Knockoff BN-17 Windups

Barely anything is known about them, aside from what they look like, what they're based on, and some of the color schemes they can come in. Pull them back or wind them up, and the polyester beads inside them should move about.

Most of them have transparent helmets, stickers on their helmets of happy eye expressions, and they hold the handle of a vacuum with both hands. The toys are covered in stickers that mostly say "Robot", and the vacuum end has a sticker on it, which reads "Happy Time".

Two photos of them with clear, colored helmets, show them without beads in their helmets.
