As one of its early Prime Day deals, Woot via Amazon offers Prime members the refurbished Dyson Ball Multi-Floor Upright Vacuum for $149.50 with free shipping. That's $50 less than our mention last month of a new one and the lowest price we've seen. (It's $100 under the best price we could find for a new one today.) It features a HEPA filter, self-adjusting cleaner head, and 35-foot cord. Deal ends today.

Note: A 6-month Dyson warranty applies.
