Sure Baracudda markets itself as having no moving parts, but the one part that does all the action also wears out on a yearly basis. If you ask me, it’s also a moving part, so their literature is pretty misleading.
If you’re budget allows spending over a grand, then the Polaris vac sweep 360 or 380 is most certainly the way to go. The only issue here is if your pool currently has a plumbing line going to the pool it can use. Without one, you’ll have to go the over deck route, which then is a hose to trip over, lying on the deck. That’s the only drawback.

These two cleaners are totally different in their collection and operation. The Kreepy uses suction side plumbing (debris to the pump basket and filter), the Polaris uses pressure side, with it’s own booster pump and it’s collection is a bag attached to the Polaris head. So check out these befor settling on a Dolphin Automatic Pool Cleaner.
