A surface cleaning apparatus has an upstream air treatment member and a downstream cyclonic cleaning stage that includes a plurality of cyclones in parallel. Each cyclone has a cyclone axis of rotation, a first end, an axially spaced apart second end, a sidewall extending between the first and second ends, an air inlet, an air outlet, and a sideways dirt outlet. The surface cleaning apparatus also includes a dirt collection chamber and a dirt collection plenum.

A dishwasher in one embodiment is provided with a spray arm, and the spray arm is provided individually with areas configured to spray water to a first spray area and a second spray area, and sprays water to the first spray area to entirely wash objects to be washed accommodated in the dishwasher and sprays water to the second spray area to wash objects to be washed with remaining contaminants by applying a great impact on the object to be washed with remaining contaminants.

Provided is an autonomous coverage robot including: a chassis; a set of wheels; a plurality of sensors; and a mopping assembly including: a fluid reservoir for storing a cleaning fluid; a cloth for receiving the cleaning fluid, wherein the cloth is oriented toward a work surface; a means to move at least the cloth of the mopping assembly up and down in a plane perpendicular to the work surface, wherein the means to move at least the cloth of the mopping assembly up and down is controlled automatically based on input provided by at least one of the plurality of sensors; and a means to move at least a portion of the mopping assembly back and forth in a plane parallel to the work surface.
