I got mind-blowing when I discovered what these Robot vacuums of Roborock S4 vs S5 could do! With excellent cleaning capabilities, smart mapping/mopping system, and strong suction power that can deal with any low and high pile carpet, our two robotic vacuums deserve to have a spot in your house.
Without costing a great fortune to own a robotic vacuum cleaner, I will show you which machine is more suitable for your house and what you specifically need from a voice controls gadget. Before jumping right into the article, have a look at this comparison table below.

Comparison between Roborock S4 vs S5
Design
Roborock vacuum cleaners often come with a round shape and two-color options of white and black. These affordable gadgets are quite identical in construction but different in features and needs.
For example, the S4 and S5 machines are constructed with a turret-mounted on the lid’s top for deep clean and precise navigation. This turret includes LDAR and vSlam laser technology that create algorithms maps for your floor plans and logical spot cleaning patterns. But instead of only going for vacuuming the house, Roborock S5’s turret is featured to support sweeping, mopping and vacuuming as well.
Their premium quality in construction is no doubt. The Roborock S5 machine uses a bristle 3-arm side brush for a soft touch and gathering dust, while its counterpart adds 2-arm more on the durable rubber brushes, allowing the S4 to hug edges more precisely.
These side brushes are created to support the main anti-tangled single brush. Using the Mi Home app control, you can command the machines’ brush to adjust the speeds. Apart from that, users still can control the device to follow a specific path, set schedule cleans, view the progress and much more.
While they have similar dimensions in width and depth, the Roborock S4 model is 2 inches higher than the advanced S5 gadget. By designing so, the S5 Roborock vacuum cleaner has more ability to slide under the narrow path between floor and furniture.
I’m the one who does not care about weights since I’m living in a flat and there is no need to carry the machine upstairs. But weights are important at some points. While carrying the water tank at the back, the S5 Roborock vacuum cleaner offers somewhere between 7.5-8.3 pounds, varying by the amount of water for mopping.
I believe each of us has different views for each product in terms of aesthetic point of view. For me, I would choose the Roborock S5 for its glossy black finish instead of black matt shade like any ordinary vacuum cleaners. Furthermore, this minimalist design carries so much function and versatilities inside it, making me want to purchase it right away!
Suction Power
A 2000 Pa level of suction can easily wipe away all the debris, particles or stubborn dirt in your house with one go. Even though the motor suction of two Roborock vacuum cleaners have not reached the limit of 2500 Pa like Roomba S9 or Roborock S6 MaxV, it is strong enough to deep clean dirt compartments, pet hair, or food spill.
Say goodbye to all the problems you have encountered with the messy hardwood and filthy low-pile carpet fibres. This strong suction power is given a massive boost when both devices can automatically detect carpets and increase the maximum pressure for deep cleaning modes. This is called the Carpet Boost feature.
When detecting dust and cereal, S4 and S5 robotic vacuum cleaners release a power of 500-1000 Pa. And as for heavier objects such as soybean or steel bars (not recommended to let the vacuum suck steel bars into the machine), the max suction level of 2000 Pa will be activated.
Within the possible scale of 0.8 inches, the high-quality S4 and S5 robotic vacuum cleaner can climb over and pass through obstacles with ease. Keep in mind that this feature is not applicable when the water tank is filled with water.
I’m quite impressed at both devices’ outstanding performance and high suction level compared to their price. Since both of them offer the same engine power, I believe this round will be a tie.
Cleaning Performance
You must be aware that the S5 model comes with 3 different functions for mopping, sweeping and vacuuming. As for the sweeping mode, this versatile machine allows users to wipe along the edge and prevent dust from flying. Its floating main brush system floats up and down, grabbing all tiny particles for up to 2000 sq ft room.
When it comes to mopping, the water tank’s botanical bionic design keeps the water flow steady without leaking. Furthermore, you won’t have to suffer wet floors since the robot itself can wipe its water stain, preventing slippage. Instead of selling tank with water separately like Roborock E4, the S5 machine comes with its own tank at the back.
Unlike this 3-in-1 gadget, the S4 machine with vacuuming mode only is more suitable to pick up debris for large houses of 2700 sq ft. However, it can follow your route planning, stop at the virtual boundaries, or work at specific zoned cleaning.
Great news! The S5 model can do so as well! Just by a flick of a finger, you can command your robot to follow a cleaning cycle, or put extra attention on different types of floor like carpeted floors.
If we dismiss the mopping option and talk only about the vacuuming ability, I have to admit that the S5 robot cleans more efficiently on the tile floors than its competitor. On the flip side, the S4 has more advantage in carpeted floors than S5 due to its 5-arm side brush.
Considering your house’s floor type is crucial in choosing the right robotic vacuum cleaner. If your floor is mainly bare floor, go right for the S5 with mopping and sweeping features. Otherwise, it’s not worth purchasing a 3-in-1 machine when your house does not need it.
Battery Life
A 5200 mAh high-capacity battery is essential for every machine to run continuously for a big room size. Luckily, both of our gadgets are compatible with Lithium-Ion 5200 mAh powerful batteries.
The model S4 can run without stopping for 180 minutes while S5 smart robot vacuum cleaner has 150 minutes after recharging. It’s quite understandable since the S5 is equipped with more features and advanced modes. Battery life will affect a machine’s longevity; therefore, it’s better to choose a model with longer runtimes.
After sweeping, mopping, and cleaning non-stop, the drained battery of S4 will take up about 3,6 hours to fully charge from the charging dock. As for the S5 robotic vacuum, exactly 3 hours is needed for it to self-recharge from 0% to 100%.
My recommendation for you is to go for the longer runtimes machine. Therefore, the winner of this is Roborock S4.
Noise
By introducing noise reduction design, the Xiaowa model of S5 produces noise approximately of 55.5 decibels. Its fitted sealed silencer pads work perfectly for noise reduction, allowing cleaning more quiet and efficient.
The Roborock S4 device is another story. Without any material to block noise, it produces sound at 68 decibels, which is not very applicable to let the machine run at night.
No matter what I think or which aspect I take to decide, the S5 is still more favorable.

Conclusion
As I have stated above, Roborock S4 vs S5 machines are suitable for different needs and purposes. Some would see that mopping and sweeping functions are the inevitable modes for their house while others think only vacuuming function is needed.
Overall, based on my experience, I would like to give S5 vacuum cleaner a try. With such a powerful battery and 2000 Pa engine, it can handle the noise barrier that other machines fail to do so.
