I was vacuuming the back of my fridge, and my vacuum cleaner stopped working. I switched it off, moved it over the countertop and when I was trying to power it on it didn’t work at all. Initially, I thought that the power button stopped working and was trying to disassemble the handle but thanks to this video I realized that probably it was just power connection was lost somewhere.

So I disconnected the hose that has wire to the handle to allow the power button to work. Then I pressed every contact with the screwdriver to make sure that every sping was working and viola, it came back to life.

I hope it helps someone.
