What treatment for linoleum floor?

You don't need to do anything to it except sweep and mop it. I strongly recommend NOT using paste wax or Mop&Glow on it. They both leave a residue that attracts dirt and do nothing for the vinyl flooring. You have vinyl, instead of old fashioned linoleum. Even the cheapest vinyl has multiple layers of color covered with a protective layer. I'm sure this is cheap vinyl, probably much lower quality than what you would use in your house. But it still should last 10 years or so with basic cleaning.
