I purchased this item because the mfr said it would fit ALL Karcher pressure washers up to 2300psi. I purchased this item at the same time I bought a Karcher G2000MK 2.4hp pressure washer 2000psi which does not have a bayonet style pressure gun. DO NOT PURCHASE THESE ITEMS FOR USE TOGETHER. Your pressure washer MUST have a bayonet style gun to attach. As a result, I have no idea if this accessory works well or not as I could not use it for my driveway. Also, there was no manual shipped with the brand new attachement so I spent considerable time trying to find out why it wouldn't attach.
