No it wasn't the Hyla but may have been called the Robot. I know one water-type machine under this name was sold in Euroe for a time. It was almost a dead ringer for the Rainbow SE. If my recall is correct, a similar machine was put into production in Mexico and a lawsuit came out of that. I did a search and there is a U.S. Court of Appeals PDF document that I can't get to download that appears to mention the matter.
What I can't recall is whether Ocean Blue is the same blue-colored machine that was being advertised on TV here and there. That machine did not have the Wessel-Werk power nozzle.

To be brief, the lookalike Rainbow was ROBOT. I remember seeing the machine and noticing how much it looked like a Rainbow.
Rexair wanted the company to make the Rainbow for them. Later, this company backed out and made their own Rainbow lookalike. Rexair did not like that, so they took them to court and vise versa. There have been other companies who have ventured on their own, to make their own version of a well known vacuum cleaner brand.
This Ocean Blue is owned by a company I would not get involved with, IMHO. They sell more than vacuum cleaners and air cleaners.
I have seen the Ocean Blue before under a different name. It used the same color scheme, but had a cheap hose, plastic wands, and a cheaper power nozzle. With the OB, I noticed that they added a metal panel around the machine(the previous brand had grey plastic where the metal panel is), added a better hose and deluxe W-W nozzle. The price is higher also.
