Karcher K4 Power Control Flex Pressure Washer

The Kärcher K4 Power Control Flex Pressure Washer is a versatile mid-range pressure washer built for regular cleaning around the home and garden. Delivering up to 130 bar of pressure with a flexible hose for easier handling, it's a strong choice for patios, driveways, vehicles and garden furniture — used more frequently than the K3 but without the farm-grade demands of the K7.

Patios & driveways	Cars & garden furniture
Fencing & garden walls	Regular home use

Why the K4

✓ Flexible hose for easier handling The Flex hose is more supple than a standard hose — easier to manoeuvre around vehicles, furniture and garden features without kinking.

✓ More pressure and reach than the K3 130-bar pressure and an 8m hose give you noticeably more cleaning power and coverage than the K3 — better suited to regular cleaning of larger surfaces.

✓ Pressure control at your fingertips The Power Control gun adjusts pressure directly on the handle — go gentle on paintwork, increase power for stubborn dirt on paths and walls.

✓ Need more power for farm use? The K4 handles regular home tasks well. For tractors, trailers and heavy farm machinery, the K7's water-cooled motor and 180-bar output is the right tool for the job.

Common Questions

What's the difference between the K4 and K3?
The K4 delivers more pressure (130 bar vs 120 bar), a longer hose (8m vs 6m), and a higher flow rate — making it better suited to regular use and larger cleaning areas. The Flex hose is also significantly easier to handle.

Can it clean a patio or driveway?
Yes, it handles patios and driveways well for regular maintenance cleaning. For heavily stained or neglected surfaces, the K7's higher pressure and flow rate will deliver faster results.

Is it suitable for farm use?
For light farm tasks it can manage, but it's not designed for heavy machinery or regular farm workloads. The K7 with its water-cooled motor and 180-bar output is the better choice for tractors, trailers and yard cleaning.

Does it come with a warranty?
Yes. 2-year manufacturer's warranty included. Register on the Kärcher website within 4 weeks of purchase to extend to 3 years.
