Abstract:
The present invention provides unique portable or stationary hose retraction systems in a single compact unit having a hose, a chamber or plenum for storing the hose, a vacuum source, and a unique valve mechanism attached to the chamber or plenum for holding the hose in place while it is being used, and releasing the hose to allow it to be extended by the user or retracted by the system using the vacuum source. An optional debris collection chamber with filter may be provided adjacent to the vacuum hose chamber, such that the vacuum source draws air through both the debris collection chamber and through the vacuum hose chamber.
