Still working

This was a little on the expensive side but for what it does it's worth it. No more hooking up the hose to the skimmer and putting strain on your pump. Just simply plug this one in and let it do it's thing. Really wished I would have bought one long ago. Make my life mush easier with pool cleaning. Only had it for one season so far so not sure how long it will last but we will see.
