Wanted to give everyone a heads up on my experience with Dolphin/Maytronics...the unit was used exactly one season...when put in the pool this year, the motor died...sent it back for warranty service the end of June...it is now August 13th and we still do not have the unit back. Folks at Dolphin are extremely unapologetic...apparently the motor is on back order. How does a pool cleaning robot company have a back order on motors. This has cost me hundreds of dollars in weekly pool service.
Needless to say I would never recommend this unit or the Dolphin/Maytronics companies.
