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, paintless surfaces and reaching far-away areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted or delicate surfaces
  • use of detergent and cleaning solutions

The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

Power

The Simpson PS60843 in use

The Simpson PS60843

With an impressive 420 cc engine, its triplex pump delivers a pressure of 4400 PSI (roughly 73 times more than a standard garden hose) and a flow of up to 4 GPM (CETA-certified values), resulting in the Simpson PS60843's 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.

This model weighs 138 lbs. For this reason, it cannot be called lightweight and thus, carrying and transporting it might be somewhat challenging. Its 420 cc Simpson engine, the triplex pump and welded steel frame are mainly responsible for its heavy weight. However, the unit is mobile thanks to its two 13" pneumatic wheels, which add to its movability and allow it to be manipulated smoothly on the job.

Main Features

The Simpson PS60843 in use

The Simpson PS60843

The Simpson PS60843 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed 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. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
  • 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: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
  • Nozzles: The 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.

    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
