Dyson via eBay offers the factory-refurbished Dyson DC23 Turbinehead Canister Vacuum Cleaner in Purple (pictured), Yellow, or Blue, model no. DC23TH, for $169.99 with free shipping. That's the lowest total price we could find for a refurb by $30, although we saw one for $10 less in September. Features include a turbine head with air-driven brush bar, clean air exhaust, and washable HEPA filter. A 6-month Dyson warranty bundled with a 2.5-year ABC Vacuum warranty applies for a total 3-year warranty.
