About Battery Powered Pressure Washers
The latest battery washers (Karcher KHB 6 Cordless, Bosch Fontus 18V-30, Makita DHW080) deliver 24–40 bar and run on existing tool platforms — so if you already own Makita LXT, DeWalt XR or Bosch 18V batteries, you save on the kit price.
Match the battery voltage to expected pressure: 18V single battery for inflation and rinsing, 36V/dual-18V for serious cleaning. A 5Ah pack typically delivers 25–35 minutes of trigger time.
Best for car detailers, cyclists, dog owners and anyone needing a portable washer at the allotment, beach or campsite.
