Zoom on the Simpson MS60773-S

In a nutshell, the Simpson MS60773-S is a medium to heavy duty pressure washer that allows:

  • spot cleaning of hard, paint-free surfaces and out-of-reach areas
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and frail surfaces
  • use of detergent and cleaning solutions

Ahead are presented its power characteristics and design, its main features and any other additional features.

Power

The Simpson MS60773-S in use

The Simpson MS60773-S

Its axial cam pump, which utilizes a 160 cc (4.4 hp) engine, may deliver a pressure of up to 2800 PSI (almost 47 times more than a standard garden hose) and a flow of up to 2.3 GPM. These values correspond to a cleaning power of 6440 Cleaning Units.

The Honda GCV160 engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

The fuel is stored in a tank, which can hold up to 0.25 gallon of gasoline.

Design & Handling

With its hand truck design and approximate dimensions of D26 x W18 x H35 in, the Simpson MS60773-S provides great mobility. The robust steel frame guarantees longevity of the assembly. The handle adds to the MS60773-S convenience of transport.

The majority of users will be able to maneuver this unit easily, it only weighs 61 lbs. Its 160 cc Honda GCV160 engine and steel frame all add up to a substantial part of that weight. Since the MS60773-S has a set of two 12" never-flat wheels, it is still easily maneuvered and manipulated.

Main Features

The Simpson MS60773-S in use

The Simpson MS60773-S

The Simpson MS60773-S's package includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, with a more detailed description below.

  • Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The detergent is diluted with a 7:1 ratio by the Simpson MS60773-S's automatic soap dilution mechanism. The detergent is automatically added to the water when a soap nozzle is connected.
  • Pressure hose: The included 25 ft ⌀1/4" high-pressure hose can be neatly stored on the unit when idle thanks to a set of convenient hooks.
  • Spray gun and wand: Both the classic ergonomic spray gun and its steel wand may be conveniently stored in a side hook.
  • Nozzles: The table below shows you the 4 included nozzles, as well as the surfaces they're the most appropriate for.

  • Safety: Safety of operation is enhanced by a thermal relief valve (which helps to prevent internal pump damage) and a trigger lock mechanism (which prevents accidental operation).

  • The Simpson MS60773-S with its 2800 PSI achieves a lower pressure value, compared to other gas-powered pressure washers in the $300-400 price range. As for the device with the most powerful water stream, in this price range, one of the top products is the Simpson CM61083 with 3400 PSI.
  • The achievable water flow of this washer, which reaches 2.3 GPM (gallons per minute) can be described as low, compared to other devices in its price range. If maximum rinsing efficiency is your top priority, one of the devices with the highest water flow in the same price range is the Predator 3100, with a GPM of 2.8.
  • With 6440 Cleaning Units (PSI X GPM), the MS60773-S is on the low end when compared to other similarly priced gas-powered devices. If you consider the highest overall cleaning power as a really important factor, the Predator 3100 and its 8680 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.
