OK so.......the spot cleaners are essentially miniature canister cleaners for small areas. When I have to clean up occasional stains or cat puke...I have never used the solution tank...I just put a little carpet cleaner in a cup of hot water and pour over/ extract, rinse, rinse, extract. I don't think pushing more weight down is a false sense simply because the spot I cleaned and saturated HEAVILY dries much much faster than if I had used an upright (on my berber)
My rainbow Aquamate (I used it recently) I notice when the water tank is FULL it extracts more water because of the weight of the water. As the tank empties, the aquamate gets lighter and seems to extract LESS because of less weight. I have this odd shaped 10lb hand weight that I just placed on top of the aquamate and surprisingly it stayed there without fall off because of its shape...I think I'm extracting 30% more water with the weight than without it.
