Was the best thing you can buy for your pool. Drop in pool and watch clean. Pool in is brushed and vacuumed to perfection.

Jack Faessler - 5 Stars

The cleanliness of my pool has been greatly improved, and the amount of time that I must expend to maintain a clean pool has been minimized. Yours is an outstanding product: works as is demonstrated. It is in daily use here. Its ONLY detractor is the tendency for its power cord to tangle/kink with repeated use —which requires periodic manual detachment from the control unit, straightening it's cord and reattachment. A retrofit for that would be appreciated!

Miquel Abramowicz - 5 Stars

From the moment I unwrapped it I knew I'd love it. What impressed me the most was the filter baskets, with its removable sides. Compared to my old Dolphin, that used a bag, the I had to empty, wash and scrub, what a laborious pain it was. If I had to mention a deficiency, I'd list the fact that the clean cycle is too short, perhaps there's a longer cycle, that I'm unaware of. I did experience a problem with the filter panels, that started disintegrating about a year after I got, When I contacted Maytronics, they offered to replace them as a one time courtesy Kudos to them!

Pat J. - 5 Stars

I've had my Dolphin Quantum for a year now and absolutely love it. I run it year-round since I live in Florida. It performs beautifully and keeps the pool sparking clean. The only problem I have is that the cord attached to the robot doesn't swivel and you get a knotted, tangled mess. Otherwise it is a great investment.
