Groupon offers the refurbished Dyson Multi-Floor Upright Vacuum Cleaner, model no. 206900-01, for $199.99 with free shipping. That's tied with our March mention as the lowest total price we've seen in any condition. (It's $199 below the best price we could find for a new unit today.) It features radial root cyclone technology, a HEPA filter, self-adjusting cleaner head, reconfigured brush bar, and 35-foot cord. Deal ends April 28.
