Which of these is the name of a machine used to keep the surface of an ice skating or hockey rink smooth?

I grew up with someone who had the name "Zamboni". When I asked if his family had anything to do with the inventing of the machine he replied "no, my grandfather was a haberdasher". That's when I learned the meaning of that word, 1975!

Let's go Colorado Avalanche!!!

I grew up in Downey, CA. Right next to Paramount. I have been ice skating at a rink in Paramount. I wonder if it is the same?
