I guess you are asking for something to get you close to the base boards. When we used RX20's and the RotaVac we wanded the edges first. They now have tools like a 4 inch wand just for edging or others have a wand with a pressure jet mounted on a large crevice tool. I don't knoow if Greenie has these or not. If not I am sure JonDon or InterLink has them.
