If you’ve been waiting for a good robovac deal, get a load of this 40% markdown. This top-rated model is slim enough to glide under sofas and clean other often-neglected areas in your home that could use a de-dusting, and to make things extra hands-off, you can control all the action through the app. Thanks to the M210’s built-in infrared sensor, this little robo-pal can automatically detect walls, stairs and more, without damaging furniture or falling down stairs. It can also run for up to two hours per charge.

It’s only been on sale for a few bucks less in the past, so we’d recommend zapping it up while it’s under $100.
