Some adjustments to make in my case, lighten the nose (part of or freewheels direction) for example, it works very well in an above ground Intex (750 x 350), with a pump Intex 0,9cv.
The cleaner works by the Venturi effect, thus connects the RETURN jack of the filtered water, so no waste sand filter level while remaining on the integrated filter vacuuming. And it does, proceeds received yesterday, hours and presto, it's clean.
Simple and rugged construction, not too much anxiety on longevity, everything is easily disassembled, it's very well done, intelligent, in short, it inspires confidence, and for now, that the merit quite. I recommend no problem !!
