Dyson offers its Dyson V7 HEPA Cordless Stick Vacuum for $189.99. Plus, auto-register your product to receive two additional tools for free. (Registration is automatic, and you will choose your free tools in cart.) With free shipping, that's tied with our mention from a week ago as a savings of up to $250 including the tools, and the lowest price we could find. It features up to 30 minutes of fade-free suction and includes motorhead, combination, and crevice tool attachments.
You very likely are putting your laptop battery into an early grave.
