A foot pump, also known as a bellow pump or hand pump. It is a manually operated device used to inflate items such as balloons, inflatable toys, sports equipment, and air mattresses. This type of pump works by using a foot-operated bellows to push air through a hose and into the object being inflated. Foot pumps are portable, easy to use, and do not require electricity, making them useful for a variety of applications, especially in locations where power is limited.
