We don't have much experience with Pool Man yet. So far so good. I would just make one small recommendation. When treating the pool for imbalance and you're not suppose to swim in it for 24 hours, I would tape the notice to the back patio door.
My husband did not see the notice left on the outside patio table (plus he hates to read) so he went swimming before he should have. I came home, read it, and had to scold him :)
Diligent and caring service. Recently, there has been some issues with new hires, but management took care of it quickly. I've used them (Clearly) since I bought my house in 2010. The previous owners used them. Willing to teach and help out.
