Why The Hell Does This Vacuum Scream Like A Human?

The clip shows a young man hoovering a chest of dresser drawers but as the vacuum cleaner’s head passes by the small gaps between the drawers a sound that can be best compared to a male human in pain can be heard.

To best demonstrate the odd noise the man passes two gaps between the drawers and goes back and forth, eventually holding the hoover over a thin crevice for a few moments, creating a longer screeching sound.
