Karcher K4 Premium Full Control Home review

Reviewed

The £330 Karcher K4 Premium Full Control pressure washer is supplied with a T350 patio cleaner and detergent, five-year warranty and hose storage reel. It has an innovative trigger gun that's designed to help you choose the right spray strength for your surface. But does it help? Our expert used this pressure washer on a driveway and decking to bring you her first impressions.
