I bought this model at the first of the year and have used it several times since. We are in the spring water oak leaf shedding season here in SW Georgia and our pool, which is open year round, gets a lot of debris. This cleaner works very well. It has a big debris collection box which is one reason I bought it. Following storms, it has been filled on two occasions this spring. So far, so good, I could not be happier. Its has a 2 year warranty, and I hope I don't need it.
