Where does the extra pressure come from? Is there a pump involved?
The Altered: Shower takes a different approach, with the Dome nozzle expelling water in a rotating dome shape. This tears the water into thousands of large droplets that spread out in a random pattern to provide full coverage….
…the Dome technology actually increases the speed of the water to provide the pressure sensation of a conventional shower…

OK. Makes sense.
No, it doesn’t make sense. It’s just like the old whirligig roof ventilators – which are no more effective than a simple hole in the roof.
In this case the water pressure drives the rotation. The water pressure is doing work so the outlet pressure is less than the inlet pressure. The rotation robs the water of pressure. It’s the same pressure reducing mechanism as in other swirling pressure reducers.
My present shower nozzle is a water saving nozzle, a good one. It doesn’t have lots of large holes – which the non-water saving nozzles do. It doesn’t have a swirling pressure reducer in the throat – which the awful (free supplied by council) water-saving nozzles do. It doesn’t have a few small holes supplying needle shower pressure with hardly any water – which the first water saving nozzles did. There’s no spin so you’re not losing pressure.
Instead it has a ring of mid-size holes. Relatively few holes of relatively small size give it its water-saving capability. The single ring with nothing inside gives good coverage. And by being not tiny holes you aren’t short of water. The brand name is Interbath.
