Zoom on the Simpson PS60843
The Simpson PS60843 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- spot cleaning of hard, paint-free surfaces and out-of-reach areas
- thorough cleaning of hard, paint-free surfaces
- cleaning of painted and fragile surfaces
- use of detergent and cleaning solutions
The Simpson PS60843's triplex pump, powered by a powerful 420 cc engine, can provide a pressure of up to 4400 PSI (approximately 73 times more than a standard garden hose) and a flow of up to 4 GPM (CETA-certified values). The Simpson PS60843 thus has a cleaning power of 17600 Cleaning Units.
This gas-powered pressure washer’s Simpson engine is started by a traditional pull-start mechanism.
Gasoline storage is facilitated by a steel fuel tank with a maximum capacity of 1.7 gallon.
Design & Handling
The wheelbarrow design of the Simpson PS60843 grants mobility and stability to the unit. Its sturdy welded steel frame provides longevity to the assembly. The handle adds to the PS60843 convenience of transport.
The device weighs 138 lbs and thus, is far from lightweight. Transporting and manually lifting it may therefore pose a challenge. Its 420 cc Simpson engine, the triplex pump and welded steel frame add up to a large chunk of the device's weight. However, the device’s two 13" pneumatic wheels play a key role in its maneuvrability, as they allow it to be manipulated smoothly.
Along with the Simpson PS60843 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The Simpson PS60843 has an automatic soap dilution mechanism, which dilutes the detergent using a 7:1 ratio. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
- Pressure hose: A neat storage for the included 50 ft ⌀3/5" high-pressure hose is facilitated by a set of convenient hooks.
- Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
- Nozzles: The following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.

- Onboard storage: Stay prepared for any job with Simpson PS60843's handy storage area, which allows you to neatly store any nozzles and accessories which you may need for the job.
- Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation), a low oil protection and a thermal relief valve (which helps to prevent internal pump damage).
- Accessories: Besides the usual owner's manual (opens in a new tab) and documentation to get you promptly started, the Simpson PS60843 comes with pressure hose, spray gun, wand and nozzle cleaner.
- Emissions: The Simpson PS60843 is NOT CARB-compliant and so you cannot buy it nor sell it in California.
