This washer is powered by the reliable & highly respected Honda GCV135 engine. The DeVilbiss washer puts out a powerful 2200 psi stream. The adjustable wand provides a range of stream from a pencil beam to a broad brush 40-degree swath and is great for driveways, sidewalks, decks & docks, rock walls, etc. No nozzles to fly off into the brush, never to be seen again. Complete with manuals for both the engine & washer.
