Hayneedle offers the Dyson V6 Origin Cordless Stick Vacuum in Blue/Silver for $159 with free shipping. That's $6 under our June refurb mention (this one is new) and the lowest price we've seen in any condition. (It's the best price we could find today by $20.) It features a motorized cleaning head, push-button bin emptying, and up to 20 minutes of cleaning per charge.
This simple preventive measure takes just seconds to perform.
