Convenience of use

The Q7 Max + looks like many other models in the Roborock catalog, excluding the E series – the models of the latter do not have a laser rangefinder. We find one on this model. Slightly advanced in relation to the center of the shell, which it rises almost 2 cm above (the total height of the robot reaches 9.6 cm), this rangefinder makes it possible to map the different rooms of the home and works with various sensors present on the lathe and the underside of the robot so that it moves without (too) much trouble.

However, the system is not as sophisticated as that of the S7 MaxV Ultra which includes, in addition to the rangefinder and sensors, a camera positioned at the front in order not only to detect, but also to identify certain obstacles. A function that is also found on the Roomba j7+ and the JetBot AI.

In addition to the rangefinder, a few buttons sit on top of the Q7 Max+ in order to access its main functions without going through the app (cleaning, return to base, etc.). Roborock also allows you to lock them to prevent a child or animal from activating them by mistake. On the other hand, a semblance of a handle allows the rear part of the hull to be lifted to access the collector, here combined with the water tank provided for the washing function.

Roborock indicates that bringing the two elements together has notably allowed him to increase their capacity, which seems especially true for the water tank. This can hold 350ml, compared to 300ml in the S7. The dust bin has a capacity of 470 ml against 400 ml for the S7 Max V Ultra, but that of the S7 is identical.

In both cases, it’s relatively comfortable, especially since the automatic emptying of the Q7 Max+ actually avoids having to deal with the dust container. Roborock’s second argument also falls flat for this reason, because it’s about having only one element to transport to empty and fill. We can certainly hear it for the Q7 Max without a vacuum base, but we would have preferred to see a hatch system arrive preventing the exit of waste on the dust container when it is handled without too many precautions.

On the underside of the Q7 Max+, two brushes are worth noting. The main one, in the center, is a rubber roller that rotates to drive the dirt into the suction mouth. Added to it is a small rubber brush, too, but in the shape of a star which turns on the side to fold the waste towards the center. A mop can be added on the back, but its support does not vibrate like that of the S7 and S7 Max V. It only scrubs the floor at the speed of the robot and therefore you should not expect a miracle on stubborn stains , even if the manufacturer puts forward a constant pressure of 300 g on the ground.

The Q7 Max+ comes with a charging station, but its own also works to empty the collector. To do this, it includes a ramp by which waste and dirt are sucked up to arrive in a bag housed in the upper part of the station. A lid provides easy access to this 2.5L capacity bag. According to Roborock, it can hold enough dirt to only have to change it once every seven weeks.

As a result, this station is much larger than a simple charging station. Its more than 40 cm in height will in particular prevent the vacuum cleaner from being hidden under furniture when it is not in use.

Connectivity and app

The Q7 Max+ connects via wifi via the Roborock application, which then allows it to be controlled remotely. The pairing went smoothly on our side and there are many features, starting with several suction powers and water flow rates. During a cleaning, the app allows you to follow the movements of the robot and, if no map has yet been saved, to follow its creation and save it at the end. Multiple maps can be saved as needed for different floors. The Q7 Max+ is very precise in its location and the maps are easy to read and modify.

Parts can be separated and merged if the cutout does not match. Roborock allows you to add a type of floor to adapt the cleaning, as well as furniture from a selection, however, quite basic. In addition, users will be able to create virtual walls, no-go zones and other areas not to be mopped when the mop is installed, at the location of carpets for example. Note also that the vacuum cleaner knows how to recognize carpets and increase its suction power by passing over it.

Once the map is completed, it becomes possible to send the Q7 Max+ to clean a specific area or room. It is also possible to choose the order of the rooms, as well as settings for each in the case of a complete cleaning. The Roborock app also offers to schedule cleanings, but also to define Do Not Disturb slots to prevent, for example, the vacuum cleaner from resuming a cleaning in the middle of the night when it has not had enough battery. to complete its cycle.

Finally, there are controls to drive it manually and various settings for automatic emptying. The set is accompanied by a notification system. A very complete app in short, but also responsive and pleasant to use.

Maintenance

The automatic emptying station that accompanies the Q7 Max+ greatly facilitates its maintenance since it avoids having to empty the robot’s collector manually. It also slows down the clogging of the filter integrated into said collector. After sucking 20 g of cocoa from the robot and sending it to empty at its base, we never found more than 0.2 g in the filter, regardless of the power selected (three are offered). It may still be useful to take a look at it from time to time and rinse it with water, but it is especially worth noting that cocoa was found on the station ramp, around the mouth of the station. aspiration.

It may therefore be necessary to clean it from time to time, in addition to changing the full bag, which should happen more or less every seven weeks according to Roborock. Two are provided, but it will therefore be necessary to acquire others. We would have preferred Roborock to leave the choice of whether or not to use bags, like the Auto-Empty Dock of the S7 and S7 Max V.

To return to the robot, it will also be necessary to clean the mop when it is used, and to ensure that its various sensors remain clean. The brushes can also be cleaned. It’s not uncommon to find hair wrapped around the side brush, a problem we didn’t encounter with the main brush which easily dislodges from its slot. Roborock also recommends changing it every 300 hours of use in the app, which includes many other tips in its Maintenance section.

Navigation system

If it does not offer the most sophisticated navigation system on the market, or even in the Roborock catalog, the Q7 Max + can count on a laser rangefinder and various sensors to move around and avoid the many traps that our homes contain.

During our tests, the Q7 Max+ performed quite well. He always proceeds in the same way, starting by going around the rooms before crisscrossing the interior in a zigzag fashion. He can also cut the pieces into several areas when they are too big, but then keeps the same logic to clean them, without ever getting his brushes tangled when going from one area to another.

The Q7 Max+ is also methodical when it encounters furniture or large obstacles, slowing down to carefully circumnavigate them before resuming its journey. Small obstacles—or at least those below the height of the rangefinder—are at risk of being knocked over if they aren’t heavy enough to trigger the bumper pressure sensors, or swallowed and dragged along. it’s about cables, for example.

It is therefore better to store a minimum before starting a cleaning to prevent the Q7 Max+ from ending up blocked, even if it must be recognized that it only rarely called for help during our tests.

He has also shown himself capable of climbing chair legs and doorsteps without too much difficulty, which does not prevent him from missing some dirt, under the curtains for example. Looking at it along those of our laboratory, we note that it advances in an arc: the area has therefore been poorly cleaned. The Q7 Max + also struggles to fold dirt along the baseboards, and especially in the corners, despite its side brush.

On our navigation test, the new Roborock vacuum cleaner managed to collect 80% of the dirt scattered around our laboratory.

Suction

The Q7 Max+ is among Roborock’s most powerful robot vacuums on paper, and it shows in our suction tests. On hard ground, it managed to pick up 92% of the waste scattered over our test area in normal mode, and 94% with maximum power. These rates rise to 94 and 97% on our fine carpet, and 82 and 80% on our high pile carpet.

It is therefore doing a little less well on this last surface, but remember that it is still the most difficult to clean for robot vacuum cleaners. Only a few models achieve more than 90%, such as the Roomba S9+ and the Rowenta Xplorer-95. The S7 Max V did not do any better on this surface, but was a little more “heavy” on the others. Surprisingly, the S7 had been superior on all surfaces, no doubt thanks to its slower movement speed and less suction performance alone as it took 5-7 mins to criss-cross our test area, compared to less 4 min for the Q7 Max+. For better efficiency, we can ask him to make two or three passes.
