Which replacement pool sweep
We have a Polaris 380 pool cleaner that is over a decade old. Our pool was just refinished with Wet Edge Pearl Matrix and when we put the pool sweep back in we noticed that it's wheels aren't working right. They jam and the sweep stops moving. We don't yet know if it is repairable, but I want to be prepared in case we need to replace it.
While at Leslies I noticed that there are now a lot more models of Polaris and another brand, Dolphin. Some claim to be robotic and I've got no idea what they mean by that.
Our pool is about 35,000 gallons and around 800 sq ft surface area. It is kind of t-shaped with the top of the T going from 11 ft to 5 ft deep and the base of the T is a shelf 2 1/2 feet deep. There are tall trees (redwoods and deciduous ones) within 10 feet of the back of the pool.
The shallow end being a step was a change made to the pool when we remodeled - before it sloped up from the deep end and was about 4' deep at its shallowest with not much area where I could stand since I'm short. We want something that will get up onto the shallow end and clean it.
Should we replace it with the same kind or get something different? Is the Polaris 3900 Sport (seems silly that that they call it that and model their newer models to as much look like sports cars as they can manage) any more reliable? We've had a number of repairs on the Polaris over the years.
Is there something that will work better? The guy at Leslies says that the robotic models cost less to run, but I'm concerned that they might not hold as much debris.
