ABSTRACT:
The flexible hose of an industrial scale vacuum cleaning apparatus is wound upon and unwound from a drum by a reversible motor which drives four rollers tangentially engaging the hose at a point between the drum and the vacuum intake. The rollers preferably comprise small pneumatic tires inflated to a low pressure and the motor control means are located on the operator's handle connected to the vacuum intake head.
