In today’s post, I will compare the Roborock Q Revo vs Q7 Max, which have similar functionality but varying levels of automation. Both have LiDAR navigation technology, the ability to save up to four maps and offer the same set of features via the Roborock app.
But when comparing the two, the Roborock Q Revo emerges as the superior choice. Not only does it come with a self-emptying base and an adjustable mopping system, but it also boasts ReActive technology, giving it the edge in detecting and sidestepping obstacles, a feature the Roborock Q7 Max lacks.

Roborock Q Revo Vs Q7 Max: Differences
The Q Revo wins 3-2 against the Q7 Max, and here is a side-by-side comparison between these two Roborocks.
Cleaning Performance
Winner: Roborock Q7 Max
Airflow
| Roborock Q Revo | Roborock Q7 Max | |
|---|---|---|
| Quiet | 8.1 CFM | 7.6 CFM |
| Balanced | 9.4 CFM | 9.6 CFM |
| Turbo | 11.6 CFM | 10.1 CFM |
| Max | 13.1 CFM | 15.8 CFM |
The Q7 Max has higher airflow in the max setting. This one maxed out at 15.8 CFM compared to the Q Revo, with its maximum airflow of 13.1 CFM. But surprisingly, the latter got a higher debris pick-up rate on my hardwood floor (more below).
Hard Floor
| Roborock Q Revo | Roborock Q7 Max |
|---|---|
| ≈ 99% | ≈ 97% |
The Q Revo proved itself to be better on my hardwood floor, with up to 99% of total debris being picked up easily, while the Q7 Max scored an average of 97%. As you can see, the variance is slight, but it proves that higher airflow doesn’t always translate into better cleaning results.
Carpet
| Roborock Q Revo | Roborock Q7 Max | |
|---|---|---|
| Low-pile Carpet | ≈ 94% | ≈ 94% |
| High-pile Carpet | ≈ 90% | ≈ 95% |
On the low-pile carpet, these Roborocks were neck and neck in performance. When the terrain shifted to my high-pile carpet, the Q7 Max slightly outperformed the Q Revo. Again, the difference isn’t significant, like in my hard floor experiments.
Hair
| Roborock Q Revo | Roborock Q7 Max | |
|---|---|---|
| 5-inch Strands | ≈ 62% | ≈ 87% |
| 10-inch Strands | ≈ 55% | ≈ 61% |
I also compared how each Roborock performed during the hair collection experiment, and the results weren’t too close here. The Q7 Max picked up much more hair, both 5- and 10-inch strands, than the Q Revo. Regarding the resistance to tangled hair, they were on par: There was a moderate amount of hair wrapped on their brush rolls, and untangling them was effortlessly simple thanks to the bristle-zero design.
Design & Usability
Winner: Roborock Q Revo
Dimensions & Weight
| Roborock Q Revo | Roborock Q7 Max | |
|---|---|---|
| Dimensions (W x H) | 13.9 x 3.8 inches | 13.8 x 3.8 inches |
| Weight | 10 lbs | 8.38 lbs |
Both the Q Revo and Q7 Max utilize a round-shaped body and a dome contraption on top that houses the built-in LIDAR sensor, similar to other Roborock robovacs. They’re quite alike in terms of size, but the Q Revo is a bit heavier, perhaps due to some additional functionalities.
These bots certainly won’t take up much space when not in use, but the point is that the Q Revo comes with a multifunctional Hulk-sized tower, which I will shed more light on later. It’s narrower but taller than what comes with Roboroc’s flagship lineup, so finding a suitable place to put it might require some thought. The good news is that it looks very nice and can become a showstopper in any part of your living area. The Q7 Max does not come with such a base, but the Q7 Max Plus does.
Extractor & Side Brush
The Q Revo and Q7 Max use the same upgraded bristle-free brush roller, and that’s a good thing. Traditional brush rollers with bristles tend to collect and wrap hair around them, and over time, this can lead to a thick wrapping of hair that needs to be manually removed. With bristle-free or anti-tangle designs, these rollers significantly reduce this accumulation, leading to less frequent maintenance.
The Q Revo features a 3-pronged corner brush with bristled tips, in the exact location of a 5-pronged corner brush on the Q7 Max made entirely of rubber. No doubt, the Q7’s rubber side brush has an edge in terms of durability, and you should know that it is also compatible with the Q Revo, but you need to buy one separately. Bristles may wear out, bend, or even break over time, especially when constantly in contact with hard surfaces, while rubber can withstand more wear and tear.
Navigation
Both of these Roborocks, as previously hinted, use LiDAR technology, which relies on laser beams to measure distances and generate detailed and accurate maps of your entire house quickly and with high precision, even if they don’t get adequate light. They can also store up to four maps in memory for cleaning multiple floors. This means you can manually place the robot on a different floor, and it will recognize and create a new map or use the appropriate map for that level.
Both run in a snake-like pattern for comprehensive cleaning, but the Q Revo gets an edge regarding object recognition and avoidance. The Q Revo is equipped with obstacle avoidance technology to detect obstacles even before making physical contact, which Roborock calls Reactive technology, which is actually an infrared (IR) sensor. I put it through my tests, and it excelled at evading large obstacles like simulated pet waste, a shoe, and a toy doll, just like a real human. But a power cable remained its Achilles’ heel.
