Robotic vacuums are great. Stopping every 30 minutes to clean out their bins, not so much. The iRobot Roomba i7+ Vacuum overcomes this problem with a world-first charging station that automatically empties the bin. The dust and dirt go into a disposable bag that holds 30 bins worth of detritus, letting you go weeks without emptying. It also has Imprint mapping technology that learns and adapts to your home's layout, WiFi so you can tell it when and where to clean, and powerful suction that's 10 times stronger than the company's 600 series vacuums.
