A filter base for receiving a complementary mating filter housing assembly. The filter base includes a base platform having fluid ingress and egress stanchions, and a wire harness assembly including a connector housing integral with or connected to the base platform for establishing an electrical connection between the filter base and the filter housing assembly. The wire harness assembly includes conductors extending between first and second connectors, with one or more resilient contacts provided on the second connector. The connector housing has an upper surface and an oppositely facing lower surface and is dimensioned to receive a first end portion of the one or more contacts. The contacts are flexible from a first position to a second position when a mating portion of the one or more contacts engages a mating connection surface of the filter housing assembly. The mating connection surface may be a circuit pad of a printed circuit board, wherein the contact mating portions are configured to be positioned in mechanical and electrical engagement with the circuit pads when the filter housing assembly is received within the filter base.

A bucket includes: at least two chambers which are flow connected to one another by at least one overflow channel. One of the chambers is a combined washing-out/centrifuging chamber for a cleaning device. One of the chambers is a water level-regulating chamber configured to regulate a water level in the washing-out/centrifuging chamber. The water level-regulating chamber contains a displacement body which is movable by a first actuating device.
