Zoom on the NorthStar 15782020

In a nutshell, the NorthStar 15782020 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, paintless surfaces and reaching far-away areas
  • intense cleaning of tough, paintless 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 NorthStar 15782020 in use

The NorthStar 15782020

Using a powerful 389cc (11.7 hp) engine, its triplex pump delivers a pressure of up to 4000 PSI (roughly 67 times more than a standard garden hose) and a flow of up to 3.5 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 14000 Cleaning Units.

The Honda GX390 engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

Gasoline is stored in a steel fuel tank with a maximum capacity of 1.6 gallon.

Design & Handling

The NorthStar 15782020 offers superb mobility, with a hand truck design and approximate dimensions of L34 x W21 x H38 in. Its sturdy steel frame provides longevity to the assembly. The adds to the 15782020 convenience of transport.

The unit's weight of 185 lbs renders its carrying and transportation challenging, as it is far from lightweight. The major reasons for its heavy weight are its 389cc Honda GX390 engine, the triplex pump and steel frame. However, the unit’s two 15" pneumatic wheels are crucial to its maneuverability, since they provide a smooth method of manipulation on the job.
