Dolphin M600

I purchased my M600 about 4 weeks ago, after wasting $725.00 on a crawler that ran through my pool filtration. The local sales guy bought a unit out for a demonstration, no pressure - he just let the unit prove itself. I purchased my M600 and he delivered it to my door the same day. His advice was to run the M600 with the installed filter setup, i.e. 2 x ultra fine filters for the first week 'until your pool is reasonably clean, then use 4 ultra fine filters'. I thought my pool was in OK shape. Could not believe what the M600 cleaned out of my pool in the first week and was then stunned what the ultra fine filters subsequently picked up - literally a jug full of grit and sand after the first 2 hour clean. My pool NOW looks amazing. The App is easy to setup and does everything Maytronics tells you it's supposed to do. The unit is easy to handle, use and store. Could not be more pleased.
