Description

When it comes to tackling the toughest outdoor cleaning projects around the home, the Powermate 3100 PSI pressure washer fits the bill. A 30-ft. non-marring, high-pressure PVC hose lets you cover a lot of area, while five quick-change nozzle tips — a 0°, 15°, 25°, 40° and low-pressure soap tip — give you plenty of cleaning options.

Zoom on the Powermate 7131

In summary, the Powermate 7131 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:

  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted or delicate surfaces
  • applying 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

With a powerful 208 cc (5.8 hp) engine, its aluminum axial cam pump delivers a pressure of 3100 PSI (roughly 52 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer), resulting in the Powermate 7131's cleaning power of 7750 Cleaning Units.

A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Generac engine.

The fuel is stored in a tank, which can hold up to 0.87 gallon of gasoline.

Design & Handling

The Powermate 7131 is very mobile, due to its hand truck design and approximate dimensions of D23.6 x W19.7 x H40.3 in. The strong welded steel frame assures assembly longevity. The foam-padded fixed handle adds to the 7131 convenience of transport, while offering a comfortable grip.

The majority of users will be able to maneuver this unit easily, it only weighs 57 lbs. A major component of its weight are its 208 cc Generac engine and welded steel frame. Since the 7131 has a set of two 10" never-flat wheels, it is still easily maneuvered and manipulated.

Main Features

The Powermate 7131 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: Detergent storage is ensured by a 0.3 gal tank. It must be noted that the Powermate 7131 doesn’t come with a soap dilution mechanism. Therefore, you must always make sure that your detergent is correctly diluted. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
  • Pressure hose: The 30 ft ⌀0.3" high-pressure hose (3100 PSI rating), which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
  • Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
  • Nozzles: The following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.
