What method of Carpet Cleaning can be done without damaging the paint art?

I will arrange carpet cleaning for a client who has a number of works of art paintings in your home. Is there some carpet cleaning method that is safe to use to avoid (I fear that the steam cleaning products chemicals can damage the artwork), or simply move it all before you clean the carpets?

A steam cleaner professional service pumps in his van, so there is no steam or chemicals of concern.
