The two robots in this duel are similar in many ways. Round in shape, they have similar dimensions and are both equipped with various sensors including a laser rangefinder to be found on the top, but also a set of cameras and lasers on the front to locate and, in theory at least, identify some hurdles. However, Roborock completes this set of small LEDs supposed to allow the S7 MaxV Ultra to use its camera even in the dark, when that of Xiaomi is no longer able to recognize the slightest obstacle.
Other small differences are to be noted at the level of the brushes, Roborock having made the choice of all-rubber, or even the water tank, inaccessible at Xiaomi, but the most notable are of course to be found on the side of mops and resorts.
The S7 MaxV Ultra inherits the sonic vibration mop from the S7, while the Robot Vacuum X10+ has two small round mops that it can drive at 180 rpm to polish the floor. Good news, however, both models have a mechanism allowing them to lift their mop(s) a few millimeters once on a carpet. They can thus carry out a complete cleaning of the house in one pass, without the risk of soaking the carpets, provided all the same that they do not have too long hairs.
On the side of the stations, the same functions are more or less offered since both are able to empty the collector of their respective robot, to wash its mop(s), but also to fill its water tank – in addition well sure to charge it. Roborock has however chosen to align the different compartments necessary for these functions, while the dust bag takes place under the water tanks at Xiaomi, with a more vertical construction. The S7 Max Ultra station is a little lower, but takes up a little more floor space.
We also find the lid system adopted by Roborock to enclose the dust bag rather impractical; we happened to get one end stuck several times during our test, which breaks the hermetic enclosure and reduces the suction power. The robot’s collector is then no longer emptied correctly.
Connectivity and app
The Robot Vacuum X10+ is controlled with the Xiaomi Home application, which can also be used with most Roborock models. However, the S7 MaxV Ultra is an exception and requires the use of its manufacturer’s application. Overall, both offer very similar functionalities, with customizable maps and the possibility of saving several for possible floors, adjustment of suction power and flow rate. water, or even the possibility of scheduling cleanings on different days of the week.
Roborock has nevertheless made the effort to push the integration of the front camera of its robot a little further than Xiaomi. The various obstacles identified during a cleaning are added to the map and it is also possible to obtain live video feedback to monitor what is happening in the house.
