Walmart offers the Dyson DC35 Digital Slim Multi Floor Cordless Bagless Vacuum Cleaner, model no. 210001-01, in Origin White for $169 with free shipping. That's tied with our December mention and the lowest total price we've seen for a new model without rebate hassles. (Outside of the deal below, it's a current low by $51.) This bagless vacuum features a detachable long-reach wand, motorized floor tool, and dual power mode.
A close price: Target via eBay offers it for $169.99 with free shipping.
