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

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

The Simpson PS60843 in use

The Simpson PS60843

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.

Main Features

The Simpson PS60843 in use

The Simpson PS60843

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.

    I bought this model and I gotta say it is a work horse,it is well worth the money,its ungodly the cleaning power for the price. It’s not a hot water pressure washer but the power makes up for it. I know there’s differences ,but it’s a dependable piece of equipment I give it on scale 1 to 10 a easy 9.5 the only reason not a 10 is because you dont want to make the mistake to not have the wand gripped when starting the pull start cord. I read where alot of buyers bought it and didnt pull the wand trigger when starting the motor.it will dislocate a shoulder almost but with the wand trigger pulled I can easily start the machine with one hand and o e hand holding the wand compressed. I give it a 10. My buddy do to not pulling the trigger gave it a 3 until he seen what it can do now he gives it a 9 so that equals 9.5. Also great at Lower pressure cleaning to.

    + PROS: It's a work horse well worth the money strong well made dependable, dont be stupid Honda is way more expensive,but has nothing on this Simpson, I use it everyday no problems can NBC t say the same for honda
    - CONS: Make sure to compress the wand handle when starting,keep from hurting yourself,but if you compress trigger on wand it's easy enough
