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
Wi-Fi-connected robot vacuum cleaner that detects and avoids obstacles like pet waste and charging cables to get the job done.
Deliberately avoids pet accidents – we guarantee it. Only iRobot offers you the P.O.O.P. (Pet Owner Official Promise). You can trust that your j7/j7+ will avoid pet waste, or we will replace it for free. Offer valid for one year from purchase and covers only the replacement product. Valid only for solid cat or dog waste. Additional terms apply – see iRobot's Pet Owner Official Promise for complete details.
Object detection and avoidance. Obstacles like pet waste, charging cables, and shoes won't stop the j7/j7+ from finishing the job, as it uses PrecisionVision Navigation to recognize objects. When it sees them for the first time, it sends you a photo so you can tell it to avoid or clean around the obstacle in the future. It not only learns your home; it responds to it in real-time.
Automatically empties its bin with a sealed bag system. Forget about vacuuming for months with the Clean Base Automatic Dirt Disposal, which allows the Roomba j7+ robot vacuum to empty itself for up to 60 days. Sealed bags capture 99% of pollen and mold. Dust stays out of sight, and your hands stay clean.

The robot vacuum and suction station are relatively noisy. The iRobot recognises steps well and turns around immediately. If a room is clean, doorsteps up to 2 cm high do not prevent it from continuing its work. Inaccurate navigation in poor lighting conditions.
- High suction power
- Suction station
- No wipe function
... The Roomba j7+'s suction performance is impressive: It performed slightly better than the Roborock S6 MaxV on both hard floors and carpet. However, it is also a little louder. In terms of room coverage and orientation, it is on a comparable level, but bumps into furniture more often and a little harder...
