The Roborock Q Revo vs S7 Max both sport a clean base that automatically emptys their dustbins and refills their water tanks, and they are equipped with a mop-lifting mechanism. They can also detect and clear obstacles, but they aren’t very adept at evading thin cables and pet droppings.
The Roborock S7 Max has better overall cleaning performance despite its lower airflow. With a vibrating mop that effectively removes stubborn stains, it easily ranks among the hybrid robots with the best mopping capabilities.
Despite its lower price tag, the Roborock Q Revo has higher airflow than the S7 Max and its more expensive siblings, resulting in remarkable cleaning performance. Its spinning discs are also still good enough to clean common household stains.

Cleaning Performance
Winner: Roborock S7 Max
Airflow
| Roborock Q Revo | Roborock S7 Max | |
|---|---|---|
| Quiet | 8.1 CFM | 9.42 CFM |
| Balanced | 9.43 CFM | 11.1 CFM |
| Turbo | 11.6 CFM | 14.82 CFM |
| Max | 13.1 CFM | 17.46 CFM |
As you can see, the Q Revo maxes out at 17.46 CFM, while the S7 Max has a maximum airflow of 11 CFM. However, this advantage didn’t help the first one pick up more debris on my carpets.
Hard Floor
| Roborock Q Revo | Roborock S7 Max |
|---|---|
| ≈ 99% | ≈ 96% |
The Q Revo picked up up to 99% of the total debris on this surface, leaving behind a nearly spotless test lane. Meanwhile, the S7 Max was also very close, with a super high percentage of 98%.
Carpet
| Roborock Q Revo | Roborock S7 Max | |
|---|---|---|
| Low-pile Carpet | ≈ 94% | ≈ 98% |
| High-pile Carpet | ≈ 90% | ≈ 94% |
When tasked with cleaning my low- and high-pile carpets, both devices shone brightly, thanks to their superior airflows. What’s surprising here is that the S7 Max was ahead of the game, even when it boasted a lower peak airflow than the Q Revo.
Hair
| Roborock Q Revo | Roborock S7 Max | |
|---|---|---|
| 5-inch Strands | ≈ 62% | ≈ 71% |
| 10-inch Strands | ≈ 55% | ≈ 64% |
The S7 Max once again had better results, picking up more hair. The point is that although there was a considerable amount of hair wrapped on their rubber roller, detangling them was a piece of cake.
Design & Usability
Winner: Tie
Dimensions & Weight
| Roborock Q Revo | Roborock S7 Max | |
|---|---|---|
| Dimensions (W x H) | 13.9 x 3.8 inches | 13.9 x 3.8 inches |
| Weight | 10 lbs | 10.36 lbs |
Both the Q Revo and the S7 MaxV are circular robot vacuums with a LiDAR tower commonly found in all Roborocks. This design gives them an edge over D-shaped vacuums like the Roomba S9 in navigating tight spaces, but the increased overall height due to the laser-scanning tower poses a challenge when accessing low-clearance furniture.
Extractor & Side Brush
The next similarity between them is the brush roll design. Both of these Roborocks use a single newer bristle-free roller, which is intended to prevent hair tangles better. My real-world tests showed that this roller wasn’t as perfect as rumored, but at least untangling it was easier than a bristle brush bar. They both also have an older 3-pronged bristled side brush, and you can upgrade to an all-rubber corner brush if desired.
Navigation
As mentioned above, both of these Roborocks boast a LiDAR tower that uses laser beams to continuously scan 360 degrees when mapping. This turret increases the overall height of these bots, but it has a leg up in terms of speed and accuracy.
Whereas the majority of vSLAM robots might need 4 to 5 initial runs, if not more, to thoroughly map out your living space, these laser-based bots can nail it in just one or two cycles. Not to mention, they can operate effectively without adequate lighting. Once they remember the map, they will clean the floor in strategic straight lines for thorough cleaning. What’s more, they can save up to four maps.
As for the obstacle-evading ability, they did a good job of avoiding all the big obstacles scattered on my floor, including a shoe, a mug, and a bowl, but they had a hiccup with power cords. Moreover, they got close enough to (fake) pet waste that part of their side brushes touched it. Hence, I wouldn’t recommend them to pet parents.
