Abstract

The present invention provides a washing machine (10) including an outer bowl (14) and an inner moving bowl (12) to hold clothes to be washed, the inner bowl (12) including at least one aperture (30, 32, 36) therein to allow water to pass from the inner bowl (12) to the outer bowl (14), the machine (10) including at least one pump (16), and an outlet (18) from the at least one pump (16) which will direct water from the outer bowl (14) to the inner bowl (12), the at least one pump (16) being adapted to pump water from the outer bowl (14) to the inner bowl (12) so as to maintain the depth of water in the outer bowl (14) less than the depth in the inner bowl (12).
