  • Patent number: 11464383
    Abstract: Aspects of the present invention relate to a recovery tank support structure for a surface cleaning device such as an extractor. The support structure partially encircles and supports the recovery tank removably mounted to a base in order to prevent any unwanted movement of the tank or its contents during operation of the extractor. The support structure creates a void for housing the recovery tank, wherein a locking mechanism may be employed to engage the recovery tank and secure it in position. An upper portion having a handle for propelling the extractor is pivotable about the base independent of the support structure thereby allowing a user access to a wide range of pivoting motion and maneuverability during extractor operation.

  • Publication number: 20220304535
    Abstract: Aspects of the present invention relate to a triggerless extractor surface cleaning device for cleaning a surface in which a cleaning solution is distributed to the surface and extracted using suction along with dirt and/or debris on the surface in a continuous operation as the extractor moves along the surface. The extractor further comprises an encoder positioned adjacent a wheel of the extractor for detecting a rotational direction and speed of the wheel to generate a signal. Based on receiving the signal, a controller controls operation of a valve to situationally distribute the cleaning solution to the surface depending on a forward rotation of the wheel and independent of user actuation of a trigger positioned on a handle used to propel the extractor along the surface. Distribution of the cleaning solution can be further optimized based on the detected rotational speed of the wheel.
