Purchased last season included 2 filter types which has been very beneficial based on size of the particles which need to be removed. Most of the year using the standard filter is adequate but having the filter which removes dirt/sand works perfectly when fields are being tilled around our home. Climbes the wall and scrubs just above the waterline so no need for additional cleaning. We have a large L-shaped inground pool with a tanning ledge and this purchase saved us hours of cleaning. A minor inconvenience, It is unable to clean/climb the steps to the tanning ledge so we brush them regularly and that worked just fine.. We have a vinyl-lined saltwater pool and this robot kept it sparkling clean. After one season of use we lost a couple of nubbs from the roller bar so will be calling for a replacement. Will update review once I speak with customer service about the roller bar. At this point I would highly recommend the product but at this price point expect no degradation of quality for years.

I originally bought this because I needed a better vacuum for the pool and wanted to spend less time cleaning it and more time in the pool. During the spring my pool water would turn yellow due to pollen and I had to backwash a ton. Turns out the Dolphin was picking up all the pollen and small dirt and leaf particles that were getting In the pool. After I bought this I never had to backwash the filter again due to pollen. During the fall tons off leafs were falling in my pool. The dolphin even picked up the leafs fell to the bottom of the pool that I wasn’t able to skim out in time. This was a costly vacuum but well worth it in my option. Just take care of it, rinse the filters often and it will keep working and it will take care of your pool for you. FYI- I bought the stand and the cover for it, in hopes that it would last longer.

I was able to connect my app with wi-fi once, but each time I get on the app, it tells me I am not connected to Wi-Fi and fails to connect despite a very strong signal. As a result, I have to manually go out to the pool and turn the product on daily. Since it gets stuck on the steps and stays there, I can only use it when I am home to “baby sit” it to keep it from damaging the surface of my pool when stuck. Despite two calls to customer service, I have received no help. They tell me the app has bugs and is being trouble shooted, but no timeline for fixes. I paid way too much for this product to have to turn it on each day and then to sit and watch it!!! I really only need it to run about 30 minutes each day, but support said it has to run for two hours. I only have another week to get this fixed, otherwise I will have to return for a full refund. If Maytronics can’t help me, I will never order another Dolphin. If I have the time to baby sit the unit, I can just brush and vac myself! But I don’t have the time and also don’t want to do it myself. Just call me Extremely Frustrated with this app and product!

I’m extremely disappointed with this app. After spending quite a bit of money on said vacuum for my pool that I am supposed to be able to start and control from my phone I am unable to do so. I can’t even get my phone to sign into the app most of the time let alone be able to start the dolphin up to so it’s job. Then I have to babysit the vacuum once it’s in the pool because I can’t control it. I’m also having issues with the vacuum getting stuck in the deep end on the returns and I have to manually get the vacuum off of them. The vacuum also doesn’t clean the stairs as it says it will so I am constantly manually cleaning them. I’m more upset that we payed a good deal of money for a vacuum that is supposed to work wirelessly and I can’t even get into the app on my phone. And the times I do get into the app I am signed out shortly after saying I don’t have connection, over and over again. My husband even put in additional routers and extenders thinking that was the problem at first and the app still doesn’t work as it should. Very disappointing for such a service that could be so useful.
