welcome to the forumMost times they dont want me to move the sofa and they end up moving the stuff themselves. In any case moving things doesnt take a lot of time. Customers for me have been very cooperative in this area.
I agree with Diego,. this is what i'm usually doing too..Well this applies to tile and grout (which as you know Nathan is very common in the new subdivions) - I tell the customer we don't move small knick knack breakables like vases, pictures, lamps, electronics , appliaces or big heavy big cases or shelving.
Everything else we can usually move. There are teflon sliders you can put under the furniture usually.
Carpet cleaning is a bit easier because you move something real quick, clean under it and then move it back. But with tile and grout you need to work with an area for an extended period of time, scrubbing, letting chemicals dwell, etc.
hope that helps
