Zoom on the Simpson PS60843
The Simpson PS60843, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- spot cleaning of hard, unpainted surfaces or high reach areas
- intense cleaning of hard, unpainted surfaces
- cleaning of painted and frail surfaces
- use of detergent and cleaning solutions
Powered by an impressive 420 cc engine, its triplex pump can deliver a pressure of 4400 PSI (around 73 times more than a standard garden hose) and a flow of up to 4 GPM (CETA-certified values). Combined, these values mean that the Simpson PS60843 has a cleaning power of 17600 Cleaning Units.
The Simpson engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.
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. The strong welded steel frame assures assembly longevity. The handle adds to the PS60843 convenience of transport.
With a weight of 138 lbs, the model is not lightweight. Therefore, it may be challenging to manually carry it around and transport it. The major reasons for its heavy weight are its 420 cc Simpson engine, the triplex pump and welded steel frame. However, its two 13" pneumatic wheels play an important part in its maneuvrability, as they allow for a smooth manipulation on the job.
The Simpson PS60843's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description 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: Using a set of convenient hooks, the included 50 ft ⌀3/5" high-pressure hose can be easily stored on the unit when it is not running.
- Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
- Nozzles: The 5 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

- 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 spray gun, nozzle cleaner, wand and pressure hose.
- Emissions: The Simpson PS60843 is NOT CARB-compliant and so you cannot buy it nor sell it in California.
