Couldn't keep my large pool so clean without it!

It has been a great addition to my pool cleaning. I used it about half the year in place of my Polaris 280 and was fairly impressed. Opening the pool for the first time this year it did very well, because it was a mess. Even though being covered it still had leaves and large debris that gathered in the deep corners. I got most of the large leaves and debris out before I started though. It took pretty much 4 hrs to get the majority of dirt and small debris. It even cleaned the floor as well. I cleaned it about 3 to 4 times during this period. It may have been able to get some of the large debris, but I didn't want to keep taking it out of the pool or possibly making it work harder than what it's designed for. PRO's: it runs off your electricity can use remotely with phone set and forget easily cleans CON's: not for larger debris not good for removing algae CONCLUSION: The Sigma surprised me, basically it's a plug and play, it was efficient and the cartridges' were easy to clean.

So easy to use and gets my pool very clean !! Love it I have had it about a year!!

Starting our second season with our Dolphin Sigma. I did a lot of research and it got great reviews. We have a 20 x 40 freeform pool with many large trees that are too close to the pool. and I'm very impressed with it's ability to vacuums pollen, tree debris etc.. I would definitely recommend the Dolphin Sigma!

Best pool vacuum I’ve ever had. My pool is cleaner than it’s ever been.

Purchased the Dolphin Sigma last year. Have used it now for over 12 months and it cleans our 16x35 foot free-form fiberglass pool magnificently. You can't go wrong with this unit, period.

I have to admit, it took me awhile to pull the trigger on the purchase of my dolphin pool vacuum. I lost count of the hours I spent vacuuming the pool in our small HOA community. I didn’t expect the vacuum to do such a thorough job. I like this vacuum so much I named her. Now, I drop Ariel into the pool and go about completing other chores. This pool vac is a life saver.
