Overview
A direct-drive CRX gas engine turns an axial cam pump with thermal relief, which pushes water through a steel wand and quick-connect nozzles. The frame is powder-coated steel with pneumatic tires.
High pressure and flow in a frame that rolls and stores easily are the reason to look, and it comes fully assembled. The listing counts five nozzles in the title and four in the description, so the exact set is unclear.
Who it's for
A homeowner who wants gas power for weekend cleaning of decks, patios and furniture. A buyer in a small flat who prefers plug-in convenience should look at an electric model.
Pros and cons
- High pressure and flow
- Gas engine needs fuel and upkeep
- Nozzle count stated two ways
- Heavy to lift into a vehicle
Performance notes
That pump, driven straight from the engine, converts engine speed into steady pressure, and thermal relief protects it when the trigger is released. Pressure strikes the surface with force while flow rinses debris away, and the narrowest tip concentrates the stream most. Soap is drawn through its own nozzle at low pressure.
