I tried it Ron, and they don't work so well, at least not for me. When I first purchased my Rotovac, I took it to my parents house to do their tile, and we weren't impressed.
I don't know if it's a weight thing or what, I always whip out the 175 for tile. Perhaps the 360 does a better job than the original, I don't know.
But those brush heads do a great job scrubbing carpet, and the weight issue works in favor of the Rotovac while doing steps. Any heavier, and you'd give yourself a hernia!
Another thing about the brush heads on the original, they only squirt and scrub, no vacuum ports like on the 360.
