I have this product and it's pretty awesome. There are a lot of little improvements compared to the standard diamond clean. I like that it automatically detects what type of brush head you put on and changes to that mode. I also enjoy having 6 total quadrants, 3 on top and 3 on bottom, instead of the standard four with a beep after 30 seconds. This results in less scrubbing and better coverage for me, especially when I'm following on the app. I don't think it's worth $329, but it will come down quickly in price.
