Amazon offers the Dyson Tangle-Free Turbine Tool Vacuum Attachment for $34.96 with free shipping. (Walmart charges the same price.) That's tied with last week's mention as the lowest price we've seen. (It's the best deal now by $4, although most stores charge around $70.) It's compatible with all Dyson upright and canister vacuums from DC23 onward (except DC24 and cordless models). Features include elliptical counter-rotating heads with integrated brushes and an articulating base plate.
