So far it is working very well. The path it takes in the pool does not cover the whole thing in 1 round so we have to do it at least 2X. But it picks up even the tiniest particles. We are happy with it so far. To my understanding the filters are very expensive but we are washing it out and reusing until we have to replace.
It does a good job vacuuming and does some climbing. Very heavy though for a 70+ female. I do like being able to clean the vacuum from the top instead of the bottom.
