I have a Polaris pool sweep. It does a nice job and this is the third one I have had in 32 years. I have never had an issue with the sweep but I do take issue with the consumables. The mesh bag and the foam tip protectors wear out and from most pool supply places they are grossly priced. The mesh bag ranges from $25.00 to $45 for a mesh bag with a zipper. This bag is 100% compatible with my sweep and costs far less at $15.98 with free shipping (must purchase $25 at Amazon). It is the old style velcro bag instead of the newer zippered bag but it does the job for less money. A good purchase!
If reviewing a product, it may have been received free of charge. That will NEVER have a bearing on my recommendations.
