  • Publication number: 20250213090
    Abstract: A surface cleaning head may include a fluid distributor configured to distribute a cleaning fluid, an agitator configured to absorb at least a portion of the distributed cleaning fluid and to agitate debris on the surface to be cleaned, a fluid stripper configured to remove, from the agitator, at least a portion of the distributed cleaning fluid absorbed by the agitator, a debris container, and a removable cover. The debris container may include a solid debris chamber and a fluid debris chamber. The removable cover may include a fluid catch plate configured to transfer at least a portion of the cleaning fluid removed from the agitator by the fluid stripper to the fluid debris chamber, the fluid catch plate being configured to selectively transition between an in-use position and a cleaning position when the removable cover is removed from the surface cleaning head.

  • Publication number: 20250151962
    Abstract: In general, the present disclosure is directed to a hand-held surface cleaning device that includes a relatively compact form-factor to allow users to store the same in a nearby location (e.g., in a drawer, in an associated charging dock, on a table top) for easy access to perform relatively small cleaning tasks that would otherwise require retrieving a full-size vacuum from storage.

  • Publication number: 20240423437
    Abstract: The present disclosure is generally directed to vacuum tools. In one example, a first wet/dry crevice tool is provided that can be coupled to a vacuum source and a cleaning fluid source. The first tool includes a vacuum orifice and a cleaning fluid nozzle assembly coupled to a cleaning fluid actuation mechanism to controllably deliver cleaning fluid to a target area to be cleaned. The vacuum orifice and the cleaning fluid nozzle assembly are configured to sealingly interface with another cooperating tool. The first tool includes latching mechanisms and tolerance rails to enable secure coupling of the first tool to another cooperating tool, for example a liquid containment tool.
