Kärcher K 4 Power Control Flex Pressure Washer
Corded electric
Overview
The Kärcher K 4 Power Control Flex is the sweet-spot model for many households. It reaches 130 bar and 420L/h, but the important feature is control rather than just peak pressure: the Vario Power lance and trigger-gun display make it easier to match pressure to the surface. Kärcher rates the machine at around 30m²/h and supplies an 8m PremiumFlex hose, dirt blaster and Plug 'n' Clean detergent system. The water-cooled motor is aimed at more regular use than entry models. At 12.1kg it is a proper wheeled machine rather than a grab-and-go compact washer.
