VACUUM CLEANER APPARATUS AND HOSE THEREOF
Abstract:
A vaccum cleaner has a hose (10, 30, 30') that is retractable in length by the application of reduced pressure from the vacuum cleaner. After use, the free end (14, 21, 33) of the hose is occluded so that pressure falls within the hose and it is retracted in length. The hose is restrained in its shortened length before suction is turned off. The hose in its retracted state may be stored on or off the vacuum cleaner.
