Do you want to put a finish on a large floor? What you need is a wax or polish applicator. They are tools that have a long handle that you fix a cloth to the bottom of for polishing your floor.
Well you can easily make your own. Take your vacuum cleaners wand and wide nozzle, safety-pin a terry cloth rag around the nozzle and, voilà you can polish your floors fast!
It does a fabulous job and it is very inexpensive.
