pressure washer?

Isn't that what an expresso machine already is? All be it pressure
from boiling water rather than a pump...


Most have a pump. Although I did have a Krups machine about twenty years
ago that just used the steam pressure to force water through the coffee.

Connoisseurs say the pumped kind is better, because the somewhat lower
water temperature (90°C, I think) produces better-tasting coffee, or
something like that. The steam pressure kind is cheaper to
manufacture.
