tenant request for rollers under appliances - reasonable?

[Lisa W.]

Tenant has requested that I provide rollers under appliances (stove, W/D) so she can move them to clean under and behind them.  Claims was not clean when she moved in. I said that appliances are not normally put onto rollers because they are designed to not be moved while in use, and suggested she move them by putting onto a masonite board or SuperSliders.  She replied that she expects me to provide them, otherwise she refuses to be responsible for any damage done to the sheet vinyl floor. In 20 years of managing three units I've never had this come up before.

How would you fellow landlords respond?
