This base is certainly voluminous, but thanks to it, maintenance operations can be comfortably spaced out. It’s simple: once the robot has mapped the home during its first visit, it can be programmed and no longer take care of anything for several days or even weeks (depending on the surface and the frequency of use).
During approximately three weeks of testing, during which we entrusted him with certain rooms in our apartment (approximately 50 m2) which he cleaned one or more times a day, we only filled/emptied the water tanks three times. As for the dust bag, despite our long hair and the presence of two cats, it was far from full.
The base also fills some missing The Empty Wash Fill Dock base also solves some pitfalls of previous robots (S7 and S6 Max V) which we criticized in particular a poorly designed collector with too low a capacity that it was necessary to empty frequently, as well as a water tank too small and also impractical to fill. You no longer encounter these problems with the Empty Wash Fill Dock base since you no longer have to touch the collector, which empties by itself, or the tank, which fills automatically.
Likewise, we regretted not receiving a notification when the water tank was empty. Again, that’s a thing of the past since you receive an alert when the station’s water tank is dry. Among the developments, it should be noted that it is now possible to start a wash only, without suction – it is particularly practical to ensure the elimination of some stains more discreetly (since the noise linked to the suction is avoided) .
A robot that recognizes certain objects
S7 which only uses a LiDAR system, the S7 MaxV Ultra also uses LiDAR, such as S6 MaxV, a dual camera system with object recognition ( a system called Reactive AI 2.0). The idea is to identify them to better understand them. In most cases, in fact, it recognizes the objects it encounters or makes assumptions. For example, it correctly identifies cables, shoes or certain pieces of furniture such as a table and chairs. Sometimes he misses the mark – for example, he thought he recognized a TV stand in our kitchen. When we tested the S6 MaxV, it did not take pictures of objects contrary to what it promised. It’s now solved and the S7 MaxV Ultra does it. Within the complete map viewable on the application, there are icons corresponding to the obstacles encountered. By clicking on it, you can access the captured photograph, as well as a description; for example, when he comes face to face with our shopping cart, he evokes a “furniture likely to jam the device”, described as “furniture fitted with a crossbar, eg. cantilever chair. But above all, it offers an option “avoid not necessary, ignore? “. We can thus let the robot predict that the obstacle is constantly present at this location, or ask it to ignore it if the object is likely to be moved. @JDG
In the end, whether it recognizes objects or not, the S7 MaxV Ultra “sees” them and avoids them, so that it never gets stuck and apprehends obstacles in a relevant way. He is also very careful with the doors and the furniture, which he does not knock, nevertheless cleaning their periphery with care (for example around the legs of tables and chairs). From this point of view, the S7 MaxV Ultra takes a step forward. It combines the precision qualities of the S7 – it covers all areas very well and cleans thoroughly everywhere – with the navigation advantages of the S6 MaxV since it avoids cables or laces which could interfere with the S7. No problem either with animal bowls for example. Note that the S7 MaxV Ultra has a Led torch at the level of its cameras. This allows it to evolve without difficulty in rooms without light or dark environments.
Vacuum and mop functions still as attractive
These two functions had already convinced us on previous models of Roborock; the S7 MaxV Ultra is no exception. The suction can be set in the app to 4 levels (silent, normal, turbo, maximum). In our case, given that we mainly have tiles and parquet floors, the normal level was sufficient, even when our felines had sown a lot of hair. In this mode, the robot is also not very noisy.
For owners of carpets, the recognition is particularly appreciable: you can choose that the vacuum cleaner there automatically increases its suction power, a function that we have tested and which works very well. You can also choose for the robot to lift its mop to clean these surfaces or simply not to climb on them.
Regarding the washing function, like the S7, the S7 MaxV Ultra uses a vibrating mop (known as “sonic”) to scrub the floors. This is more than enough to clean hard floors from everyday stains, even in the kitchen. In addition, after the passage of the robot, the floors are just damp and dry very quickly. We have the possibility of customizing the wash with three intensities of friction available.
@JDG Finally, even if the mop rubs the floors, we cannot speak of washing strictly speaking with clear water. Roborock therefore gives the possibility of using a specific detergent that can be diluted directly in the large water tank of the base. This rather expensive cleansing product is available on Aliexpress.
The possibilities offered by the Roborock application are similar to
those offered with the S7. Many settings are available as well as multiple possibilities for customizing cleaning (washing only, washing and suction, degree of washing and suction power, etc.). The cartography provided is precise; you can cut or merge the parts, name them and choose to clean them or not.In addition to the functions related to the S7, there are icons on the map indicating that the robot has encountered obstacles as well as the photos it has captured of them. Most of the main functions and information are accessible from the home page: detailed cartography, surface cleaned, battery level, cleaning time, complete cleaning or cleaning of a room or area, as well as washing parameters and suction. On the other hand, to personalize the mapping, program the robot, access the cleaning history or information related to maintenance, you have to enter the menus, which are extensive but fairly well organized. Throughout the cleaning cycle, you can locate the robot on the map, see which areas and rooms it has cleaned and follow its path in the home. If the user wishes to let the robot do its work by using the map initially established without modifying it and always cleaning the entire housing, it is possible. On the other hand, if he wants to take the trouble to personalize the cleaning finely according to his needs and habits, he can also do so, even if it requires digging a little into the application.Roborock offers regular app and firmware updates – we received several during our test.
What about the interview? Regarding maintenance, the robot tends to attract dust and animal hair, quite visible on its matte black cover. It must therefore be regularly cleaned with a cloth, as well as its base. Thanks to the Empty Wash Fill Dock station, there is no need for frequent filling of the water tank and emptying of the dust collector every cycle or every two cycles. But that does not mean that we are completely exempt from maintenance.
The maintenance tab of the application gives an idea of the condition of each element and explains how to clean them. Unsurprisingly, the robot itself must be cleaned regularly: rinsing the filter (washing with water recommended every two weeks or so), dusting the sensors, cleaning the side brush (screwed) and the main brush which must be in particular eliminate some hair that can get tangled in it. The latter is easy to access and due to its design (it consists of twisted rubber slats) it does not get dirty very much.
@JDG As for the base, it must also be maintained. You have to change the dust bag when it is full (Roborock provides two), fill the tank with clean water and empty the tank with dirty water. In these cases, the application sends a notification, which is very appreciable. In addition, the light on the base turns red, indicating that an intervention is necessary. You should also clean the charging contacts from time to time with a dry cloth. The base also houses a brush which is used for cleaning the mop – Roborock recommends cleaning it every 6-12 months. Finally, there is a water filter, which must be cleaned “if necessary”. Both are very easy to access once the robot has been removed from its base. But during our weeks of testing, whether it’s the filter or the brush, these elements got very little clogged. As for the emptying of the dirty water collector, even if it is not the most pleasant moment, it is carried out without difficulty. A simple rinsing of the bottom of the tank with clean water is sufficient. The most painful manipulation consists in unclogging the air pipe if it ever becomes clogged (in which case the base must be disassembled from below) but this did not happen to us during our test. @JDG
