About 40V Pressure Washers
These higher-voltage cordless platforms hit 40–60 bar at 4–6 L/min — twice the pressure of single-18V models. Runtime is typically 25–40 minutes on a 5Ah pack.
Top picks: Greenworks 60V (60V badged but in the 40V power band), Karcher K3 Battery Set 36V, EGO Power+ HPW3000 (56V). Most include a battery and charger.
Best for off-grid washing, allotments, campsites and car detailing where mains is inconvenient.
