Rated 1 out of 5 by from Can't use without add on extras Bought this a week ago and haven't been able to use it yet. Karcher are keen to promote their machines can run off a water butt without mentioning you need to buy a special hose which does not come with the machine. They also fail to mention that the max suction height is half a meter, who has a half meter water butt?? You can't order the hose from their website because of "the current situation". I rang their helpline and understandably there is a long wait for an answer due to "the current situation". During the wait they tell you there is an online chat option, there isn't. When they did answer they said they couldn't order the part or give me a price, due to "the current situation", but they would have to give my details to the order team to ring me back. I could see a theme developing here. Nobody rang back. After several phone calls and several false promises that someone would ring me back I finally got through and ordered the part only to be told it was out of stock! I should get it in the middle of June but I don't hold out much hope. My one star rating is not for the machine as I have no idea how it performs yet but for the lack of infor pre purchase and the lousy customer service post purchase.
