This is mainly because to the straightforward construction and one moving part.
The pre-filter is fairly simple to maintain but does not self-clean.
The debris can be removed by opening the sliding valve.
The stainless steel filter element in the UltraSieve pre-filters never has to be changed.
The water falls directly through the sieve because of the triangular stainless steel rods at a 7° angle, but the debris is left behind.
The fact that the material is actually removed from the water circulation is a significant benefit of this theory.
Because waste items are no longer polluting the water, this is very advantageous for the quality of the water.
