A clothes care apparatus includes a cabinet, where a first chamber is defined in the cabinet; a first door configured to open or close the first chamber, where a second chamber separated from the first chamber and configured to accommodate a garment is defined in the first door; a second door pivotally coupled to the first door and configured to open or close the second chamber; a switchable mirror arranged on the second door and operable in a mirror mode or a transparent mode; a spot cleaning device arranged in the second chamber to partially clean the garment accommodated in the second chamber, and movable in the second chamber; and a controller configured to control the switchable mirror and the spot cleaning device.

A system comprises a support, typically part of dishwashing machine or clothes washing machine, having a plurality of piezoelectric transducers. Each transducer can have a cylindrical housing with a water inlet along a side surface of the housing. The transducers can also comprise a lens and a piezoelectric material with electrodes configured to couple to a power supply.
