After I got the Kärcher, the part ;-) was operational within 10 minutes. First I tried the hard surface cleaners and have to say, the terrace has become picobello blank. The tube cleaning system I jokingly held in the Gulli, off they went like "Schmitz cat" ;-) car brush is fine and was immediately used by the son and classified as work much easier. All in all, top quality at a reasonable price. Within a small radius are 5 DIY with me. Had notice that there this Kärcher Set K 2.980 M between 70-150 !! Euro was offered more expensive. As I said, highly recommended.
