STIHL RCA 20 Specifications

Battery runtime is approximate and varies depending on pressure setting, application, operating mode, battery condition, and other working conditions.

STIHL RCA 20 Cordless Pressure Washer

The STIHL RCA 20 cordless pressure washer is designed for smaller cleaning jobs where portability is more important than the output of a full-size pressure washer.

Typical applications can include:

• Cleaning vehicle wheels and tires
• Rinsing garden tools
• Cleaning patio furniture
• Washing outdoor equipment
• Light cleaning around the home
• Camping and recreational cleanup
• Watering plants using the shower setting

Portable Cleaning Without a Mains Water Connection

The RCA 20 can operate using multiple water sources.

Depending on the setup, it can be connected to:

• A pressurized garden hose
• The supplied siphon hose
• A nearby bucket or suitable water source
• The supplied one-gallon water bag

This makes the RCA 20 especially useful in areas where a standard hose connection is not readily available.

4-in-1 Nozzle

The included 4-in-1 nozzle lets the operator quickly change spray patterns without installing a separate nozzle for each task.

The available settings include:

• Flat spray for broader cleaning coverage
• Point / narrow jet for concentrated cleaning
• Rotary jet for more aggressive cleaning action
• Shower setting for gentle rinsing and watering

This flexibility allows the RCA 20 to move between cleaning and watering applications using one nozzle assembly.

Up to Approximately 350 PSI

The supplied product information lists maximum pressure of approximately 24 bar / 350 psi.

The RCA 20 is intended primarily for smaller-scale residential and portable cleaning work rather than replacing a full-size high-pressure washer for heavy-duty applications.

ECO Mode

The RCA 20 includes an ECO mode that reduces pressure for lighter or more delicate applications.

Using ECO mode can also help extend battery runtime when full output is unnecessary.

This gives the operator two useful approaches:

• Full power for tougher cleaning tasks
• Reduced-pressure ECO mode for lighter work and improved battery efficiency

Two STIHL AS 2 Batteries Included

This RCA 20 Set includes two STIHL AS 2 lithium-ion batteries.

The supplied technical information lists approximately 8 to 15 minutes of working time per AS 2 battery, depending on the application and operating mode.

Having two batteries in the set allows one battery to be available while the other is charging or waiting for use.

STIHL AS Battery System

The RCA 20 is part of the compact STIHL AS Battery System.

This set includes:

• 2 AS 2 batteries
• 1 AL 1 charger

The same compatible AS-System battery platform can be used with other applicable STIHL AS tools.

Siphon Hose for Remote Water Sources

The supplied siphon hose allows the RCA 20 to draw water from a suitable external source when a pressurized hose connection is not available.

The supplied product information identifies a hose length of approximately nine feet.

A filter strainer helps prevent larger debris from being drawn into the cleaner.

Detergent Sprayer Included

The RCA 20 Set also includes a detergent sprayer for compatible cleaning agents.

This can help loosen stubborn dirt before rinsing.

Always follow the cleaning-product manufacturer's instructions and STIHL operating guidance when using detergent or other cleaning products.

Lightweight Handheld Design

The RCA 20 weighs approximately 2.8 lb according to the supplied technical specifications.

Its ergonomic handle and compact form are designed for easy maneuverability during smaller cleaning jobs.

The lightweight design also makes the RCA 20 easier to transport compared with a conventional wheeled pressure washer.

IPX4 Weather-Resistant Construction

The RCA 20 is rated IPX4 for splash-water resistance.

This rating indicates that the unit has been designed and tested for protection against splashing water under the conditions specified by the applicable rating.

Storage Bag Included

The RCA 20 Set includes a storage bag designed to hold the cleaner and its supplied accessories.

The compact system allows the RCA 20, siphon hose, water bag, detergent sprayer, spray lance, and related accessories to be stored together for easier transportation.
