Abstract: A pool/spa skimmer includes a housing, a face plate, and a flexible weir gate. The housing and plate are dimensioned to allow water to flow in a vertical column. The interior of the housing has a curved wall so that when a column of water passes through the open gate and into the housing, a whirlpool effect is realized. A vertical filter cartridge is mounted on a rotational bearing so that it can spin about its axis. The inlet of a pump is coupled to the cartridge via the bearing and is also coupled to a second water inlet via a vacuum operated valve. When the filter is clean, water is drawn through it and the filter spins about its axis due to the whirlpool effect. When the filter reaches a threshold dirt covering, water is no longer drawn through it and the vacuum operated valve.

Abstract: A sound transmission assembly and illumination system for a tub, spa, pool, bath, or shower includes an electronic audio speaker or sound wave-guide. When the sound wave-guide is used, a source of sound waves, a sound wave distributor, and one or more sound wave guides transmit the sound waves to one or more speaker-like orifices in the spa housing or head rest. The wave guides are typically conduits through which sound waves can be transmitted. The orifices typically include some form of perforated cover and may include means for providing sound attenuation. In one embodiment, the sound waves are transmitted to two speaker-like orifices in a head rest such that a stereo sound system is provided for the bather. The head rest may include one or more light-transferring resilient inserts and a light source which illuminates the inserts, for example, a LED-type light source. Also, the speakers, insert, and light source may be incorporated into a single assembly adapted for mounting beneath a head rest of a spa.
