Hi Jim
We buy the unger cone adaptor from wintecs, we drill and screw this onto a 5 metre Harris pole, from wintecs as well we use the unger flat mop head that screws onto the adaptor along with the microfibre pads, a spray bottle with some pure in and you're away, we get the Harris poles from amazon, they're about £16 delivered, we use this on most of our internals and get good results, I'm assuming if there is carpet down etc that this is a maintenence clean rather than a first clean..?
