Looks like I managed to fix a self standing vacuum cleaner (is that the right name?). The vacuum would run and pull dirt, but the brush didn't turn and there were no lights.
The reason was simple: super cheap cables got torn off, I had to replace them and solder them again.
@stfn looks like a Bosch
@arek Electrolux. Unless you're talking about me being a boss
@stfn nice thinkpad
