摘要： The present invention provides unique portable or stationary hose retraction systems in a single compact unit having an elongated hose, a chamber or plenum for storing the hose, a primary vacuum source for creating suction in the hose, and a secondary vacuum source for retracting the hose into the chamber. Embodiments may include one or more switches located at a distal end of the hose for controlling the primary and secondary vacuum sources. Other embodiments include a movable robotic unit with a proximity generating signal at the distal end of the hose, whereby the robotic unit may withdraw the hose as needed during use, and the secondary vacuum source may retract slack in the hose during use, or may retract the entire hose and the robotic unit after use.

摘要： A cleaning apparatus includes an end cap assembly for use with an agitator. The end cap assembly includes a stationary end cap, a rotating end cap, and a fragmentor. The stationary end cap is secured to and stationary with respect to a housing of the cleaning apparatus. The rotating end cap is coupled to the agitator and rotates with the agitator relative to the housing. The stationary and rotating end caps define a gap extending radially inward therebetween. The fragmentor is disposed within the gap and is configured to break debris which enters the gap into smaller pieces. The fragmentor may be disposed on a surface of the stationary end cap facing towards the rotating end cap and/or on a surface of the rotating end cap facing towards the stationary end cap. The fragmentor may include a cutting blade and/or an abrasive surface.

摘要： A surface cleaning head includes dual rotating agitators (e.g., a leading roller and a brush roll) and a removable cover for covering a top of the agitators and allowing access to the agitators from a top of the surface cleaning head. The dual agitators may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The brush roll may be located in a brush roll chamber and at least partially in an opening to the suction conduit. The leading roller may be positioned adjacent to and in advance of the suction conduit opening such that the leading roller engages debris and moves the debris toward the brush roll and the opening. The leading roller may be removable from the housing and held in place by the removable cover. The cover may be coupled using isolated latching mechanisms.
