I have a pool blaster which I was happy with EXCEPT it left sand and small dirt particles behind. (I have a lot of granddaughters and glitter is a problem LOL) The microfilter bags are very good at picking up very fine sand and other particles. My pool company told me I would have to drain the whole pool and dry vacuum it but these new filters worked so well that will not be necessary. The bags are not very sturdy and wear out easily but at this price point it is easy to replace them. Very happy with this purchase
