I don't think they sell them anymore ? but i have one which i was going to sell but i saw a machine that looked very similar to it used for granite polishing i think anyway as i am planning on doing a hard floor course soon i decided to hold on to it until i can find out if it will be any good to me in that sphere.
are they any good ? not for real mingers but great for doing stairs in houses where the carpets are clean and just need a freshen up. its quick and the customers like to see you using a machine on their carpets
