Faucets are services which give away free Bitcoin. However the amount of Bitcoin given away by faucets is so small such that the amounts are basically negligible and worthless.

Faucets are not miners nor are they related to miners(although miners could run faucets if they so choose). Rather they serve as websites where the faucet owners can place a large number of advertisements and still get people to visit their site and view those ads. In this way, the site owner can earn a significant amount of money from ad revenue while spending very little by giving away money via the faucet.
