The latest K4 is fitted with Karcher’s innovative Full Control feature, which is a lance-mounted pressure display. LED images for shampoo, soft, medium and hard tell you what the current lance pressure is safe to use on. We found our full power fan was higher than recommended for cars (classed as medium). Tweaking it down slightly hardly impacted on cleaning speed, but reassured us no damage was being caused. Clever as the feature is, though, what sets this pressure washer apart is its excellent cleaning power and – typically for Karcher – its simple but effective design. This K4 stands out as our winner.
