buy the unger flat head mop, cone and some pads from wintecs , get yourself a 5 metre Harris pole from amazon, drill and self tap the cone onto the Harris pole and off you go, we use these on our commerciasl and they come up great, all you need is a bottle of pure water, it's a very cheap basic version of the easyshine, only good for maintenence cleans, prior to this we use a vice versa or wagtail on the first clean
hope this helps
