Roborock Q Revo vs S7: Differences
After weighing the differences between these two robotic vacuums, I concluded that the Roborock Q Revo wins 4:0 against the Roborock S7 thanks to its powerful suction, navigation technique, and more. Please read the breakdown below for the details.
Cleaning Performance
Winner: Roborock Q Revo
Vacuuming
Both the Roborock Q Revo and the Roborock S7 come with a single rubber brush roll and a side brush. In my pick-up tests, these robots can handle all types of debris I used, from the fine consistency of sand to the more sizeable challenge posed by Froot Loops. Both vacuums performed well on hardwood floors and medium-pile carpets, easily picking up even challenging kitty litter on low power mode.
The Roborock S7 brings an interesting twist to the table with its newly designed brush housing. This design enables the brush to move in multiple planes, conforming better to the floor and creating a more secure seal, preventing debris from escaping the cleaning path.
According to the manufacturer, the Roborock Q Revo boasts a suction power of 5500 Pa, which is significantly higher than the S7’s 2500 Pa. As a result, the Q Revo outperforms the S7 in specialized cleaning tests such as crevice cleaning and deep cleaning on carpets. It is better at effortlessly navigating through crevices and extracting more embedded dirt than the S7.
Pet hair performance
Both the Roborock Q Revo and the Roborock S7 have impressive suction capabilities for cleaning pet hair, but deciding which one is superior requires understanding nuanced differences.
Firstly, both robots have robust suction for picking up pet hair but can still experience tangling around brush rolls when dealing with a large amount. The Roborock Q Revo has slightly better suction power than the S7, making it more efficient at capturing pet hair, especially from dense carpets.
Fortunately, both the Q Revo and the S7 come equipped with rubber brush designs that make detangling a breeze, typically requiring just a few seconds of your time.
The Roborock Q Revo has a unique feature: the ability to self-empty, while the S7 doesn’t. This function causes some trouble when dealing with pet hair. The curved design of the chute can sometimes cause clogs, which is a slight drawback. However, with more frequent cleaning cycles and time, the issue seems to have been reduced.
Mopping
The Roborock Q Revo employs a dual mop pad system, which is certainly innovative. During the mopping process, the pads spin and apply pressure in a downward direction. This approach effectively removes dry stains, including tough residues like fruit juice and coffee. However, this robot is somewhat less useful when dealing with wet stains. The mop pads can easily become overloaded, leading to unsightly streaks on the floor.
In contrast, the Roborock S7 comes with a semi-circle mop pad. When operating, the machine will vibrate the mop pad back and forth, making it easier to remove stuck debris. In my opinion, the mop pad design of the S7 absorbs stains better and has a larger surface area in contact with the floor compared to the Revo.
However, to ensure the best mopping results, you will have to manually pre-soak the mop cloth. Just filling the water tank and expecting consistent mopping over extended periods is not viable. The S7’s mopping feature is most effective in small to medium-sized rooms. For larger spaces, human intervention becomes necessary, primarily to re-soak the mop cloth, as the water tank’s passive dripping doesn’t always suffice.
Design & Usability
Winner: Roborock Q Revo
Build quality
The Roborock brand is well-regarded for its dedication to craftsmanship, and both the Roborock Q Revo and the Roborock S7 are reflections of this commitment.
Both robots have a sophisticated design and strong construction, with materials that feel top-notch to the touch. This showcases Roborock’s commitment to both style and durability. The buttons are highly responsive and user-friendly, and the integrated components, such as the dustbin and water tank, fit together seamlessly, decreasing the chances of damage over time.
Dimensions and weight
Both models have a similar weight and dimensions, making them a great option for any home. Based on my experience, they are not the lightest or most compact machines, but they are still passable. They are compact enough to ensure the robots easily glide under most furniture pieces, offering effective cleaning coverage.
Battery and charging
The Roborock Q Revo and Roborock S7 both use high-quality lithium-ion batteries to power their systems. These batteries are renowned for their durability, longevity, and ability to maintain a charge over time, making them a popular choice for many high-end robotic appliances.
Their battery life is impressively long, providing up to 180 minutes of uninterrupted cleaning on a single charge. This extended battery life is very helpful for larger homes or those who prefer to run their robotic vacuums less frequently.
