Patent number: 11896176Abstract: 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.Type: GrantFiled: June 13, 2022Date of Patent: February 13, 2024Assignee: TECHTRONIC FLOOR CARE TECHNOLOGY LIMITEDInventors: Patrick Diana, Douglas M.

Publication number: 20230218130Abstract: A surface cleaner includes a suction source that generates a suction airflow to draw liquid-laden air along a fluid flow path from a dirty air inlet to a recovery tank. The recovery tank includes a chamber for storing liquid, an inlet along the fluid flow path, an outlet aperture along the fluid flow path, and a float having an indicator. An inflow path upstream of the inlet connects the dirty air inlet to the recovery tank. The float moves between a first position spaced away from the outlet aperture allowing air to exit the recovery tank along the fluid flow path, and a second position adjacent the outlet aperture obstructing the fluid flow path. The indicator is visible to a user when the float is in the second position.Type: ApplicationFiled: March 16, 2023Publication date: July 13, 2023Inventor: Douglas M. Rukavina

Patent number: 11690492Abstract: A floor cleaner includes an electrically powered component and a switch. The switch includes a button including an actuator surface. A fluid channel is formed by a fluid collection surface disposed below the button and an outer channel wall extending upwardly from the fluid collection surface, the fluid channel having a fluid outlet. A projection of the button is received in an inner button aperture formed by an inner wall extending from the fluid collection surface forming a bushing around the projection. The inner wall inhibits flow of fluid from the fluid channel through the inner button aperture. The outer channel wall surrounds the aperture wall such that fluid entering the body between the perimeter of the button actuator surface and the aperture wall is collected by the fluid channel and directed to the fluid outlet.Type: GrantFiled: April 23, 2021Date of Patent: July 4, 2023Assignee: Techtronic Floor Care Technology LimitedInventors: Douglas M.

Patent number: 11464383Abstract: 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.Type: GrantFiled: December 14, 2018Date of Patent: October 11, 2022Assignee: TECHTRONIC FLOOR CARE TECHNOLOGY LIMITEDInventors: Douglas M.
