Zoom on the Stihl RE 90

The Stihl RE 90 is a light duty pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • spot cleaning of hard, unpainted surfaces or high reach areas
  • application of detergent and cleaning solutions

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

Power

The Stihl RE 90 in use

The Stihl RE 90

Its axial pump, which utilizes a 13 amp universal motor, may deliver a pressure of up to 1800 PSI (almost 30 times more than a standard garden hose) and a flow of up to 1.2 GPM. These values correspond to a cleaning power of 2160 Cleaning Units.

As it is an electric pressure washer, the motor of the RE 90 gets easily started by a simple ON/OFF switch. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.

Design & Handling

With its portable design and approximate dimensions of D13.3 x W11.4 x H33.9 in, the Stihl RE 90 makes mobility one of its core strengths. The handle adds to the RE 90 convenience of transport.

Because the device weighs just 23.4 lbs, carrying it around is very easy. This is, in part, thanks to its plastic frame, which allows it to remain as lightweight as possible. A set of two solid wheels also improves the ease of transport of the device.

Main Features

The Stihl RE 90 in use

The Stihl RE 90

The Stihl RE 90's package includes a spray gun, a wand, a pressure hose, 2 nozzles and a detergent addition feature, with a more detailed description below.

  • Soap addition: Detergent is added to the water at the exit, by attaching the included foam cannon to the end of the wand. However, since the Stihl RE 90 does not feature a soap dilution mechanism, you'll have to make sure your detergent is correctly diluted before use.
  • Pressure hose: A neat storage for the included 19 ft high-pressure hose is facilitated by a set of convenient hooks.
  • Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
  • Nozzle: 2 nozzles are included. The rotary-jet nozzle can be used to remove stubborn dirt, while the fan-jet nozzle is suitable for cleaning larger surfaces.
