发明名称 CONCEALED AUTOMATIC POOL VACUUM SYSTEMS
摘要 <p>A vacuum pool-cleaning storage system that is housed in the side of a swimming pool substantially below the waterline. The pool vacuum cleaner automatically deploys to clean the pool when the central pool vacuum pump is activated, and automatically retracts to a stored position when the central pool vacuum pump is turned off. The system is adapted to store the vacuum hose in a substantially linear tube located substantially underground. A reel-type hose storage embodiment is also disclosed. The system is preferably powered by vacuum pressure generated by a water circulation pump of the pool plumbing system.</p>
