Cleaning robots promise that you will never have to vacuum or mop again. Stiftung Warentest regularly tests what the robots can do on hard floors or carpets, how thoroughly they mop and what they are good at in practice. There are many good models, but the price differences are large: Between 160 and 1400 euros.

Product details
Obstacles such as charging cables do not get in the way of the Roomba j7 Robot Vacuum Cleaner, as it can detect and avoid them in real time using PrecisionVision Navigation.
To do all the work for you, the Roomba j7 Robot Vacuum's powerful 3-stage cleaning system has a lot to offer: 10x powerful suction, a corner and edge brush for walls and corners, and two unique rubber brushes that flex to fit all floors and won't get pet hair caught in them.
In addition to basic and room-to-room cleaning settings, you can send the Roomba j7 vacuum robot to a specific spot, such as in front of the kitchen counter. The robot picks up dirt as it happens, so you can live your life. Thanks to Dirt Detect Technology, the Roomba j7 Robot Vacuum Cleaner detects heavily soiled areas in your home and cleans them extra thoroughly.
Look forward to exceptional and smooth cleaning: The Roomba j7 Robot Vacuum Cleaner learns your home and habits to best fit your life. Enjoy a clean home with hands-free cleaning thanks to your Roomba j7 robot vacuum powered by iRobot OS. The robot adapts to your ever-changing schedule and cleans when you're not there.
Cleaning works so well because the Roomba j7 robot vacuum returns to its base station to recharge when the battery is low. It then picks up right where it left off. Thanks to the iRobot OS Home Intelligence platform, the more you use the Roomba j7 robot vacuum in your home, the better it cleans. The Roomba j7 Robot Vacuum immediately avoids hazards like charging cords, which it detects with PrecisionVision Navigation. It then sends you a photo so you can tell it whether to avoid the obstacle or clean around it in the future.
iRobot gives you as much control over your data as it does over cleaning your home. We respect your privacy and only use information to improve your cleaning experience.
