'Zamboni' is the name of the machine that cleans the ice at a hockey rink or skating rink. I think that 'Zamboni' is the name of the man that invented the machine. There is a driver who drives the Zamboni around the ice.
This blog is mainly to explain a different English language expression every day. Sometimes I post other stuff. I also have a YouTube channel which is mostly about computer software: https://www.youtube.com/englishspacedog
