  • Patent number: 11751735
    Abstract: 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.
