    摘要： An adapter is connected to a hose cuff on a vacuum hose for connection with two different inlet valves of a central vacuum system. The hose cuff may connect with a primary inlet valve and when the adapter is connected to the hose cuff, the adapter enables the vacuum hose to be coupled with a secondary inlet valve that is different from the primary inlet valve. There is a conductive material on the adapter that completes an electrical circuit by contacting two metal conductors or pins in the secondary inlet valve to activate the central vacuum system when the adapter completes the circuit.

    摘要： A vacuum cleaning system including a robotic unit including a traction arrangement that defines a ground plane, and a docking interface for receiving a handheld vacuum cleaner. The docking interface defines a suction port, an electrical port, and a predefined interface geometry. The docking interface is reconfigurable from a first configuration for engaging with a first handheld vacuum cleaner, and a second configuration for engaging with a second handheld vacuum cleaner which is different to the first handheld vacuum cleaner. Conveniently, the system includes a robotic unit or module that is dockable or engageable with multiple handheld vacuum cleaners, thus allowing some flexibility with the type of machine that they are able to use with the robotic unit. This provides a cost effective solution for the user, because if the user upgrades their handheld vacuum cleaner that new handheld vacuum cleaner can still be used with the robotic unit.

    摘要： A cleaning head (100) of a suction cleaning apparatus (10) comprising a brush head (140) configured for agitation cleaning during suction cleaning and the suction cleaning apparatus (10) comprising the cleaning head (100) are disclosed. The cleaning head (100) comprises a tubular housing comprising an inlet portion (122) including an inlet nozzle (132) which extends along a centre axis defining an axial direction, an outlet portion (124) having an outlet end, and an intermediate portion (126) interconnecting the inlet portion (122) and the outlet portion (124); the brush head (140) comprising a plurality of bristles (142) arranged to form a bristle skirt having a forward end; and a motor (152) configured to drive the brush head (140) to rotate or oscillate about a rotation axis.
