This post will compare the Roborock Q7 vs Q Revo. They offer similar features, such as LiDAR navigation technology, a recharge-and-resume feature, and a plethora of intelligent functionalities once integrated with the Roborock app. The Roborock Q Revo takes the lead with a do-it-all home base and two counter-rotating mopping pads for more efficient mopping. The Roborock Q7, in return, is more affordable.

Roborock Q7 Vs Q Revo: Differences
The Q Revo wins 5-2 against the Q7. Let’s read on to see how the differences between them will affect your choice.
Cleaning Performance
Winner: Roborock Q Revo
Airflow
| Roborock Q7 | Roborock Q Revo | |
|---|---|---|
| Quiet | ≈ 7.6 CFM | ≈ 8.1 CFM |
| Balanced | ≈ 9.6 CFM | ≈ 9.4 CFM |
| Turbo | ≈ 10.1 CFM | ≈ 11.6 CFM |
| Max | ≈ 15.8 CFM | ≈ 13.1 CFM |
The Roborock Q7 has a maximum output of 15.8 CFM compared to the Q Revo, which maxes out at 13.1 CFM. Surprisingly, this advantage didn’t do much in the cleaning experiments (more below) because the Q7 indeed got better scores.
Hard Floor
| Roborock Q7 | Roborock Q Revo |
|---|---|
| ≈ 97% | ≈ 99% |
The Roborock Q7 got a slightly higher score on my hard floor, picking up almost all the debris, even though it has lower airflow and shares the same rubber bush roller as the Q7, and I was just unsure why.
Carpet
| Roborock Q7 | Roborock Q Revo | |
|---|---|---|
| Low-pile Carpet | ≈ 94% | ≈ 94% |
| High-pile Carpet | ≈ 95% | ≈ 90% |
These Roborocks performed equally on my low-pile carpet, collecting up to 94% of total debris. The Q7 was better on the high-pile one, picking nearly five percentage points higher.
Hair
| Roborock Q7 | Roborock Q Revo | |
|---|---|---|
| 5-inch Strands | ≈ 87% | ≈ 62% |
| 10-inch Strands | ≈ 61% | ≈ 55% |
As you can see, the Q7 was the better robot for cleaning hair. And as always, a lot of strands were wrapped in their brush rolls, but it was very easy to dislodge tangles since the hair didn’t wind too tightly.
Design & Usability
Winner: Tie
First Look & Dimensions
| Roborock Q7 | Roborock Q Revo | |
|---|---|---|
| Dimensions (W x H) | 13.8 x 3.8 inches | 13.9 x 3.8 inches |
| Weight | 8.38 lbs | 10 lbs |
Similar to other Roborocks, the Q Revo and Q7 are short, circular bots, just like super big hockey pucks, with similar dimensions and the same LIDAR tower for mapping. They are hybrid robots, but their mopping systems vary, which I’ll discuss later.
Extractor & Side Brush
The next similarity is the main brush roller used: The Q7 and Q Revo share Roborock’s new-generation rubber roller with a spiral design that is removable for easy untangling any hairs or debris caught in it.
The Q Revo is fitted with a three-prong, bristled-tip corner brush, compared to the S7 MaxV Ultra with a five-arm, all-rubber version. I didn’t see any variance with cleaning performance, as both rotated slowly to prevent dust dispersion, but the rubber version surely offers better durability and, of course, is easier to clean.
Navigation
One of the strongest points for the Q Revo and Q7 is how quickly and accurately they draw the maps, thanks to the extraordinary ability of a LiDAR sensor on top. They can indeed quickly find a way around, mapping more accurately and faster than their vSLAM-based counterparts, even if they don’t get adequate light.
What’s more, they can remember multiple floors, or rather, up to four distinct maps. Drop them in a new region or floor, and they will automatically choose the appropriate map or create a new one, provided their memory isn’t already brimming with four maps. They are generally well-suited for most households, considering it’s uncommon to encounter apartments that stretch beyond four levels.
The Roborock Q7 has no front-facing camera or any cutting-edge technology to avoid obstacles. Instead, it is equipped with bumpers to prevent damage when colliding with walls or obstacles. So the only issue is that this one chews up electrical cords or, more dreadfully, passes over pet feces and spreads them around. On the other hand, the Roborock Q Revo is equipped with “Reactive” technology to avoid obstacles. I saw that it only works with sufficiently large obstacles and can’t detect stretched cords.
