We just removed two old vinyl floors and subfloors today from our kitchen. We were planning to use a circular saw to rip channels with which to pry up the floors. However, to our surprise, all we needed was a hammer, and chisels and pry-bar to lift up the old flooring. It came up easily but we spent hours pulling up staples with a vise-grip.

Good luck with your floor!
