I don't remember very much about this movie... possibly a TV show... but it was about a family that lived in this house that was haunted by a ghost... and I remember the ghost looking sort of like Slimer from Ghostbusters... and all I remember was that they vacuumed the ghost to get rid of it... sorry I don't have more info... Any help will be greatly appreciated!

That happened in the live version of Casper the Friendly ghost with Christina Ricci. That was a 90's movie. Maybe that's it.

I thought it might have been it, but it was definitely older... the vacuum was older... aargh! Lol driving me crazy... thanks for the help though...

I think it's Mr. Boogedy

The vacuum scene is in this movie too
