  • Patent number: 11365132
    Abstract: A control system for a water treatment apparatus that includes a control valve assembly having a servo chamber in which a stationary port defining signal ports is located. A regeneration control disc sealingly engages and rotates on a planar surface of the port disc and selectively communicates fluid signals to water pressure operated components within the control valve. An electric motor located in a dry chamber is operatively coupled to the regeneration control disc and rotates the disc during a regeneration cycle. An encoder coupled to the control disc monitors its position and movement. A turbine assembly monitors water treated or to be treated and is electronically coupled to a regeneration controller. A sensor emits pulses related to rotation of the usage turbine and communicates these pulses to the controller which uses this information to determine when a regeneration is needed whereupon the drive motor is appropriately energized.

  • Patent number: 9271619
    Abstract: A floor care appliance is provided for cleaning bare surfaces such as tile, marble, linoleum and wood. The floor care appliance is comprised of a base portion having a suction nozzle and a brush block having a plurality of vertical axis rotary agitators for cleaning bare floors. The rotary agitators are driven by an independent motor for agitating the floor surface. With the addition of an accessory hose and tools, the cleaning utility can be expanded to areas wherein the suction nozzle cannot normally reach such as behind the toilet, shower walls, and the grout between tile. While used in the capacity for cleaning bare floors, the floor care appliance can be moved between three modes by a rotating a member located on the upper housing. The first mode is dry mode, the second mode is wet scrub mode and the third mode is wet pickup mode. The accessory tools are stored in an accessory caddy that is placed freestanding over the suction nozzle and in front of the housing.

  • Patent number: 8635740
    Abstract: An extractor cleaning machine includes a base or foot having a distribution nozzle and a suction nozzle. A suction source fluidly communicates with the suction nozzle, and a distributor fluidly communicates with the distribution nozzle. The distributor delivers cleaning fluid to the distribution nozzle and has first and second non-zero operating speeds. A first manually operable actuator associated with the distributor changes the distributor from the first operating speed to the second operating speed. The distributor also includes a third non-zero operating speed, and a second manually operable actuator associated with the distributor changes the distributor from the second operating speed to the third operating speed.

  • Patent number: 8516655
    Abstract: A vacuum cleaner includes a floor engaging portion and a handle portion pivotally mounted to the floor engaging portion. The handle portion includes an input device. An agitator is rotatably mounted in the floor engaging portion to agitate a floor surface being cleaned. A first motor has an output shaft and an agitator belt selectively drivingly connecting the motor to the agitator. A tensioning arm pivotally mounts to the floor engaging portion for motion between an agitator-on position in which the tensioning arm engages the agitator belt, to place the agitator belt under tension whereby the agitator belt drives the agitator, and an agitator-off position in which the tensioning arm does not engage the agitator belt, to place the agitator belt in a slack condition whereby the agitator belt does not drive the agitator.

  • Patent number: 8028370
    Abstract: A cleaning machine for cleaning a surface is provided. The cleaning machine includes a base assembly that moves along the surface and a liquid distribution system associated with the base assembly for distributing the cleaning solution to the cleaning surface. A suction nozzle assembly is mounted to the base assembly and includes a front nozzle portion and a rear nozzle portion. The front nozzle portion defines a fluid flow path having an inlet opening and an outlet opening and the rear nozzle portion defines a fluid flow path having an inlet opening and an outlet opening. A suction source is in fluid communication with the suction nozzle for applying suction to draw the cleaning solution and dirt from the surface and through the suction nozzle assembly. The fluid flow path of the front nozzle portion is closed in response to the base assembly moving in one of the forward direction and rear direction.

  • Patent number: 7725223
    Abstract: A self propelled upright vacuum cleaner is provided with a Hall effect sensor to provide a Hall voltage that varies according to the position of a handgrip maintained by the vacuum cleaner. A microprocessor generates a PWM control signal to control the movement of the vacuum based on the magnitude of the Hall voltage with respect to various response characteristics, including a non-linear logistic function. As such, the vacuum cleaner imparts a user-friendly responsiveness to the user during the operation of the vacuum cleaner.

  • Publication number: 20090165822
    Abstract: 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.
