Patent attributes
An improved pool vacuum includes a filter cone and poppet valve combination which enables quick drainage of water which has passed through and been cleaned by the cleaner's filter. A charging circuit is provided with isolation so that the pool vacuum can be used in an electrolytic environment without battery drainage. A combination charger and hang bracket enables the pool vacuum to be stored in a vertical position to both drain and charge simultaneously. An interstitial open exhaust gap between a rear body and nose-cone shaped front section provides a low pressure drop free exhaust area for an impeller. An optionally obstructed bottom gap portion helps to produce a net downward thrust to assist in using the vacuum in deep pools from a long pole structure.
