convenience of use
The Q7 Max+ looks similar to many other models in the Roborock catalog, excluding the E-series – the latter models do not have a laser rangefinder. We found one in this model. Slightly advanced with respect to the center of the casing, on which it rises almost 2 cm (the total height of the robot reaches 9.6 cm), this rangefinder allows mapping the different rooms of the house and works with several sensors present in the lathe and the bottom of the robot so that it moves without (too) problems.
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 located on the front to not only detect, but also identify certain obstacles. A function that is also found in the roombaj7+ and the JetBot AI.
In addition to the rangefinder, there are some buttons on the top of the Q7 Max+ 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 kind of handle allows the rear part of the hull to be lifted to access the collector, here combined with the water tank intended for the washing function.
Roborock indicates that the union of the two elements has allowed it to significantly increase its capacity, which seems especially true in the case of the water tank. This can hold 350ml, compared to 300ml on the S7. The bin has a capacity of 470 ml compared to 400 ml in the S7 Max V Ultra, but the one in the S7 is identical.
In both cases, it’s relatively comfortable, especially since the Q7 Max+’s automatic emptying saves you from having to deal with the dust bin. Roborock’s second argument also fails for this reason, because it is about having a single item to transport to empty and fill. We can certainly hear it for the Q7 Max without a suction base, but we would have preferred a hatch system to prevent debris from escaping into the dust bin when handled carelessly.
At the bottom of the Q7 Max+, two brushes stand out. The main one, in the center, is a rubber roller that rotates to push the dirt towards the suction mouth. A small rubber brush is also added, but in the shape of a star that turns to the side to bend the debris towards the center. A mop can be added to the rear, but its mount doesn’t vibrate like the S7 and S7 Max V. It only mops the floor at robot speed and so you shouldn’t expect a miracle on tough stains, though the manufacturer proposes a constant pressure of 300 g on the ground.
The Q7 Max+ comes with a charging station, but its also works to empty the manifold. To do this, it includes a ramp through which waste and dirt are sucked up to 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 contain enough dirt that it needs to be changed once every seven weeks.
As a result, this station is much larger than a simple charging station. Its more than 40 cm height will, in particular, prevent the vacuum cleaner from being hidden under furniture when not in use.
Connectivity and application
The Q7 Max+ connects via Wi-Fi via the Roborock app, which then allows you to control it remotely. The pairing went smoothly on our end and there are plenty of features, starting with various suction powers and water flow rates. During a cleanup, the app allows you to follow the robot’s movements and, if no map has been saved yet, follow your 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.
The parts can be separated and merged if the trim does not match. Roborock allows you to add a type of floor to adapt the cleaning, as well as furniture from a selection, albeit quite basic. In addition, users will be able to create virtual walls, no-go zones and other areas that should not be mopped when the mop is installed, for example at the location of carpets. Also note that the vacuum cleaner knows how to recognize carpets and increase its suction power when passing over them.
Once the map is complete, it is 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 the configuration of each one in the case of a complete cleaning. The Roborock app also offers to schedule cleanings, but also to define Do Not Disturb time slots to avoid, for example, the vacuum cleaner 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 control 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.
The automatic emptying station that accompanies the Q7 Max+ greatly facilitates its maintenance since it avoids having to empty the dustpan of the robot manually. It also stops the clogging of the filter integrated in said collector. After sucking 20g of cocoa out of the robot and sending it to empty through its base, we never found more than 0.2g in the filter, regardless of the power selected (three are offered). It can 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 ramp of the station, around the suction mouth.
Therefore, it may need to be cleaned from time to time, in addition to changing the full bag, which should happen every seven weeks or so according to Roborock. Two are provided, but others will therefore need to be purchased. We would have preferred Roborock to leave the option to use or not use bags, like the Auto-Empty Dock on the S7 and S7 Max V.
To get back to the robot, you will also need to clean the mop when in use and make sure its various sensors stay clean. The brushes can also be cleaned. It’s not uncommon to find hair tangled around the side brush, a problem we didn’t find with the main brush easily slipping out of its slot. Roborock also recommends changing it every 300 hours of use in the app, which includes many other tips in its Maintenance section.
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 and dodge the many traps in our homes.
During our tests, the Q7 Max+ performed quite well. He always proceeds in the same way, beginning by going through the rooms before zigzagging through the interior. You can also cut the pieces in several areas when they are too big, but then you keep the same logic to clean them, without ever getting your brushes tangled when moving from one area to another.
The Q7 Max+ is also methodical when encountering large furniture or obstacles, slowing down to carefully circumnavigate them before resuming its journey. Small obstacles, or at least ones below rangefinder height, on the other hand, are at risk of being knocked over if they aren’t heavy enough to trigger the bumper pressure sensors, or get swallowed and dragged along. .It’s about cables, for example. .
So it’s best to store a minimum before starting a clean to prevent the Q7 Max+ from ending up bricked, though admittedly it rarely asked for help during our tests.
It has also been shown to be able to climb chair legs and door steps without too much difficulty, which does not prevent it from missing some dirt, for example under the curtains. Looking at him along those in our laboratory, we notice that he advances in an arc: therefore, the area has been poorly cleaned. The Q7 Max+ also has trouble removing dirt along the baseboards, and especially in the corners, despite its side brush.
In our navigation test, the new Roborock vacuum cleaner managed to pick up 80% of the dirt scattered around our lab.
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 debris scattered around our test area in normal mode and 94% at full power. These rates rise to 94 and 97% in our fine carpet, and 82 and 80% in our deep pile carpet.
So you’re doing a little less well on this last surface, but remember that it’s still the hardest for robot vacuums to clean. Only a few models exceed 90%, such as the Roomba S9+ and the Rowenta Xplorer-95. The S7 Max V fared no better on this surface, but was a bit “heavier” on the others. Surprisingly, the S7 had been superior on all surfaces, no doubt thanks to its slower movement speed and less suction performance, as it took 5-7 minutes to traverse our test area, compared to less than 4 minutes for the Q7 Max+. For greater efficiency we can ask you to make two or three passes.
