Abstract

A surface cleaner includes a suction airflow, a base air inlet, a housing, a wand coupled to the housing, a wand housing, a handle, a hose coupled to the handle, a first airflow path, a second airflow path, and a valve moveable between a first position and a second position. In the first position, the suction airflow is directed along the first airflow path and the suction airflow along the second airflow path is inhibited. In the second position, the suction airflow is directed along the second airflow path and the suction airflow along the first airflow path is inhibited. The valve moves from the first position to the second position in response to the handle being uncoupled from the wand. The valve moves from the first position to the second position in response to the wand being removed from the wand housing.

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.

The supply tank having an inlet opening defining an inlet opening width and a fluid disposed therein. A water soluble package includes a cleaning solution disposed therein and is inserted within the supply tank to combine with the fluid disposed therein to form a cleaning fluid. A distribution nozzle is in communication with the supply tank and disperses the cleaning fluid towards a ground surface. The package has an unfolded dimension defined by a first width that is larger than the inlet width, a height defined orthogonal to the first width, and a thickness defined orthogonal to the first width and the height. The package folds from the unfolded dimension to a compact size having a folded dimension defined by a second width that is smaller than the inlet opening width.

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.
