Zoom on the Ryobi RY803423H

In summary, the Ryobi RY803423H 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
  • cleaning of painted or delicate surfaces
  • application 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 Ryobi RY803423H in use

The Ryobi RY803423H

Its axial cam pump, which utilizes a 187 cc engine, may deliver a pressure of up to 3400 PSI (almost 57 times more than a standard garden hose) and a flow of up to 2.3 GPM. These values correspond to a cleaning power of 7820 Cleaning Units.

This gas-powered pressure washer’s Honda GC190 engine is started by a traditional pull-start mechanism.

A steel fuel tank with a maximum capacity of 0.47 gallon is used to store gasoline.

Design & Handling

The wheelbarrow design of the Ryobi RY803423H grants mobility and stability to the unit. The robust steel frame guarantees longevity of the assembly. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

Weighing 70 lbs, the unit is easy to maneuver by most people. Its 187 cc Honda GC190 engine and steel frame all add up to a substantial part of that weight. Since the RY803423H has a set of two 10" wheels, it is still easily maneuvered and manipulated.

Main Features

The Ryobi RY803423H in use

The Ryobi RY803423H

The Ryobi RY803423H's package includes a spray gun, a wand, a pressure hose, a 5-in-1 nozzle 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 Ryobi RY803423H includes an automatic soap dilution mechanism, which will dilute the detergent using a 20:1 ratio. Detergent is automatically added to the water when "soap" is selected on the 5-in-1 nozzle.
  • Pressure hose: Using a set of easy-to-use straps, the included 50 ft ⌀1/4" high-pressure hose can be easily stored on the unit when it is not running.
  • Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
  • Nozzle: a 5-in-1 nozzle is included.

    Ryobi's 5-in-1 nozzle Ryobi's 5-in-1 nozzle offers five spray pattern settings (0°, 25°, 40°, short-range soap, long-range soap). Selection of a specific spray pattern is made by simply rotating the spray selector to the desired setting.

Other Features
