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 supply means (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 means (11). The rinsing liquid is thereafter run off from the bathtub. The apparatus according to the invention includes the supply means (11) and the pump (40) which is disposed to supply or lead off, via a conduit (23, 24), liquid from the bathtub. At least one (23) of the conduits is connected to the supply means (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.</p> |
