Zoom on the Stihl RE 90

In a nutshell, the Stihl RE 90 is a light duty pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:

  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • 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 Stihl RE 90 in use

The Stihl RE 90

The Stihl RE 90's axial pump, powered by a 13 amp universal motor, can provide a pressure of up to 1800 PSI (approximately 30 times more than a standard garden hose) and a flow of up to 1.2 GPM (values claimed by the manufacturer). The Stihl RE 90 thus has 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.

Standing at only 23.4 lbs, this model can be carried around very easily. This is, in part, thanks to its plastic frame, which allows it to remain as lightweight as possible. To further improve its transportability and ease of use, the unit also features a set of two solid wheels.

Main Features

The Stihl RE 90 in use

The Stihl RE 90

The Stihl RE 90 comes with a spray gun, a wand, a pressure hose, 2 nozzles and a detergent addition feature, which are detailed 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: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
  • 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.

Other Features

Some of the included accessories

  • Onboard storage: The Stihl RE 90 features a handy storage area, which allows you to neatly store nozzles and accessories and be always prepared by having everything needed at hand.
  • Pressure control: Water pressure can be manually changed, by rotating the fan-jet nozzle.
  • Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation).
  • Accessories: Included with the Stihl RE 90 are also the owner's manual (opens in a new tab) and some basic documentation to get you promptly started, along with several accessories, such as foam cannon (to add cleaning solutions to the water), wand, spray gun, pressure hose and power cord.
