Abstract
Disclosed are new features relating to a brush-supported carpet cleaning machine of the type having counter-revolving brushes. Such features include a new handle mounting and latching arrangement which simplifies handle mounting and de-mounting, which helps support the weight of a handle-mounted vacuum pod and which promotes a high degree of machine self-propulsion. The pod is attached to the machine handle by a novel gudgeon-and-pintle mechanism. Such features also include a new support device, preferably brush-mounted, which helps prevent the machine shroud from snagging carpet if the machine should 'wallow' or 'yaw' in operation.
