I brought my first Karcher pressure washer in Germany in 1992 and it lasted nearly 10 years and was excellent. Then I made the mistake of replacing it with one of the cheaper Karcher washers, which just lacked the necessary pressure to thoroughly clean everything. I got rid of it and brought a K 6.85M and normal service was resumed. If you want a decent pressure washer, with plenty of power, this is the one to buy. I have purchased most of the various accessories over the years and some are better than others. Personally, I think the extension lance, rotary brush and the patio washer are the best. Dilute the cleaning fluid 50/50 with water and it works just as well. Enjoy!
