ABSTRACT OF THE DISCLOSURE A multi-motor suction cleaner of the upright type having a power-driven rotary brush operated in the usual manner with a low-suction, high-volume airflow produced by a typical first motor-fan unit in the cleaner suction nozzle housing to carry out a usual floor, rug or carpet cleaning operation. The cleaner is converted to efficient off-the-floor cleaning merely by selectively uncovering an opening in a closed suction chamber carried by the cleaner containing a second motor-fan unit pro- ducing high-suction, low-volume airflow. A converter member mounted on one end of a typical flexible attachment hose is inserted in the uncovered opening. This automatically energizes the second motor-fan unit. The selective and alternate opera- tion of the two motor-fan units provides a single cleaner that can carry out most efficiently every cleaning operation here- tofore requiring both a canister and an upright cleaner to per- form. In addition, the cleaner is convertible to blower opera- tion by connecting the converter member to a blower receptacle also provided for the closed compartment.
