The Kärcher Hard surface cleaner T-Racer T 350 is a great addition to the normal Kärcher. He is super processed and works - as usual from Kärcher - very good.
Unlike the spurting forward high-pressure cleaners of the 350 T caused much less dirt on the wall, what I really think that's great :-)
The supplied extensions can work with the T 350 also quite comfortably without having to bend your back.
He is also quite universal use (it can be operated from K2 to K7).
The result is great for normal to medium soiling. In very stubborn stains should still specially admit detergent or just using the rotary nozzle.
The T 350 is not cheap, but it's worth it! Also, because it cleans slightly faster than the rotary nozzle ...
