The invention relates to a high pressure washing apparatus for flat
surfaces (Specification 1:11-12). Claim 1 is illustrative:

chassis, the pump having an inlet and a high pressure outlet;
a rotary valve mounted to the chassis and fluidly
connected to the high pressure outlet and having at least two wands
connected to the rotary valve so that rotation of the valve causes the
wands to rotate; and

pressure water is sprayed from the nozzles toward the surface.
The Examiner relies on the following prior art reference to show
unpatentability:
