Comparison between Roborock S4 vs S6

Design

This is the third time I write an article comparing Roborock S4’s design to other Roborock gadgets. And as you can see during your search, both models are fairly identical. They all come with an O-shaped construction, that is simple, typical and especially difficult to get the most debris in the wall corners.

Provided by two distinct black and white shades, both modern robot vacuums tip the same scale of approximately 7 pounds. Why approximately? Because the S6 vacuum cleaner is equipped with mopping mode, which allows it to carry a water tank underneath its engine. Therefore, the S6 robotic vacuum cleaner’s weights depend much on water level in the tank. Don’t worry; it’s still in the portable range.

Though both devices are constructed with a turret mounted on top, the S6’s height is still 2 inches shorter than its counterpart.  This turret supports machines for more precise laser navigation and map-making technology, allowing algorithms and logical spot cleaning. And yes, the S6 model’s silver turret uses LDAR navigation for mopping features as well.

If flipping the machine upside down, you can see each of them is provided with a single adaptive brush that reduces hair tangling and a side brush. Forget all the D-shaped construction; this 5-arm side brush will hug your wall edges and corners without leaving any dirt behind. Especially for the S6 gadget, its brush has boosted 250% more in density, making it soft on your floor but hard on dust.

Of course, the LED lights which alarm users activated modes and Mi Home app control are the two factors that are essential for all advanced robot vacuums. Locating on the top of the buttons lid, LED lights warn users when it’s time to return to the charging dock, and time for the dustbin replacement. 

You can also supervise your robot through an app. With a flick of a finger, you’ll be able to change the cleaning path, create virtual walls, set spot cleaning, etc.

Based on all the advantages points above of the S6 Roborock vacuum cleaner, it’s deserved to have a winner title for the design round.

Suction Power

Yes! As expected from the general-purpose all-in-one robots, these two gadgets share the same 2000 Pa level of suction. Their hyper force will dredge up every speck from deep inside low pile carpets as easily as bare floors. No more dust and stubborn dirt stuck in your feet, even deep dirt compartments and pet hair have no chance to hide!

What’s more? While two vacuum cleaners are compatible with 300 RPM rotating laser sensors to detect dirty areas, the Roborock S6’s 15000 RPM fan spinning will suck up and get rid of everything in a minute. 

Of course, we cannot forget the Carpet Boost feature, which automatically increases the suction power when carpets are sensed. By this I mean both machines can climb up to chunky threshold rugs and clean without owners’ help. 

However, the S4 has a very interesting function of drivetrain for reversing. It can move forward and backwards to get out of tight spots while it’s impossible for its competitor. If your house has many small furniture that block vacuum cleaners’ run path, it’s better to go for the S4 gadget.

Based on that point. I will move my winner card to Roborock S4.

Cleaning Performance 

Unlike the 3-in-1 Roborock S5, the S6 vacuum cleaner is used for mopping and vacuuming only. It can grab all the particles and dirt in one go for a 2500 sqft room while its counterpart’s cleaning area is 2700 sqft.

When valuing an iRobot vacuum cleaner, suction level, filters, and battery life are the three main points users should consider. And Roborock knows how to not disappoint users by applying the anti-allergic Hepa filters to its machines. 

These filters capture even the tiniest particles floating in the air and ground, including in-home allergens such as pollen, dust mites or pet danders. Furthermore, it’s quite budget when you can wash these filters after each use. It should last up to several months before the next purchase. 

So, here is the answer to the million-dollar question of whether you should purchase an S6 robot vacuum with mopping modes. Indeed, houses with carpet floors don’t need mopping functions. No one would like to buy an expensive machine with features that their homes aren’t suitable with.

On the flip side, you can give a try at this S6 device if you want to give your house hard floor an extra care and attention. Its mopping modes will do a decent job at cleaning and wiping dirt stain in the grounds. Even this S6 model is doing the mopping job better than any other Roborock models; I still don’t recommend you to purchase it for this function. The reason is…it’s not really worth spending extra money for it.

So my choice for this round is S4 Roborock.

Battery Life

Long story cuts short! Roborock S4 battery life is more efficient.

Built with Lithium-Ion 5200 mAh batteries, Roborock S6 vs S4 take 150 minutes and 180 minutes, respectively, to run non-stop until their next charge. These powerful batteries allow both gadgets to adventure freely around your house and return to the charging dock for fresh energy supply.

The drained battery of S4 will take up about 3,6 hours to fully charge from 0% to 100%, while the S6 vacuum cleaner requires nearly 3 hours.

My recommendation for you is to go for the more extended runtimes machine. Therefore, the winner of this is Roborock S4.

Noise

Many people claim that the Roborock S6 is 50% quieter than the S5 model – a vacuum cleaner that produces noise of up to 55.5 decibels only. However, in my personal experience, I witnessed and heard a much louder noise than just that. 

At least 60-65 decibels are released when the vacuum is going at its maximum speed and suction power. Overall, the harshness typical vacuum noise still exists in S6 robot vacuum. 

The Roborock S4 device is a little bit louder than the S6 model. Without any material to block noise, it produces sound at 68 decibels.

Based on these facts, I will probably turn my card for the S6 device this round.
