You can also use industrial mop bucket with a wringer. Put the wringer on backwards so the run off goes our of the bucket in the bucket have rinse water. It’s not super dry but makes for easier hand wringing.
Good point with the wires, my bad I assumed everyone knew you need much heavier gauge wire with dc currents and to keep the distance from source as close as possible. If we ran on dc like Edison wanted each block would have its own generation facility because of losses over distance. Thx mouse wizard for pointing it out.
