Description

Zoom on the DeWalt DXPW3123

In summary, the DeWalt DXPW3123 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:

  • spot cleaning of hard, unpainted surfaces or high reach areas
  • cleaning of painted or delicate surfaces
  • use of detergent and cleaning solutions

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

Powered by the brand new Honda GCV170 (opens in a new tab) engine, which is specially built for pressure washers, its axial cam pump can deliver a pressure of 3100 PSI (around 52 times more than a standard garden hose) and a flow of up to 2.3 GPM (CETA-certified values). Combined, these values mean that the DeWalt DXPW3123 has a cleaning power of 7130 Cleaning Units.

The 166 cc engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

A fuel tank with a maximum capacity of 0.24 gallon is used to store gasoline.

Design & Handling

The DeWalt DXPW3123 offers superb mobility, with a hand truck design and approximate dimensions of D23.8 x W18 x H35.8 in. The robust steel frame guarantees longevity of the assembly. The handle adds to the DXPW3123 convenience of transport.

The majority of users will be able to maneuver this unit easily, it only weighs 56 lbs. A major component of its weight are its 166 cc Honda GCV170 engine and steel frame. Since the DXPW3123 has a set of two 12" never-flat wheels, it is still easily maneuvered and manipulated.
