Abstract:
An automatic pool vacuum unit is connected to a skimmer housing by a vacuum housing fitted in an inverted U-shaped opening in the skimmer weir, open to the bottom of the weir. In order to avoid interfering with normal pivoting of the buoyant weir by the vacuum housing, the housing in planes at right angles to the pivotal axis of the weir has upper outlines that are arcuate about that axis, and the vacuum housing has an outline matching the outline of the inverted U-shaped opening in planes through the weir pivotal axis, so that the vacuum housing substantially fits and substantially seals the weir opening as the weir pivots. A removable cover over the debris-collecting basket in the skimmer housing has an opening connecting with the vacuum housing and an adjustable opening for skimmer water spilling over the top of the weir. The vacuum housing is removably secured to the cover to facilitate removal of the debris collecting basket.
