If you’re all about robot vacuums, the new Neato BotVac is one to check out. This Wi-Fi enabled device connects to your Android smartphone and uses SLAM technology to avoid obstacles, navigate from room to room, and vacuum in methodical patterns rather than just bumping around — returning to its charging base when needed. Users can control the Neato BotVac straight from their device, directing as you desire, or activate the unit remotely while you’re away at work to start cleaning before you get home. A handy piece of tech to have around the house, but it definitely comes at a steep price.