Battery Life
| Roborock Q7 | Roborock Q Revo | |
|---|---|---|
| Battery Life | ≈ 91-183 mins | ≈ 98–201 mins |
| Charging Time | ≈ 198 mins | ≈ 210 mins |
Both the Q7 and Q Revo were incredibly good in my battery life tests. Both boast a 5,200mAh lithium battery, which is quoted as lasting up to 180 minutes, and my tests showed that they lasted even longer at the lowest power setting. Up the power and adding in mopping will reduce battery life, of course.
They are generally capable of handling large homes without recharging often. Even better, they are designed to smartly return to the charging dock to recharge when needed and return to continue the journey afterward without skipping a beat.
Control
Winner: Tie
Manual Control
Regarding manual control, I mean controlling these bots without needing your phone. Both the Q Revo and Q7 have a Power button to start/end a cleaning trip and a Home button for sending the bot home.
App Connectivity
Both the Q Revo and Q7 can be linked to your phone via the Roborock app and share a set of smart features, from creating 2D or 3D maps and offering a live map to allowing for setting no-go zones, invisible walls, no-mop zones, or spot-cleaning zones. You can also divide and merge rooms as desired and clean some rooms instead of the whole floor. Plus, you can voice-command your bot into action with Google Assistant or Alexa and watch it spring to life.
Via the app, you can also choose the suction power (and water density for the Q Revo) and check out the previous cleaning cycles. You can also monitor the health and wear of crucial components such as the filter, main brush roll, and side roller, all displayed in a handy percentage format.
Cleaning & Maintenance
Winner: Roborock Q Revo
When it comes to capacity, the Q7 features a 0.48-liter dustbin and a 0.35-liter water tank, versus a 0.35-liter dustbin and a 0.8-liter water container on the Q Revo. So the Q Revo seems to need to be emptied or filled more often, as a matter of necessity, but that’s when its all-in-one home base comes into play. This massive tower is designed to care for the robot, including self-emptying the dust bin, self-refilling the water tank, and self-washing and -drying the mop pads.
There are a lot of things a single base can do itself, don’t you think? It uses a 2.7-liter dust bag and a pair of larger water tanks, a 5-liter one for clean water and a 4.2-liter one for storing dirty water after each cleaning cycle. You will still need to manually empty and refill these, but it’s a task that’s infrequent. Additionally, you also need to wash their E11 filters at least once a month.
The Q Revo’s base station is a welcome addition, but like all innovative features, there’s always room for improvement. It only uses warm air (about 45°C, according to the manufacturer) to dry the mop pads, so it took several hours for the pads to dry completely, blurring the line between the effectiveness of the base station’s drying capabilities and natural air drying. So it would be better if the base used really hot air for this task.
Other Features
Winner: Roborock Q Revo
Noise
| Roborock Q7 | Roborock Q Revo | |
|---|---|---|
| Working | ≈ 59-75 dB | ≈ 45-67 dB |
| Self-Emptying | None | ≈ 75 dB |
The Q Revo operates quite quietly, allowing you to watch TV, work, or have a conversation in the same room without being interrupted. On the flip side, the Q7, especially at its peak performance setting, can be a bit loud, similar to the brief yet loud sound the Q Revo emits during its bin-emptying process at the base station – so you may want to watch TV at a higher volume.
Mopping Ability
Speaking of mopping, the Q Revo uses two mopping discs that rotate in opposite directions from each other at 200 RPM, creating a dynamic agitating effect that quickly dispatches even the most stubborn stains. On the flip side, the Roborock Q7 features a half-circular mopping plate that lacks agitating functionality, making it less effective in comparison to the mighty Q Revo.
In my mopping tests, I tested them on both dried-on and wet stains. Both did an excellent job of removing grape juice stains, and that’s what almost all robot vacuum mops I’ve tested could do. For the dried-on BBQ sauce, the Q Revo was better but still not really effective. With wet stains, they seemed less useful since they tended to leave behind streaks, which is a common foible among robot vacuum mops.
What’s more, both have an auto mop pad lifting system, which is becoming a standard for high-end hybrid robots. The Q Revo can lift its pads 7 millimeters, while the Q7 can only raise 5 millimeters. This is a significant advancement, as you no longer have to remove the mop pads when you want to vacuum carpets. And if you have a mix of hard floors and carpeted surfaces in your home, you can vacuum and mop your entire space in a single run.
