Cleaning Performance
Suction Power: Reliable Cleaning for All Floors
Both the Roomba J7+ and Roomba J8+ offer 10x the suction of the 600 Series, making them well-equipped for handling dirt, debris, and pet hair across various surface types. Whether you have hardwood floors, low-pile carpets, or medium-pile carpets, both models are engineered to pick up particles effectively. However, the J8+’s AeroForce® Dual Brushes provide slightly better performance, particularly for homes with significant pet shedding or stubborn dirt.
Brush Systems and Pet Hair
The Roomba J7+ uses Dual Multi-Surface Rubber Brushes that work well across a variety of surfaces, effectively pulling up debris and preventing tangling—particularly useful for homes with pets. On the other hand, the Roomba J8+ comes with the more advanced AeroForce® Dual Brush System, which is designed to tackle pet hair even more efficiently and help keep your home cleaner.

One of the key features of both models is the ability to set No-Go Zones using the iRobot Home app. You can customize the cleaning zones for each room and direct the robot to clean specific areas. The Roomba J8+ offers more advanced cleaning management and slightly more precise mapping capabilities, making it easier to target specific messes or areas that need more attention.

In comparison, the Roomba J8+ provides up to ~90 minutes of battery life, allowing it to cover a slightly larger area before needing a recharge. Both models feature the Recharge and Resume functionality, meaning they will automatically return to their charging dock when the battery is low, recharge, and then resume cleaning where they left off.
