The D4 will also return itself to its charging base whenever the battery gets low, so you never have to worry about it going dead. The vacuum works with Amazon Alexa and Google Assistant, as well as Apple Watch, Android Wear, IFTTT, and Neato Chatbot for Facebook. The Neato D4 also features a combo brush and a high-performance filter. Thanks to its square design, that brush is 70% larger than round vacuums, and of course, means it can get into corners that other models can’t. As mentioned, the last time the Neato D4 went on sale was in September, when it was priced at $299. That means this latest saving is a whole $50 more off compared to the previous reduction, meaning there’s never been a better time to snag.
