It seems that a Chinese inventor has come up with a hair washing machine. Looking at it in action, all I can think is that a conventional shower would be a whole lot less fuss and bother, and much more efficient!
Also, the opportunities for mischief by naughty friends or family members are almost endless. Think of tying the user’s victim’s shoelaces to the retaining device while he’s upside down, or dripping something unpleasant into his breathing tube while he’s inverted. This has the potential to make washing one’s hair a survival experience!

Hairboarding!
Maybe he can sell 'em to the Inquisition.
Having watched someone get scalped, hair and any mechanical device that spins that touches said hair is not a good combination.
