ABSTRACT:
A pool skimmer to operate independently of a pool filter pump. A pool skimmer has a bucket assembly similar to pool skimmers that use the filter pump to create a suction to draw and hold surface floating debris inside the pool skimmer where the debris can be removed from the bucket assembly and emptied. However, instead of using the pool filter pump, a sealed electrical pump assembly uses a rotatable magnetic assembly inside the sealed pump body. A magnetic impeller fits within the pump body and rotates in response to rotation of the magnetic assembly inside the sealed pump body. This creates a water flow forcing water out of the bucket assembly in contrast to using a filter pump to suck water through the bucket assembly as in conventional technology. Because each pool skimmer operates independently of others and of the filter pump, they may be located without regard to filter pump efficiencies. Moreover, the suction created is not enough to create a health hazard for users, especially small children.
