The reference cleans very well, in my opinion, because it is very small but, I ordered a second me. If you have to clean a large window area, a reference is not sufficient, because you'll have to stop in the middle to wash this.!
The cover can be washed in the washing machine, but no fabric softeners should be used because it is a microfiber.
I even waited until he has cost around 8 euros and had to be amazed to find that even 2 were in the package after delivery. !! In this respect, you can not complain, although this was not mentioned separately.
The reference is an original Kärcher, thus it fits exactly on the window cleaner from Kärcher. Cleaning is hereby quite fast out of hand.
