If you don’t mind refurbished, and you shouldn’t, Dyson’s AM09 Fan Heaters are priced to move air at $220 today only. Three colors available.
It only took them 16 years but Dyson has created a Roomba competitor. It promises "the most powerful suction of any robot vacuum" and comes equipped with 360-degree camera to help navigate. You know it's futuristic because they used a man with a British accent to narrate the demo video.
