The STIHL RCA 20 is a game-changing addition to the AS System, designed for those who need instant cleaning power without being tethered to a garden hose or a power socket. While traditional pressure washers are bulky and restrictive, the RCA 20 is a handheld, lightweight powerhouse weighing only 1.3 kg ($2.9\text{ lbs}$), making it the most portable cleaning solution in the STIHL lineup. It delivers a surprising 24 bar (350 psi) of maximum pressure, fueled by the same AS 2 battery that powers your GTA 26 pruner and HSA 26 shears. Whether you are washing down a muddy mountain bike at the trailhead, cleaning garden furniture in a remote corner of the lawn, or rinsing salt off a jet ski, the RCA 20’s ability to self-prime from a bucket, lake, or the included 20-litre water bag means you are never restricted by infrastructure. It’s the “grab-and-go” hero for adventurers and meticulous homeowners alike. Self-Siphoning “Any-Source” Suction: Unlike standard handheld washers that require a pressurized tap, the RCA 20 comes with a 5-metre suction hose and integrated filter. This allows the unit to draw water directly from rain barrels, buckets, or even natural water sources, making it truly off-grid. Integrated 4-in-1 Multi-Nozzle: Eliminate the hassle of swapping tips. The RCA 20 features a rotating head that instantly switches between a Fan Jet (for surface cleaning), a Rotary Nozzle (for stubborn grime), a Narrow Jet (for focused power), and a Watering Mode (for delicate plants). One-Touch “ECO Mode” Efficiency: To maximize your cleaning time, the RCA 20 features a dedicated ECO button on the chassis. This reduces pressure for lighter tasks like rinsing down a car or watering flowers, extending your battery life significantly. Bi-Directional OLED Battery Management: The built-in screen doesn’t just show a vague bar; it provides a real-time digital readout of your remaining battery percentage and your current operating mode (Standard vs. ECO), so you never run out of juice mid-rinse. The “Carry-All” Mobility Kit: Every RCA 20 includes a high-durability storage bag that neatly fits the washer, the 5m suction hose, the detergent spray set, and even the 20L collapsible water container, turning the entire setup into a single shoulder-carry unit. Constant Power Electronics: STIHL’s intelligent circuitry ensures the water pressure remains at a steady 24 bar until the battery is completely exhausted, preventing the frustrating “power fade” common in cheaper cordless alternatives. Detergent Injection System: Included as standard, the clip-on detergent set allows you to apply snow foam or car shampoo directly through the lance, providing a professional finish that manual scrubbing simply can’t match.
