If you have a block type plug from a sewing machine you can buy the cheap Dremmel and plug it in to the foot pedal to run your tool! Foot speed control. I have use one to clean up some really crappy parts. I use a cup type brush. I got some of the cheap ones on line and ended up with tiny wires all over my body. Buy good ones but don't expect them to hold up all that well either. It is better to buy a cheap Dremmel tool once than to buy the junk from China and then have to buy another one later.
