I just used my new Dolphin Liberty 400 (cordless) for the first time and its run a full cycle with wall climbing etc but when it finished, there are large areas completely untouched. It seems to have only covered around 60% of the pool floor. I watched it spend a lot of time down one section of the pool. This thing does not clean my pool anywhere near as well as my suction cleaner. I thought these things had some sophisticated navigation system to completely clean the whole pool? I'll be taking it back to the shop I purchased it from if this is the best it can do.
I have the S400, Same issue. It does pick up but it doesn't leave the pool clean
Spot on. This thing is junk. I’m lucky to get 10% of my pool clean because it goes back and forth from my step to the back wall. That’s it! Sent it back to Maytronics and they said it works fine. Now they refuse to speak or call me back.
I took mine back to the store I purchased it from and they took it back and I swapped it for the Dolphin M6oo corded model. This one is brilliant. Absolutely chalk and cheese comparison. It cleans the pool perfectly and because it's corded, it can go again and again if needed. The S400 sounds like a good idea in concept but the reality is quite different.
