Inside a faulty Kärcher window vac.

I was sent this Karcher window vac by Chris and Mandy. It had suddenly stopped taking a charge.
These things are basically window squeegees with a vacuum unit built in so they can suck the collected water into an internal storage chamber.
Quite an interesting design. Many of the components clip together very snugly with injected seals that also extend to provide support for the ends of the lithium cell.

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
