Yes, You Actually Do Need a Good Vacuum — Here's Why

Robot vacs have been around for two decades, but the new generation is smarter than ever. Take this Neato D8 Intelligent Robot Vacuum Wi-Fi Connected with LiDAR Navigation ($350), for example. It uses laser technology to scan your space, which helps the vacuum navigate your home precisely. Like a Tesla, it receives software updates wirelessly; and with the MyNeato app, you can decide exactly where it does (and doesn't) go. Clever indeed.