They have a recharge time of around 5 hours. Although it may appear pretty long, considering the 3-hour runtime, it is proportionally appropriate. This feature guarantees that the robots are fully charged overnight or during work hours, ensuring they are ready for another cleaning cycle.
Both of them have the ‘ recharge and resume’ function. This feature allows the robot to return to its charging dock when the battery is low, recharge, and then continue cleaning from where it left off. It is advisable to verify if both of these models come equipped with this useful feature.
Navigation and obstacle avoidance
Both the Roborock Q Revo and the Roborock S7 vacuum cleaners use the latest PreciSense® LiDAR navigation technology to create efficient cleaning routes and ensure thorough coverage. However, the way they detect and avoid obstacles is different, and this affects their performance in real-life scenarios.
The Roborock Q Revo utilizes front-mounted sensors that use structured light to detect obstacles. Structured light sensors emit a known pattern of light onto surfaces, which deforms when it reflects off objects.
By analyzing these deformations, the system can determine the depth and contours of objects in its vicinity. This should result in better obstacle detection and avoidance. However, in practical tests, the Q Revo seems to perform poorly in this regard.
The Roborock S7 takes a more traditional approach to obstacle detection by using a standard infrared sensor at its front. This means the robot doesn’t recognize objects like the Q Revo does.
Control
Winner: Roborock Q Revo
Manual Control
Both Roborock models have buttons on the robot itself that can be used for basic manual controls. These buttons allow you to quickly and easily start or pause a cleaning cycle or send the robot back to its charging dock. Although the app provides a wider range of functionalities, these onboard buttons are helpful when you need to give quick and immediate instructions.
App Connectivity
Drawing virtual barriers directly on the app is one of the most impressive features of both the Roborock Q Revo and the S7. I highly appreciate this convenience, as it eliminates the need for physical barriers or magnetic tapes. The process of digitally setting boundaries is much better.
All it takes is a few taps on the app to demarcate areas that the robot should avoid. This feature is particularly useful for homes with fragile items, pet zones, or certain rooms that require a different cleaning regimen. It’s an invaluable feature that makes cleaning hassle-free and more efficient.
Moreover, both devices can store up to four different maps, allowing users to set varied cleaning schedules for different areas of their homes. This feature is especially useful for multi-story homes or spaces with different types of flooring. You can assign different rooms to specific cleaning days.
Especially the Q Revo has a distinct feature that you can’t find on the S7. It allows you to dictate how often the robot returns to its base station for tasks like washing the pads or emptying the bin. The app also has a feature that enables users to set drying times for the mopping pads, ensuring that the robot performs optimally each time it is put to task.
Cleaning & Maintenance
Winner: Roborock Q Revo
These two robotic vacuums are crafted to be user-friendly in this regard, but they still require routine attention to maintain their prowess.
The Roborock Q Revo boasts a self-cleaning system that proves invaluable in daily upkeep. It comes with a 350-ml removable dustbin on the robot’s body and a 2.7-liter dirtbag inside the docking station. If you frequently use the mopping feature, you will benefit from the device’s ability to wash its own pads and empty its bin, reducing manual interventions.
However, while the self-washing feature is impressive, you can hand wash the mopping pads occasionally for a more thorough clean. As part of routine maintenance, you should check the wheels, sensors, and side brushes for entangled hair or debris to ensure smooth navigation and operation.
On the contrary, the Roborock S7, while not having the self-cleaning feature of the Q Revo, is designed for straightforward maintenance. This robot features a 470-ml dustbin for vacuuming and a 300-ml water tank for mopping. The dustbin is easily accessible and should be emptied and cleaned regularly.
Both models incorporate a washable E11-rated air filtration system. The E11 rating on air filters is a classification based on the European standard EN 1822 for filtration efficiency. It indicates the filter’s ability to capture and retain particles of a specific size. Simply put, an E11-rated air filter can capture at least 95% of particles that are 0.3 microns in size.
In addition, a washable filter is an excellent feature in a vacuum cleaner, as it allows you to clean the filter under running water, let it dry, and then reinstall it in the vacuum. This not only saves you the cost of purchasing replacement filters frequently but also makes the entire cleaning process more convenient and hassle-free.
