Zoom on the Simpson PS61201

In a nutshell, the Simpson PS61201 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:

  • spot cleaning of hard, paint-free surfaces and out-of-reach areas
  • intense cleaning of hard, unpainted 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

Its axial cam pump, which utilizes a 196 cc (6.5 hp) engine, may deliver a pressure of up to 3500 PSI (almost 58 times more than a standard garden hose) and a flow of up to 2.5 GPM. These values correspond to a cleaning power of 8750 Cleaning Units.

This gas-powered pressure washer’s KOHLER SH270 engine is started by a traditional pull-start mechanism.

The fuel is stored in a tank, which can hold up to 0.88 gallon of gasoline.

Design & Handling

The wheelbarrow design of the Simpson PS61201 grants mobility and stability to the unit. The robust welded steel frame guarantees longevity of the assembly. The handle adds to the PS61201 convenience of transport.

The majority of users will be able to maneuver this unit easily, it only weighs 74 lbs. Its 196 cc KOHLER SH270 engine and welded steel frame account for a good chunk of that weight. However, the two 10" pneumatic wheels allow the PS61201 to be easily manipulated and maneuvered.

Main Features

The Simpson PS61201'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: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. The Simpson PS61201 features an automatic soap dilution mechanism, that will dilute your detergent with a 7:1 ratio. The detergent is automatically added to the water when a soap nozzle is connected.
  • Pressure hose: The included 25 ft ⌀5/16" high-pressure hose can be neatly stored on the unit when idle thanks to a set of convenient hooks.
  • Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
  • Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.
