STIHL RCA 20 cordless pressure washer, with 2x AS 2 batteries and AL 1 charger

If you want fast, light cleaning anywhere without dragging out a hose or power lead, the STIHL RCA 20 set is the simple answer. This cordless pressure washer runs off the AS System and even works where there’s no tap or socket. Draw water from a rain barrel with the suction hose or fill the foldable tank and you’re ready to rinse off mud, dust and grime on the spot.

Despite its compact 1.3 kg build, it packs up to 24 bar and a versatile 4‑in‑1 nozzle, so you can switch spray patterns in seconds for furniture, bikes, barbecues and garden toys. The set includes two AS 2 batteries and the AL 1 charger, so you can keep moving.

Where it shines

• Quickly rinse bikes after a muddy ride, right at the car
• Freshen up garden furniture at the start of the season
• Clean grills, toys and small patios without setup fuss
• Take portable cleaning to the campsite or allotment

Why this set makes life easier

• Truly go-anywhere: use a tank or draw from a barrel
• 4-in-1 nozzle changes spray without swapping parts
• Lightweight body reduces arm fatigue
• Two batteries included to extend working time
