Our take on the Karcher K 4 Power Control 1900 PSI Electric Pressure Washer

The Karcher K 4 Power Control is a corded electric pressure washer rated at 1900 PSI and 1.5 GPM, aimed at routine home cleaning like cars, patios, siding and garden furniture. Its standout feature is the Power Control spray gun, which pairs with the Vario Power Jet to set pressure by twisting the lance, plus a Dirt Blaster for tougher spots and a Plug 'n' Clean detergent tank. It weighs about 36 lb with packaging and runs on a standard 120 V, 13 A outlet with an 8 m hose and 5 m cord. At $226 at FactoryPure as of November 4, 2026, it sits at the low end of its recent range across the 8 stores listing it new.

Pros
  • Power Control gun and Vario Power Jet let you dial pressure by twisting the lance
  • 1900 PSI and 1.5 GPM handle cars, patios and light siding
  • Plug 'n' Clean detergent tank is quick to fill and swap
  • 8 m hose and 5 m cord give decent reach without moving the unit
  • Dirt Blaster included for stubborn grime
Cons
  • 36 lb with packaging makes it awkward to carry up stairs
  • Axial N-Cor pump is built for occasional use, not daily commercial work
  • 13 A draw needs a dedicated circuit; long extension cords are a bad idea
  • No onboard hose reel, so coiling is manual
  • Inlet water must stay at or below 40 °C

Questions and answers

Is the Karcher K 4 Power Control worth it?
For routine home cleaning like cars, patios and furniture, yes. At $226 at FactoryPure as of November 4, 2026, it is priced at the low end of its recent range. Skip it if you need a machine for daily or commercial use.
How is it different from the K 5 or K 3?
The K 4 sits between them: more pressure than the K 3 but less than the K 5, and it adds the Power Control gun. If you clean large areas often, the K 5's higher flow and pressure are worth considering.
What comes in the box?
The washer, a Power Control spray gun, a Vario Power Jet lance, a Dirt Blaster, a high-pressure hose and a detergent tank. No surface cleaner or extension wand is included.
Can I use it with a garden hose and standard outlet?
Yes. It draws from a normal garden hose and plugs into a standard 120 V outlet, pulling up to 13 A. Use a short, heavy-gauge extension cord or plug in directly.
When is it cheapest?
Pressure washers tend to drop in late fall and winter and around spring promotions. Track the price history and buy when it dips below the typical mid-range price.
