Karcher holds the top spot when it comes to pressure washers because of its reputation as being the best. It dominates the market, fighting off competition from both the inexpensive budget brands and the professional premium end of the market.
The Karcher K4 range is renowned for its impressive cleaning performance and the robust, long-lasting design of each of the four K4 models. The key to both the range’s longevity and cleaning capabilities is the powerful water-cooled motor – unique to Karcher – which has been designed to be more durable than standard water pressure motors.

It’s compact enough to be stored under the stairs or in a small shed or outbuilding, with on-board storage for cabling, hoses and standard accessories.
