I chose the Karcher MV6 pushed by the good reputation of the brand, which I have for many years a pressure washer which I have only praise. Obviously the first shipment left me on my hunger, for the start-up switch of the camera was not working. No switch, no vacuum. But the service impeccable after sales me quickly replaced the culprit and my new vacuum works very well. High suction power adjustable power at will, well thought-out accessories for the moment everything is going well.
