1. A central vacuum cleaning system comprising:
- (i) a vacuum source including;
a motor within a motor housing,a receptacle extending from the motor housing for receiving dirt, anda motor control circuit including a variable speed controller for adjusting a speed of the motor;
(ii) one or more valves;
(iii) conduits for connecting to the vacuum source to the valves;
(iv) a handle to be held by an operator, a flexible hose for releasably connecting the handle to one of the one or more valves, and a cleaning attachment connected to the handle, such that when the motor is activated during use of the system, dirt is drawn by a vacuum created by the vacuum source through the attachment, handle, hose, and conduits, and into the receptacle;
(v) a user display at a display location on the handle for displaying information about an operating condition of the vacuum source;
(vi) a user input interface at an input location on the handle for adjusting an operating speed of the motor control circuit;
(vii) a communications system to transfer control signals from the user input interface to the variable speed controller of the motor control circuit to adjust the speed of the motor wherein the communications system comprises an RF wireless transmitter in the handle, and an RF wireless receiver at the motor control circuit.
