Karcher K7 Compact $643.3 + Delivery ($0 C&C/ In-Store) @ Supercheap Auto

Operating pressure 130 Bar
Max permissible pressure 180 Bar
Water flow rate 8.2L/min
Maximum flow rate 8.5L/min

Data looks quite good for a 19.4kg compact pressure washer.

If you use a nozzle with a slightly smaller diameter, you should be able to reach or exceed the maximum pressure.
