The lines of the two robot vacuum cleaners that compete here are very different. The first, the Roborock S7+ is round and white; the second, iRobot’s Roomba s9+ is black and sports a D-shape, which was historically the trademark of robot vacuum cleaners from Neato, iRobot’s main rival.
The height also differs: the Roomba s9 + is only 9.2 cm thick, when that of Roborock is 9.6 cm, which could prevent it from passing under low furniture. This growth is due to the presence of the Chinese robot’s laser rangefinder, designed differently from its rival. The latter also has the advantage of being supported by a camera integrated into the hull of the device which allows it to save a little space.
Each of the robots is equipped with three direct access keys, accessible from the cover: one to bring it back to its base, another to turn it off or on manually, and the last to carry out localized cleaning. To access the other features, you will have to go through the application, but we will come back to this.
The Roborock S7+ and iRobot’s Roomba s9+ come with a charging base that also incorporates an automatic waste emptying system. Within the base of the Roomba, there is a bag with a capacity of 1.7 liters which accommodates the dust from the waste bin of the vacuum cleaner. As soon as the robot returns to its base and the collector is full, the dust is sucked into the bag. At Roborock, the system is thought out differently since the station is split in two. It has the particularity of declining an emptying with or without a bag. On the one hand, we find the HEPA filtration system to retain pollens and allergens; on the other, the waste container can accommodate the bag (1.8 litres) or the multicyclone filter. In use, the two emptying systems have proven to be very efficient.
Connectivity and app
The applications of the two robots are very complete. Of course, the interfaces offer to start and stop the vacuum cleaners remotely, but also to follow the progress of the cleaning, to empty the waste bin and to organize a cleaning session over the week.
Both devices offer several cleaning levels for a more or less intensive vacuuming session (three on the Roomba s9+, two on the S7+). Additionally, both references allow the creation of virtual beacons that prohibit robots from entering certain rooms or areas of the room. Once the zones have been configured in the application, it is possible to ask these robots to clean a specific room. As you will have understood, the two applications are very complete and offer more or less the same functionalities.
But insofar as the Roborock S7+ is equipped with a double automatic emptying system and that, in addition, it also provides a “washing” function of the floor through its sonic vibration system, it is more complete.
