I really like their drive system. No gears, chain or seals to worry about, and the wearing components are simple to fabricate and replace. The mesh is also completely user replaceable - even with 3rd party components.
I made an enquiry with Veolia hydrotech, and their replacement panels are literally an arm and a leg and probably a kidney to go.
The motor mounting enclosure is shock mounted and the motor itself is a standard form factor oversized unit that will comfortably handle the job of turning the drum.
Using a stauff clamp to hold down the spray bar is a nice touch. Everything can be easily replaced if the need arises.
It's really a far cry from the Blue Eco...
The Blue Eco still has its charms though. I might pull it from my current pond before the house is sold, and set it up for an aquaculture experiment in the back yard.
