoting lid to the sidewall of the dirt collecting container to bias the pivoting lid into the open position when the release member is depressed.

Abstract: The cleaning apparatus includes a base portion for movement along the surface and a handle pivotally connected to the base portion. A recovery tank is removably mounted to the handle and has a front end. A lid covers the recovery tank and has an inlet opening for directing dirt and liquid into the recovery tank and an outlet opening located at the front end of the recovery tank. A suction nozzle is secured to the base portion and fluidly communicates with the inlet opening of the lid. A suction source fluidly communicates with the outlet opening for drawing dirt and liquid from the surface through the suction nozzle and into the recovery tank. A partition device is positioned between the outlet opening and the inlet opening and extends down within the recovery tank a sufficient distance to prevent the liquid from flowing from the inlet opening to the outlet opening.

Abstract: A cleaning apparatus for cleaning a surface in which cleaning solution is dispensed to the surface and substantially simultaneously extracted along with the dirt on the surface in a continuous operation is provided. The cleaning apparatus includes a base portion for movement along the surface and a handle pivotally connected to the base portion. A solution tank for supplying a flow of cleaning solution to the surface is removably mounted to a side of the handle. A recovery tank is removably mounted to the opposite side of the handle. A suction nozzle is secured to the base portion. A suction source is in fluid communication with the suction nozzle for generating suction to draw dirt and liquid through the suction nozzle and into the recovery tank.
