I vacuum as far as I can reach under our bed (king) with the regular vacuum. The cats (2) sleep under our bed. I was looking for something, and grabbed a flashlight, and looked under the bed. I was shocked. A LOT of hair had accumulated under the center, where I couldn't reach. I have a smaller wand type vacuum, that lays almost flat, and has a large extension wand. I got enough hair out from under there, that I could have built 8 cats. Now that I'm aware, I'll have to do that more often.
