The pool brush was purchased for a small 3m pool. But it's okay, because the cost is manageable. For larger pools a bit should be used, or you have to sometimes take a day off, because it takes a bit längerm until you have it all together. But all in all the pool was clean and what was then stirred up, you could get to the landing net or skimmer from the water. The 1.2m long extension tube is a little "kläpperig" in the handling, and acts as if it breaks off soon. Here perhaps a broomstick will have to provide a replacement service. The commercial "Gardena coupling" fit it and the grass-catcher is easy to clean under running water. Need to get the 3m pool clean (90%) you ever expect 90min, because you really get pretty slow.
However, since it takes away from me some of the work and the price is also reasonable, there 4 stars.
