About the STIHL RCA 20 Cordless Handheld Pressure Washer
The STIHL RCA 20 Cordless Pressure Washer is a compact, portable cleaning solution that delivers powerful performance without the need for a direct power or water connection. Powered by STIHL’s advanced 10.8V AS 2 battery, this handheld pressure washer is designed for small cleaning tasks at home, in the garden, or on the go.
It’s perfect for cleaning outdoor furniture, patios, barbecues, play equipment, bikes, and more. Thanks to its cordless design, it’s also ideal for camping trips, bike trails, and any location where water and power access might be limited.
(Please note this product can be bought as the shell only, where it does not come with a battery or charger, or as a ‘kit’ where its comes with two batteries and a battery charger.)
Effortless Cleaning with Portable Power
The RCA 20 Cordless Pressure Washer offers maximum convenience with its lightweight design, weighing just 1.5 kg. This makes it easy to handle and reduces fatigue, even during extended cleaning sessions. Despite its compact size, it delivers an impressive maximum pressure of 24 bar, ensuring effective dirt removal.
The washer comes with a 5-metre suction hose and a 20-litre water container bag, allowing it to draw water from any available source. Simply connect the suction hose to the washer and submerge the filter end into the water container. This level of flexibility means you’re no longer tied to a fixed water supply. You can take the RCA 20 wherever it’s needed most, whether that’s your garden, garage, or a remote outdoor location.
Versatile Cleaning Modes with a 4-in-1 Nozzle
The 4-in-1 multi-nozzle makes switching between cleaning tasks seamless. You can easily toggle between rotary, fan-jet, narrow jet, and watering modes, ensuring you always have the right spray pattern for the job.
The rotary nozzle is perfect for stubborn dirt, while the fan-jet provides broader coverage for large surfaces like patios and decking. The narrow jet delivers focused cleaning power for tough spots, and the watering mode is ideal for delicate surfaces or garden use.
The included spray lance extension adds even more flexibility, allowing you to adjust the washer’s range according to the task at hand. This makes cleaning comfortable and efficient, even when dealing with hard-to-reach areas.
Consistent Performance and Eco Mode Efficiency
Unlike many other cordless pressure washers, the RCA 20 maintains consistent power throughout the entire battery charge. Thanks to STIHL’s intelligent electronics, you won’t experience power loss as the battery depletes. This ensures every job is completed with maximum efficiency.
When you don’t need the washer’s full power, simply activate Eco mode at the touch of a button. This reduces power consumption, extending battery runtime without compromising on performance for lighter tasks. On a fully charged AS 2 battery, the RCA 20 offers up to 15 minutes of continuous cleaning, enough for most household and outdoor cleaning needs.
Complete with Practical Accessories
The STIHL RCA 20 doesn’t just come as a standalone tool. Included as standard are a range of practical accessories designed to enhance usability and ensure you’re ready for any cleaning task.
A detergent spray set is included for tackling stubborn dirt and grime, allowing you to apply cleaning agents directly through the nozzle. The water container bag holds up to 20 litres of water and seals watertight for easy transport, making off-grid cleaning straightforward and mess-free.
All accessories, including the suction hose, spray lance, and detergent set, conveniently fit into the included carry bag, ensuring the entire kit is easy to store and transport.

With its portable design, robust power, and flexible water sourcing, the STIHL RCA 20 Cordless Pressure Washer is an ideal companion for active lifestyles. It’s particularly suited for those who enjoy outdoor adventures, from camping to cycling, providing a quick and effective way to clean equipment and vehicles.
