When using a hose with an on/off switch on the handle, the central vacuum unit will automatically start when the hose is connected to one of the wall inlets. While in operation, the vacuum unit can be turned on and off using the rocker switch on the handle without disconnecting the hose.

A special advantage of the GV hose is that both the handle and the hose cuff can be rotated 360°.

Note: hoses with a switch only work if the wall valves on the inside are provided with 2 metal contacts (pin-jacks). New wall inlets have this as standard.
