ABSTRACT:
A swimming pool vacuum apparatus as described in the U.S. Pat. No. 3,443,264 can be improved by providing a plate holding an outlet nipple from the container of such an apparatus on the bottom of the container so that the position of the outlet nipple can be varied or changed by changing the position of the plate. The lid in such an apparatus is improved through the use of a peripheral groove on the lid facing the top of the container containing an O-ring which fits against the container so as to form a seal with it. Preferably spacers are provided limiting the amount that the O-ring can be compressed and holding the O-ring within the groove.
