Curious to see if there are any solid robots that have been working well for more than 5-10 years? Just spoke to an individual that says that his old dolphin diagnostics robot was much better than a polaris that he bought recently..
I bought two used Dolphin Diagnostics about 8 or 9 years ago.. I used them in rent house pools and they were just retired the beginning of this year.. I did have to replace the tracks and bearings, but all and all, they worked well for over 10 years. I also had a Dolphin Premier at my home pool that I used for about 5 years before moving it to a rent house and it still works just fine.
The old Diagnostics have been replaced with the newer S200, which is a much better machine. No problems so far, but they have only been running about 8 months..
Interesting, I read on an article yesterday that the new tigersharks dont really introduce any new features, only cosmetics vs the 1st gen. Makes you think why such big company didnt make a change? maybe what they have works well? I do like the availability of the parts for the tigersharks too.
