The Apollo 11 Command Module was equipped with a pair of vacuum hoses and brushes for use in conjunction with the LM Suit system exhaust. The astronauts used the vacuum to remove as much lunar dust from their spacesuits as possible before returning to the Command Module.
This brush was transferred to the Smithsonian along with the rest of the contents of the Command Module in 1970.
This object is on display in Human Spaceflight at the Steven F. Udvar-Hazy Center in Chantilly, VA.
