This Is a Ball Pit Cleaning Machine

Ball pits--a staple of indoor playgrounds--were invented in 1970 as a children's play area inside an Ikea store in Sweden. They became very popular, despite a reputation as being unhygenic. Adults may cringe at the bodily excretions that may be present in ball pits, but children don't know better or don't care.

One must be very careful to keep one's balls clean. It's not just good business; it's also good manners. Easyfun is one manufacturer of a ball cleaning machine that vigorously brushes, disinfects, and dries balls. They're sucked in through one tube and shot out the other. Although the process may take a few hours, it's a lot faster than cleaning balls by hand. You can see more images of this process at Core 77.
