ABSTRACT:
This invention relates to a vacuum cleaning appliance which is convertible to act both as an upright type cleaner or a cylinder type cleaner.
The main air passageway through the appliance includes a motor driven suction fan unit and a valve device which is operable to connect the passageway either with an air inlet in a carpet engaging section or with an air inlet in a socket for receiving a cleaner head in the form of a hollow pipe which is connected with the socket by a flexible hose. The pipe slides telescopically within the flexible hose so as to engage within the socket and to act as a handle. When located in the socket the pipe operates the valve device to connect the air passageway with the carpet engaging section.
