A dirt collecting system for a vacuum cleaner includes a dirt cup formed with a coarse particle separation chamber and a fine particle separation chamber separated by an apertured wall. Coarse dirt particles directed into the coarse particle separation chamber are prevented from entering the fine particle separation chamber by the apertured wall. The apertured wall is removable from the dirt cup and is cleaned upon removal by a cleaning element. A fine particle filter is located in the fine particle separation chamber for filtering fine particles. The fine particle filter is cleaned by rotating a knob located in the dirt cup lid so that the pleats of the fine particle filter is brushed past a wiper element.

A vacuum cleaner includes a pivoting rollered link which insures proper belt tensioning for the agitator belt of the cleaner. This link is abuttingly moved to disengaged non belt tensioning position by engagement of it by the cleaner handle as the handle is moved to upper, storage position.

Vacuum cleaner belt drive release

A vacuum cleaner having a belt driven rotating agitator is provided with an indicia containing rotating dial, directly driven by one of these moving translating or rotating parts, to thereby indicate a problem or performance goal existent in one of them.

Cleaner with performance indicator

A cleaner suction nozzle is provided in which provisions are made for a nozzle height elevation arrangement and a hose conversion valve arrangement. The hose conversion valve arrangement works in conjunction with the nozzle height elevation arrangement so that the suction nozzle can be elevated from the floor to disengage the cleaner agitator and then hose conversion of the cleaner can occur almost simultaneously.

The structure comprehends a power transmission for a power drive cleaner where the clutching arrangement is on the output shaft that provides a direct geared drive to the wheels.
