Okay everyone recommends the Dolphin robotic cleaners. We are in Winter Haven, Florida. We went to look at these today and could not find a single Dolphin in any pool stores in our area. Here is what we are looking for. We just spent 40k having our pool and patio remodeled and we want to keep it clean and stain-free. We have a stonescapes mini finish, a 14X30 rectangular sports pool. We have had several pools through the years and have taken care of them ourselves but now we are in our 70’s and we would like a pool cleaner that cleans the walls and waterline well so we don’t have to work so hard! Our drain sticks up a bit and we need a cleaner that doesn’t get stuck on it, as well as one that does the walls and waterline tile very well and is reliable. Our pool is caged so we don’t get many leaves but we do get lots of very tiny bugs and sand (Florida) so we need a micro-fine filter type that is easy to clean out. I have no idea which Dolphins are newer or older models? Online I was looking at the M600, the Explorer 70 and the Active 60, but maybe we are missing some? We will need one that has a caddy or will need to buy that separately. I called Maytronics and they told me the M600 is only sold in stores, not online, but I cannot find it in stores? Does anyone have any good recommendations for us?
