Walmart offers the Dyson Tangle-Free Turbine Tool Vacuum Attachment for $35 with free shipping. (Amazon charges the same.) That's tied with our mention from last month as the lowest price we've seen. (It's the best deal now by $35.) 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.
