(Upgraded 2026) Nautilus Titan Wi-Fi Automatic Robotic Pool Vacuum Cleaner Waterline Scrubbing, Multi-Layer Filtration, Ideal for Inground Pool up to 50 FT in Length

Last summer was the first year I had the pool robot it worked great. This summer 2024 our second summer with the robot and still works great. It works so well I am questioning the need for the pool company I hire every summer. My pool is 20’x40’ and it does a great job cleaning it. The picture are for today July 2nd, we had fireworks at the house which left a massive mess in the pool. I turned on the Dolphin to start cleaning after the fireworks, then the normal 5 am clean this morning. I was so surprised as to how clean it was when I woke up. Still some debris in the pool but I think that is all due to the wind blowing it in to the pool from the grass during the day. I am also on the second season with my Betta (surface skimmer) these two in conjunction keep my pool super clean. I must say I find the Dolphin filter to be way better than my sand filter! I am a big fan of pool robots!!!

Bot does a great job of cleaning the pool. Very happy with function/performance. It did have an error and stop working after 6 months. The 3yr warranty is great, and Maytronics is happy to repair it. But - you will need to pay for shipping to them, so factor that cost into your calculations. After forum searches when trying to troubleshoot - I determined that these often have issues like mine. I originally thought it might be corrosion of the twist cable (as that is common.) However, mine only had minor non-impacting corrosion. In any case, be sure to save the box for when you need to get it fixed!

Got the Dolphin E20 after my previous pool cleaner stopped working and based on a recommendation from my neighbour. I had been expensing loads of energy and wasted time dragging the hose around for a couple months to vacuum my pool. This unit was truly the best investment I made since deciding to put in my pool. Cleans the pool thoroughly, including the side walls up to the water’s edge within 3hrs which allows me time to do other things. Easy to clean and stow. My only disappointment is the Bluetooth capabilities and mobile app have limited features, are not the greatest and don’t work very well. You have to be 3 feet max away from the unit with your phone for the app to connect to the Robot and when it does some of the features don’t work.

So far so good. Had no issues setting it up and getting it connected via the app. It is running on a schedule which works great. It has been doing a great job of getting all over the pool and I have not noticed it miss any areas yet. A big plus for me was that has not been getting stuck on my two main drains like my previous cleaner constantly did. This cleaner appears to go right over them with ease. Easy to retrieve and clean out the filters. It does appear to get all the way up to the waterline, which was not important for me, but a nice addition.

This unit is to replace my nearly 10 year old Dolphin M400. As far as I could tell, the specs from this unit to the M400 are identical. 3 motors - 2 drive and 1 impellar (same as the M400). 4500 gallons per hour of water movement (same as the M400). Cleans sides and water lines and lets you use ultra fine filters as well - (did not come with these specifically - but had them from using my M400 and they are the exact same fit) It came with just the 1 basic set of filters. I have ran it probably 5 times now - just got it 5 days ago, and so far this unit - like the M400 has no problem with pool drains. I don't use the app - so I can't say anything about that, sorry.
