Tom,
A booster pump will be WAY too powerful for ThePoolCleaner on a dedicated line. If you meant hooking up your main pump to the dedicated line in addition to the regular returns, then you are right that it might not be powerful enough, but having a switch valve to have most flow go to the cleaner would work (but then circulation might not be as good from the other returns).
One other thing I forgot to mention is that ThePoolCleaner hose is thick -- I think it's 2" and it is noticeably larger in diameter than a regular pressure side cleaner hose. They have special fittings/adapters to convert the normal 1.5" screw for the return into their required fitting.
To get the 15 GPM and roughly 14+ RPM from ThePoolCleaner (which, again, is on the high side of what they say is needed), my pump was at 2180 RPM going only to the 1.5" dedicated line. Most of the pressure (7 PSI out of 11 PSI) was from the cleaner as 15 GPM through the pipe has relatively little loss. So the high end of the cleaner operating range is 7 PSI (for the cleaner alone, incremental to losses in the line) and 15 GPM while the cleaner is supposed to operate at lower flows/pressures as well though my experience with some flow directed to other returns and a wheel RPM closer to 11 instead of 14 was that it didn't clean as well.
