Description

This gas pressure washer is lightweight, easy to store, and provides a powerful pressure washing experience.

Zoom on the Simpson CM61455-S

The Simpson CM61455-S is a heavy duty pressure washer, and enables:

  • focused spot cleaning on hard, unpainted surfaces, accessing high spots, and efficiently eliminating stubborn stains
  • complete cleaning of hard surfaces, vehicle washing, and surface prep for painting
  • soft cleaning of delicate surfaces, and gentle cleaning for larger areas with low pressure
  • applying detergents and cleaning agents, and rinsing off surfaces

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

Power

Powered by a 170cc engine, its axial cam pump can deliver a pressure of 2900 PSI (around 48 times more than a standard garden hose) and a flow of up to 2.4 GPM (CETA-certified values). With these values combined, the Simpson CM61455-S boasts a cleaning power of 6960 Cleaning Units.

To initiate the engine of this gas-powered pressure washer, a traditional pull-start mechanism is employed.

The pressure washer's tank has a maximum capacity of 0.21 gallon for storing gasoline.

Design & Handling

With its hand truck design and approximate dimensions of D22 x W18 x H35.8 in, the Simpson CM61455-S provides great mobility. The robust steel frame guarantees longevity of the assembly, providing stability and protection for internal components, even under demanding working conditions. The handle adds to the CM61455-S convenience of transport.

With a weight of 50 lbs, the unit is comfortably maneuverable for most users, allowing for efficient handling during cleaning tasks. That weight is mainly due to the inclusion of the 170cc engine and a solid steel frame. Despite this, the CM61455-S's two 12" never-flat wheels ensure effortless maneuverability.

Main Features

The Simpson CM61455-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: Detergent is fed in through a siphon hose, since the device lacks a soap tank. The pressure washer automatically dispenses and mixes the detergent with the water when a soap nozzle is attached.
  • Pressure hose: For easy organization, the included 25 ft ⌀1/4" high-pressure hose can be stored on the unit using a set of convenient hooks when it's not in use, ensuring a clutter-free workspace.
  • Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
  • Nozzles: Below, you'll find a table outlining the 4 included nozzles and their recommended surfaces.
