Abstract
A filter unit capable of receiving a cartridge-type filter element is provided for use in-line with a suction-type pool cleaning device. The unit has an elongated housing with intake and outlet ports at opposite ends. The intake port may be connected via a hose to a pool cleaning device and the outlet port to a suction port in the pool circulation system. The unit can use a filter cartridge with an element that offers a filtration coarseness somewhere between that of the system filter and a strainer element. The housing may be adapted to receive a strainer basket in place of the filter cartridge and thus serve as a conventional leaf-trap.
