Karcher has a great competitor

Hyper disappointed but identical glass cleaner Karcher brand after 6 uses merely traces, I chose (to give to my daughter), I kept it I am in my sixth use and so far no trace;
I use unlike Karcher clear water without any product with a microfiber and just after I aspire;
5 stars for ease of use
5 stars for autonmie more important than Karcher
5 stars for the unit's maintenance facilié
and the 5 stars for instant results but that this can change, I remetrai a comment if it occurs
Basically I wait a bit before buying one my daughter who has a Karcher she no longer uses and for now I would recommend this product to a friend
