Speaking of, you can pick up the Eufy Robot Vacuum Omni C20 at Amazon and Eufy for $399.98 ($300 off), matching its all-time low. The Omni C20 is one of Eufy’s newer vacuum and mopping combo units that offers several automated cleaning features to make your life easier. While we haven’t had the opportunity to test the Omni C20, our experience with Eufy robovacs has been generally positive. We chose the Eufy X10 Pro Omni as the best midrange robot vacuum / mop combo, and the Omni C20 offers a similar suite of features. However, the Omni C20 doesn’t support obstacle avoidance, which means it may run over wires, socks, toys, and even pet messes.
