Somehow, iRobot keeps improving its vacuums. The iRobot Roomba s9+ Automatic Dirt Disposal Vacuum not only dumps its own dirt but also communicates with a mop. This smart vacuum cleaner uses Imprint Link technology to communicate with Braava jet m6 robot mops. Once the Roomba s9+ completes its vacuuming, it will let the Braava mop know to begin mopping. You can come home to sparkling clean floors without lifting a finger. This automatic dirt disposal vacuum isn’t an inexpensive floor-cleaning device, but it sure does its job well. iRobot even changed this Roomba vacuum’s shape by flattening one side. This ensures that you’ll see cleaner lower walls and corners. Because those pesky spots sure can be bothersome when left dirty.
