Abstract: Disclosed herein is a pool cleaning device having filtering and pumping capabilities. Some embodiments of the disclosed device can be unencumbered by hoses, cables, and the like when in use in the pool. The device may be buoyant and can be configured to float at or just below the surface of the water. The device can comprise a strainer, a pump, a housing for the strainer and pump, and one or more floatation devices. Such a design may allow for a floating skimmer and pump with no need for installation in a side wall. In some embodiments, the device can further comprise a pre-filter. For example, in some embodiments, the strainer and filter can remove large objects and particulates, respectively, before the water passes through the pump. As disclosed in some embodiments, various components of the device may be removeable and replaceable to extend the lifetime of the device.

Abstract: The invention relates to a filter cartridge for insertion in a filter housing of a fluid filter, comprising: a filter material configured to filter a fluid flowing therethrough from a raw side to a clean side of the fluid filter during operation of the fluid filter; and a filter-cartridge-side radio module configured to move, during operation of the fluid filter, according to the pressure difference between the raw side and the clean side of the fluid filter, which pressure difference depends on the degree of contamination of the filter material, and to communicate, in order to ascertain the degree of contamination of the filter material, with a housing-side radio module of the fluid filter, the distance (A) of which housing-side radio module from the filter-cartridge-side radio module varies upon movement of the filter-cartridge-side radio module.
