Right now both my Blue Diamonds are in the shop...luckily the old was still under warranty. They say they'll be fixed by next week, latest.

The first one ran four years then a motor popped a seal and it started leaking oil. The second ran for 2 months and died.

But I had a Dolphin Dynamic before and it ran GREAT for 2 years, then wouldn't run. I sent it back to them 3 times because each time they said it was fixed and it wasn't (and took over a month each time). The last time they sent me a new unit! That worked OK but had trouble climbing the walls (Motors are too small). I sold it because the first Blue Diamond was so much faster and more effective.

We'll see how they do on the repairs.....Check back with me in 2 weeks.
