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.

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.