Roborock rolled out the S7 Max Ultra in 2023, which bears a striking resemblance in name to the S7 MaxV Ultra – minus the letter “V.” Even though it’s considered an upgrade, it’s puzzling that the S7 Max bypasses the RGB camera system and the CCTV function, which is quite useful, at least for me. Perhaps Roborock was trying to please those cautious about privacy? I just don’t know!
Battery Life
| Roborock Q Revo | Roborock S7 Max | |
|---|---|---|
| Battery Life | ≈ 98–201 mins | ≈ 94–186 mins |
| Charging Time | ≈ 210 mins | ≈ 179 mins |
Both are equipped with a large lithium-ion battery with a capacity of 5200 mAh, granting them an impressive span of battery life before needing a recharge. Let’s say your houses are so huge that a single full charge isn’t enough – that’s not a big deal. They will return to the charging station when the battery is low and then resume the business from where they left off once recharged, thanks to the Recharge & Resume function.
Control
Winner: Roborock S7 Max
Manual Control
Without the Roborock app, you only have the option of starting a cleaning trip or sending these bots to their home bases when they are in the middle of a cycle. The S7 Max has a clear spot button, enabling this one to clean a small zone around where you put it on the floor rather than doing a full cleaning cycle.
App Connectivity
To unlock all the smart characteristics of these bots, you need to connect them to your phone via the app. Right on your phone, you can divide rooms and assign them names from an existing list or use your own. Then you just want your robot to clean up the kitchen? You can manage the robot to do this via the app or using your voice if you are using Google Assistant or Amazon Alexa.
The Roborock app can also present the maps these robots have drawn in 3D, and you have the option to add furniture – It’s a nice-to-have feature but not really a useful one. What’s really useful is the live map feature, which allows you to know the location of the robot at all times.
Of course, you can schedule cleaning and set containment areas, including no-go and no-mop zones. You can also use invisible walls instead of no-go boxes to block diagonal areas. In addition to checking information related to previous cleaning cycles, you can inspect the condition of the filter and other parts.
Cleaning & Maintenance
Winner: Roborock Q Revo
As of now, the S7 Max isn’t sold separately like its siblings. Instead, it comes with an all-in-one base in a larger package called the S7 Max Ultra, just like the Roborock Q Revo. That means the small capacity of their dust boxes is not much of an issue.
When they detect that their dustbins are full or after a cleaning cycle is completed, they will autonomously navigate back to the self-cleaning base. Upon docking, the base will initiate a suction process that pulls the debris from the bin into a 2.5-liter dust bag within the base itself. What’s more, the water tank is automatically filled, and the mop pad is also automatically washed and dried – no human touch at all! The app will also notify you when the dust bag needs to be replaced.
Both use an E11 filter, which is washable and can be reused many times – something Mother Nature will appreciate. The app will also remind you when it needs to be replaced.
Other Features
Winner: Tie
Noise
| Roborock Q Revo | Roborock S7 Max | |
|---|---|---|
| Working | ≈ 45-67 dB | ≈ 49-62 dB |
| Self-Emptying | ≈ 75 dB | ≈ 78 dB |
On its lower settings, the S7 Max tends to be louder, yet surprisingly, it turns quieter on the max setting. While these devices typically amp up the noise at their highest settings, you’d only really need that for deep cleaning carpets. Self-emptying their dust boxes is also a noisy process, but it’s over in a flash.
Mopping Ability
These little housekeepers can vacuum first and immediately mop afterward. In the realm of hybrid robots, most just come with decent mopping units, and some others are really great. Happily, the Q Revo and S7 Max fall into the latter category for two reasons.
First off, both come with a liftable mop system called VibraRise technology. This refers to the fact that when these bots detect carpets, they will automatically raise their mop pads. It’s a promising feature, but not bulletproof since high-pile carpets are still prone to getting damped as the Q Revo only raises its mop plate 7 mm off the ground, whereas the S7 MaxV manages a 5 mm lift. So you will still need to set no-mop zones via the app for peace of mind.
Additionally, while most hybrid robots just drag a wet pad across the floor surface, these machines have agitating components to tackle tougher stains. The Q Revo introduces a pair of circular mop pads spinning in contrasting directions, whereas the S7 Max boasts a vibrating mop system – part of VibraRise technology. From red wine to coke splatters, they cleaned up with ease, although dried BBQ sauce proved a bit more challenging.
