Devin - That powerhead does indeed look like a modernized version of the powerhead used on the Fakir Combivac 1117 upright that we had in Canada through vac shops in the late 2000's. The height adjustment pedal gives it away that Fakir makes this, and they modernized it with the plastic brushroll with "beater bars" and the removable bottom plate. All Fakir powerheads use geared belts, so I would imagine this one does as well.
This does look like a very nice canister! And it looks like it cleaned well in Tom's video. But - what's Delphin's excuse for having to plug in the hose's powerhead cord at the canister when most of the other water vacs - like Rainbow and Hyla - did that ages ago. The water basin looks like it has a small capacity and VERY awkward to remove and empty it. And I would also question the reliability of that separator design over time - I could see that being repair prone put into the hands of the wrong user that doesn't care for things. I don't see any HEPA exhaust filter, no cord rewinder, and no tool storage either.
For these reasons, I would have to pass on it if I had a DTD guy come knocking at my door. If I was going to invest in a water filtration vacuum, I would buy a Rainbow E2 with the GS Electric carbon brush motor, refurbish it with new carbon brushes, buy a spare motor and carbons to set aside, and get a new Wessel Werk EBK360 powerhead with a Rainbow powerhead cord put on it to optimize the carpet cleaning performance. I personally feel the Rainbow E2 was the best Rainbow has put out to date for suction and airflow without needing a switched reluctance motor with a board to fail. And amongst the water filtration vacuums, it cleans the best, and I don't need multiple speed settings and a circuit board to keep me happy.
