The Karcher K 4 WCM Flex Eco Booster Car and Home Pressure Washer is a 130 bar machine for home owners. It comes as a bundle for cars and gardens. A water cooled motor gives it a longer working life. Karcher says it is made in Europe.
Pressure runs from 20 up to 130 bar. Flow is up to 420 litres an hour. Area performance is 30 m² an hour. The Eco Booster lance gives 50 percent more cleaning performance than standard flat jet nozzles. A Dirt Blaster lance handles stubborn patio and driveway dirt.
The kit has a T 5 patio cleaner and a rotating wash brush. There is a foam jet with a 0.3 l bottle. You also get 1 l bottles of car shampoo and stone and facade cleaner. The 8 m PremiumFlex hose gives good reach round a car.
An integrated water filter protects the pump. Accessories store on board. The Quick Connect System makes swaps fast. It weighs 11.8 kg without accessories. The Karcher Home and Garden app adds guidance for each job.
