I recently had a new 21ft above ground pool installed and im looking to purchase an automatic cleaner. Robots seem to be the best option but I feel like it might be overkill for a small above ground. So I'm stuck between a pressure side and suction side cleaner. I have a VS pump but don't mind bumping it up for a cleaning season. My other concern is that I have a DE filter and I don't want to be cleaning/recharging that more regularly because of the suction side cleaner. I may be over thinking this but that's what I do. Any help/opinions would be appreciated. These are the cleaners I'm looking at but I'm open to suggestions. Polaris vac-sweep 65, Zodiac MX6, or Dolphin Escape (or E-10).