As for the Q7 Max, the front-facing sensor allowed it to slow down as it neared an obstacle, while its built-in bumper prevented damage to both the robot and the encountered object. It then found the most optimal route to drive around the object. This is not a problem for normal objects, but a word of caution for those with pets who aren’t potty trained!
Battery Life
| Roborock Q Revo | Roborock Q7 Max | |
|---|---|---|
| Battery Life | ≈ 98–201 mins | ≈ 91-183 mins |
| Charging Time | ≈ 210 mins | ≈ 198 mins |
The Q Revo and Q7 Max are both equipped with a 5,200mAh lithium battery and a “recharge and return” function. The largest-of-the-line battery grants these robots the endurance to operate continuously for up to 3 hours, provided they are set to the lowest power setting.
But it doesn’t stop there. These high-independence robots will go to the charging base on their own in case the remaining battery capacity isn’t enough to complete the entire cleaning trip. Once they have recharged enough, they will resume the cleaning process from where they left off, ensuring they will always complete the programmed cycle and preventing you from keeping a constant eye on the battery status or manually returning your robot to its charger.
Control
Winner: Roborock Q7 Max
Manual Control
While the Roborock app offers a plethora of handy features, making it a go-to for controlling these robot vacuums, sometimes simplicity wins. If you just want something, like starting a full cleaning cycle or sending these bots home for recharging, you can just press the power button or home button on top of them rather than pulling out your smartphone. The Q7 Max also has a spot clean button to clean up a spill in your kitchen, for example, instead of forcing the robot to complete a full cleaning round.
App Connectivity
Since both the Q Revo and Q7 Max work with the Roborock Home app, they have the same set of smart features. In addition to saving up to four maps, the app can show them in 3D form and allow you to add furniture to make them resemble your real-world living space. I just considered the 3D mapping function on this app a sub-feature since it’s useless, at least for me. What I found more useful is the live map feature, which shows the robot’s location in real time and marks the zones it has vacuumed.
After dividing the map into different rooms and labeling them with available names or your custom ones, you can choose to clean by room or set “Cleaning” zones so the robot just cleans small areas within a room. You can also set no-go zones, invisible walls, and no-mop zones to block the robot from entering some unwanted areas.
With voice-controlled systems such as Alexa or Google Assistant at your disposal, you can effortlessly direct the Q Revo or Q7 Max using just your voice. You can also use the scheduling tab for a hands-off approach – this lets you pinpoint the days, designated cleaning zones, and the specific cleaning mode the robot should follow.
Cleaning & Maintenance
Winner: Roborock Q Revo
The Q7 Max features a 0.47-liter dustbin that needs to be emptied manually, whereas the Q Revo has a 0.35-liter dustbin that is emptied automatically when this one is parked at the base. Yes, self-emptying the bin is one of the things the multifunctional base of the Q Revo can do, sending all the contents from the bin to a 2.7L bag. With regular usage, this bag typically requires replacement approximately every seven weeks.
The Q Revo’s do-it-all houses two large water tanks: a 5-liter tank for clean water to refill the water container on the Q Revo and a 4.2-liter to collect dirty water after washing the mopping pads. Additionally, the station employs 45 °C of warm air to dry the mops over several hours, ensuring bacteria and unpleasant odors are kept at bay.
Of course, this all-in-one base doesn’t do everything for you. You will need to open the lid, take the dirty water tank out, dispose of the murky water, and cleanse any sludge settled at the bottom of the tank to avoid any unpleasant smells. You will also need to wash its E11-rated filter under the tap either weekly or monthly, depending on use.
Other Features
Winner: Roborock Q Revo
Noise
| Roborock Q Revo | Roborock Q7 Max | |
|---|---|---|
| Working | ≈ 45-67 dB | ≈ 49-62 dB |
| Self-Emptying | ≈ 75 dB | None |
Both the Q Revo and Q7 Max run silently in their first trio of settings. And while they are somewhat loud in maximum settings, they still maintain acceptable noise levels that won’t disrupt surrounding conversations. What’s really noisy is the automatic emptying process at the Q Revo’s home base, almost as if it’s gearing up for liftoff!
Mopping Ability
The Q Revo and Q7 Max are two hybrid Roborocks, and without beating around the bush, there are two reasons that the Q Revo is superior in moping ability.
For the first one, while the Q7 Max just drags a semicircular mopping plate on the floor without any agitating element, the Q Revo features two spinning round-shaped discs that rotate at 180 RPM for agitating stubborn stains. My hands-on tests revealed that both handled juice stains well, but the Q Revo had a noticeable edge when it came to addressing dried BBQ sauce, though it didn’t perform flawlessly.
What’s more, the Q Revo has a lift-mopping system, so if the robot can detect carpeted areas, it will lift the mop pads up to 5mm and traverse over these areas without wetting them. This would be particularly useful for homes with a mix of hard floors and carpets. Still, this 5mm raise may not work for some high-pile carpets, so designating no-mop zones around such carpeted areas remains a prudent move.
