摘要:
A stacked looped hose rack for upright vacuum cleaners provides a top hose receptacle, a bottom hose receptacle, and an intermediate hose receptacle, all three attached to the handle assembly of the upright cleaner. The top hose receptacle is rotatable to provide for a quick dump or release of the hose spirally wrapped around the top and bottom receptacles, and through the intermediate one. The bottom receptacle is in the form of a spool, the top receptacle is in the form of a generally elliptical spool, and the middle receptacle is provided with a pair of channels in H-type configuration to receive the hose as it passes therethrough.
