Like Rick said, the area near the baseboard is pretty much clean.
We vacuum the edges and have used this brush with great results. On accounts that we don't do the nightly janitorial cleaning. (On a monthly bases we vacuum the edges with our Pro backpack and 3inch head works great on the sides of cubicles too.
