Walmart offers the Dyson Tangle-Free Turbine Tool Vacuum Attachment for $30.43. (Amazon charges the same.) Opt for in-store pickup to avoid the $5.99 shipping charge. That's $5 under our mention from three weeks ago the lowest price we've seen. (It's the best deal now by $40.) 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.
