Arrived safely and on time. Do exactly as described, have used them before. My only gripe is about the bristles, they are not stiff enough to withstand heavy scrubbing that would be required with stubborn stains.
I had one of these brushes supplied when I bought the steamer. I used it to clean the grout on my tiled kitchen floor, It worked a treat bring it up almost like new. I also steamed the tiles using a scrubber attachment. Works very well. A tip for you is to use a wet & dry vacuum to suck up the surplus water as a mop tends to spread the dirty water around. Back to the brushes - they last a long time too.
These are to add to the one brush tip I received with my Karcher Steam Cleaner. The little brush worked fantastically getting into little nooks and crannies but one isn't enough especially if you're working with a greasy kitchen. I found having multiple tips, I could continue cleaning through exchanging the brush when it got clogged with dirt and then soak all the brushes afterwards to get them clean for the next time I needed them.
