The subject device of the invention is electric and used for cleaning, especially for washing and waxing cars. The main characteristic thereof is to spray cleaning solution, wash and aspirate the removed dirt and store same. The first, tri-functional operation is performed by the head, comprising a brush with a preferably circular cross-section wherein the scrubbing bristles (1) in the frontal view of the drawn example form a circular crown; interspersed between said bristles are the pipes for spraying the washing solution (3), which are channelled from the pipe (4) which together with the wider cross-section aspiration pipes forms the barrel and in the figure exits in the centre. Said barrel joins the head to the handle. The interior volume, limited by the scrubbing bristles (1), the face (2) of the head bearing said bristles and the surface for cleaning form a chamber wherein washing and aspiration take place. If these limits also are also taken to include the mouths of the spraying and aspiration conduits, this completes the head washing-aspiration system, which is the main basis of said tri-functional operation: spraying the cleaning solution, washing and aspirating. When cleaning begins the volume stored by the sac containing the cleaning product is full and therefore expanded and that containing the waste product is folded; as cleaning progresses the volume of the former reduces, it folds in on itself and the volume of the latter begins to unfold and expand, for both are flexible and impermeable. Both sacs are also extractable for replacement purposes. |
