It's their newest, fanciest, most spectacular robot vacuum, and will set you back an eyebrow-raising US $950. The i7 includes both iRobot's premium i7 vacuum, and a " " in the form of a docking station that will empty the i7's dustbin into a larger disposable bag. This means that you can go much, much longer between maintenance sessions, and it's entirely possible that the i7 can operate in your home autonomously for weeks or even months, keeping your floors clean without you ever having to think about it. While the dirt disposal dock is the most visible new feature, we've also been looking forward to the persistent maps that come with the i7. These are maps that stick around between cleaning sessions, allowing you to give the robot specific instructions like exactly where and where not to clean, and while the dirt dock is cool, persistent maps are even cooler, with an enormous amount of long-term potential. The i7 is, without a doubt, extraordinarily capable, but it's also very, very expensive.

Jennifer Jolly puts top robot vacuums to the test. Robot vacuums have been promising to do our dirty work for more than two decades now, but rather than provide the hassle-free cleaning help of our dreams, some just suck – and not in a good way. Sure, early models devoured surface detritus, but often left a trail of half-eaten dirt-crumbs and dust-bunny bits while they crashed into walls and furniture legs with about as much grace – and overall success – as a drunk person wearing a blindfold. But sweeping changes are underfoot in the robot vacuum world, with a few of the latest models inching closer to a kind of Rosey from "The Jetsons" reality than ever before. For instance, most robot vacuums come equipped with Wi-Fi now, so that you can schedule and control them from an app on your smartphone.

Now that Google is poised to have multiple Home speakers in its lineup, you're going to need a better way to manage those speakers -- and thankfully, it's already here. Google has revamped the Home app (currently just the Android version) with not only a fresh look, but support for assigning speakers to specific rooms. The tweak should make it easier to control specific speakers and even whole environments. If you want to stop music playback in the bedroom at the same time as you shut off the lights, you can issue a single command to do it all. Although you certainly weren't forced to use one Home speaker before, it's now crucial that Google knows just which device you're referring to.
