Walmart offers the Dyson Tangle-Free Turbine Tool, model no. 925067, for $38.89. Opt for in-store pickup to dodge the $4.97 shipping charge. That's the lowest price we could find by $11. This vacuum attachment is compatible with Dyson upright and canister models from DC23 onwards, except DC24 and cordless models. It purports to release more hair straight into the bin.
