They are, almost everybody's robot around here is a Maytronics. They are pretty much the pool robot leader.
Just ask your pool builder if he is planing on a pressure robot, if so turn it down and get a real robot. If you cannot get into the beta (I think it will be hard). Then plan on designing a good storage spot for a Maytronics robot and make sure you get a good GFI outlet installed close by to power.
Get think it through and do a nice design. It was one of the mistakes I made when I re did my pool.
