Abstract
An apparatus for first cleaning and thereafter rinsing a bathtub (10) by a cleaning liquid (60) and a rinsing liquid (61). Once the cleaning liquid has reached a predetermined level, the liquid is recycled via a suction extraction device (70) and is returned to the bath via a supply mechanism (11) disposed along the upper edge of the bathtub. Thereafter, the cleaning liquid is run off via a bottom outlet (13). The rinsing liquid (61) is supplied to the bath and recycled thereto via the suction extraction device (70) and the supply mechanism (11). A pump (40) is disposed to supply or discharge, via a conduit (23, 24), liquid from the bathtub. At least one (23) of the conduits is connected to the supply mechanism (11), and in addition control and regulation devices (50) are provided for starting and stopping the pump (40) and for adjusting the valve devices (41, 42, 43) to closed or opened positions for the supply of cleaning liquid or rinsing liquid to the bathtub.
