Abstract
A remote control system for actuating a central vacuum system from a remote location such as a vacuum cleaning hose handle without the use of a separate, dedicated system of control wires. In a preferred embodiment, a small, lightweight FM radio frequency signal transmitter is installed in the hose handle and the signal is conducted along the household current 60 Hz wires running through the vacuum cleaner hose and wand for the purpose of providing electrical current to power sweeper brush motors. The piggybacked control signal requires no additional conductor wires, such as the low voltage wiring of conventional control systems, thereby saving weight and costs. The control signal travels along the power supply wires running the length of the vacuum hose, which are preferably covered by a sleeve, such as of cloth or plastic, then through a standard plug into a standard electrical outlet. A receiver located near the central vacuum cleaner system receives the control signal from the house wiring and processes it to start or stop the central vacuum system main motor.
