Take the time to research the page and evaluate which robot is best suited for your needs!
iRobot Roomba S9 Plus
Roborock S7+
iRobot Roomba S9 Plus
Compared to its predecessor, the iRobot Roomba i7+, the Roomba S9+ has undergone several significant improvements, including a new D-shaped design that allows it to access tight corners and hard-to-reach places more efficiently. A previous problem with Roomba models was that the brushes spun too quickly, often resulting in the dirt spreading instead of collecting up. On the Roomba S9+, this problem has been solved by having the brushes rotate more slowly, increasing its ability to efficiently collect dirt and debris.
Another noticeable improvement is the dual brush on the underside of the Roomba S9+, which has been moved forward and widened. This causes fewer hairs to get stuck and makes it more effective at cleaning even thick carpets.
The Roomba S9+ uses a navigation technology called VSLAM (Visual Simultaneous Localization and Mapping) instead of LIDAR, which is used by many other competing robotic vacuum cleaners. VSLAM uses a built-in camera to map and navigate your home. One advantage of VSLAM is its ability to handle situations where obstacles have fabric hanging down to the floor, which LIDAR can sometimes have difficulty detecting. However, VSLAM is dependent on the lighting conditions in your home, and it may be less effective in dark environments. A combination of both technologies, VSLAM and LIDAR, would perhaps have been an optimal solution.
It is also worth mentioning that iRobot, the manufacturer of the Roomba, is now owned by the tech giant Amazon, which acquired the company for about $17 billion. This acquisition has strengthened Amazon's presence in the smart home market and positioned them as a leading player in the sector.
Roborock S7+
The Roborock S7+ offers an impressive set of features that will definitely enhance your cleaning adventure. This robot vacuum cleaner is equipped with advanced technology, including Laser Direct Structuring (LDS) mapping, self-emptying, mop function, vibrating mop, automatic mop lift, dedicated app, scheduling, voice control, zone control, multi-floor support, room control and no-mop zones.
An interesting aspect is that you have the option to buy the Roborock S7 without self-emptying at the beginning, but if later you wish to upgrade your experience, you can easily do so. It gives you the flexibility to customize your device to your needs over time.
The Roborock S7 excels especially when it comes to mopping floors. It performs more mopping rounds with high precision compared to its competitors, resulting in a noticeably cleaner surface. Its built-in sensor and foldable mop also ensure it avoids mopping on carpets, which is a smart feature to save time and energy.
It's important to note that the Roborock S7 has a feature missing from its predecessor, the Roborock S6. It lacks ReactiveAI Obstacle Avoidance, which means it can sometimes have difficulty handling larger objects on the floor that it cannot soak up.
It's also worth mentioning that Roborock has three new products in the pipeline in the S7 series. As soon as these are launched in Sweden, we will review them carefully to evaluate if they deserve a place on our list of recommended robot vacuums. The new models promise an even more powerful suction power as well as the long-awaited ReactiveAI Obstacle Avoidance feature, which could make them even more impressive than the Roborock S7. We look forward to seeing how these new supplements perform in the marketplace.
