Flotex is that stuff that's something like a cross between toothbrush bristles and velour on a rubber backing, right?
We had it in the kitchen one of our houses when I was younger, and it didn't stay long - it caught every bit of dirt and fluff and held on to it tight.
got the sample of Flotex flooring - less than 24hrs after ordering!
I like it - my wife says 'disgusting' (in reference to it being 'carpet')
