Abstract
An auxiliary vacuum device for a central vacuum cleaning system is location specific and comprises a housing mountable externally on an inlet of a mounting plate of the system, a dedicated flexible concertina hose is provided on the device and a cleaning tool mounting probe is registrable with a docking station. With the probe docked in the docking station the device is in the ‘off’ position and with the probe removed therefrom the device is in the ‘off/standby’ mode. A push on/off button is used to complete the procedure for starting the system and for stopping it in an ‘off/standby’ mode.
