Excelente producto a muy buen precio

Um Terrassen- platten nebst Unkraut zu säubern nicht optimal geeignet, es baut sich ein sehr geringer Wasserdruck auf, welcher nicht mal ansatzmäßig dem genüg, was die Düse beim Kärcher liefert. Wollte, dass es nicht so spritzt , das ist funktioniert auch! Denn es spritz nicht, aber es säubert auch nicht!! Hier sollte man sich entscheiden soll es nicht spritzen oder soll es säubern!! Beides erfüllt das Gerät nicht!!

I used it on an overdue paving job, and it did a great job of cleaning. The thing is to take your time and let it do it's work. Well pleased with the outcome.

With the mixed reviews I was somewhat skeptical but decided to give it a try with my five year old Karcher K 3.540 power washer. I wanted to clean about 350 square feet of paver patio and about 100 square feet of brick on the front porch floor. The paver patio was dirty and stained with lots of dirt and dead vegetation in-between the pavers. The brick porch was dirty with hundreds of dried earthworms from a previous windy rainstorm. I did not have any mildew or algae to deal with.The unit assembled easily and I only had to change the nozzle tips to the green set since my washer only puts out 1.5 gpm. One note when changing tips. They are keyed, so you need to rotate them until they press into place. If you don't have the key-way lined up, they won't fit. Took me a minute or two to figure that out. Once assembled and hooked up to the washer, everything was easy from that point onward.The power head glides easily over the surface and there is no splashing or blow back. You can see the results immediately and even with the flood of water, it is easy to see where you have cleaned. Some stubborn dirt took multiple passes to remove but it all came clean. I worked in sections and after each one I used the washers power wand to push all of the dirty water off the patio and into the grass. This also allowed me to work on any stuck vegetation between the pavers. Took roughly 90 minutes from setup to completion for the patio. The porch was even easier as the bricks were fully mortared with no vegetation to deal with. The bricks came clean, the mortar came clean, and overall it looked great. One interesting fact. The power wand alone had a tough time with the glued on earthworms. But the power head with its rotating nozzles was able to remove them with just one or two passes.Some have commented that their unit failed after a few uses. Time will tell if I see the same issue. But even if it only lasts for 3-4 cleanings, the money saved by not hiring a professional easily pays for the cost of a new unit. So even if I have to replace it every year or two, I still come out ahead cost wise. And the time saved using this device as opposed to just using the power wand with its two inch wide spray is icing on the cake.Very happy I purchased this!
