Short Description
Released in June 2019

The Roborock S6 was released in June 2019. It came to replace the earlier series, Roborock S5. For the record, there are several variants in the Roborock S6 series. We have the S6, S6 Pure, and S6 MaxV. In this review, we are focusing on the base model, the Roborock S6.

Just like the Roborock S6, the S7 is also a 2-in-1 vacuum cleaner that sweeps and mops simultaneously. When it comes to specialty, this vacuum is best suited for homes with bare floors such as tile, laminate, vinyl, marble; you name it. It also handles all types of carpets satisfactorily and cleans all pet messes, from kitty litter to pet hair and paw marks.

Design and Aesthetics When looking for the best robot vacuum, go for one with a low profile design to allow the robot to creep under most low profile household fittings and furniture and pass between tight spaces. It is also important to discern the different models from their appearance. So, how does the Roborock S6 compare to the S7?

As for specialty, the S7 is designed for homes with all types of bare floors and any carpet, be it a low pile carpet, high pile carpet, Flokati, and area rugs. This robot vacuum also handles pet messes satisfactorily.

Vacuuming Performance As mentioned earlier, the Roborock S6 and S7 both offer vacuuming. So, how do the two compare?
2000Pa
Roborock S6 Vacuuming Performance

The Roborock S6, just like its predecessors, uses a 3-stage cleaning system to vacuum dirt on floors and carpets. There are two brushes; a primary brush and a secondary brush. The primary brush is a spiral bristle brush with 250% more bristles compared to the S5.

In addition, the bristles are soft, so you don’t have to worry about it scratching fragile floors. The brush spins at 1350rpm, scrubbing all kinds of dirt, including stuck on grime. The primary brush is assisted by a side brush that sweeps the deep corners and wall edges.

When it comes to suction power, the S6 packs a powerful variable speed motor that spins at an incredible 15000rpm delivering a whopping 2000pa in Max mode. For the record, there are four suction levels: Quiet, Balanced, Turbo, and Max mode.

2500Pa
Roborock S7 Vacuuming Performance

The Roborock S7 changes a few things regarding vacuuming performance. The S7 comes with an upgraded finned all-rubber floating brush with multiple planes of movement for better agitation and dirt pickup.

There is also a single brush for sweeping the wall edges and deep corners. Regarding suction power, Roborock equipped the S7 with a powerful multispeed motor that delivers a whopping 2500pa when in Max mode.

This is what makes it the best for high pile carpets, area rugs, and Flokati. The S7 also has four suction levels: Quiet, Balanced, Turbo, and Max mode.

Mopping Performance The Roborock S6 and S7 are both robot vacuums with mopping functions. In this section, we have detailed all the mopping features of the two robot vacuums.
140Ml water tank
Roborock S6 Mopping Performance

The Roborock S6 comes with a 140Ml water tank that enables the robot vacuum to mop efficiently without dispensing excess water. This is a great feature, especially when mopping hardwood floors.

As you may be aware, hardwood floors are very fragile – excess water will damage them. When it comes to scrubbing stains and grime, the S6 uses a microfiber cloth.

Unlike most robot vacuums with a mop that wet carpets, the S6 has a cool feature called No Mop Zones. As the name suggests, this feature allows homeowners to create limits where the robot shouldn’t mop.

300Ml electric water tank
Roborock S7 Mopping Performance

The Roborock S7 comes with enhanced mopping functions. First, it comes with a larger 300Ml electric water tank that guarantees efficient water usage. It also uses a microfiber cloth for mopping, but then there are a few extras.

First is Roborocks Sonic Technology that scrubs stubborn stains satisfactorily. The mopping head vibrates up to 3,000 times per minute, thus eliminating all kinds of stuck-on dirt, from pet urine stains to muddy footprints.

What’s more? There’s automatic mop lifting that raises the cleaning head when carpets are detected. For the record, the S7 uses Ultrasonic Carpet Detection that is 100% accurate in the detection of carpets. To guarantee that your carpets won’t be mopped, the robot also features No Mop Zones.

Filtration and Bin System Robot vacuums are not just about vacuuming; they also purify the air. When buying a robot vacuum, you should go for a robot vacuum with a filtration system that captures all allergens and other elements that can trigger allergies or cause bad odor. Besides filtration, you should also assess the bin capacity and, importantly, automatic self-emptying. So, how do the two compare?
0.48L bin / E11 air filters
Roborock S6 Filtration

The Roborock S6 comes with washable E11 air filters that capture 95% of allergens.

For the record, these are not true HEPA filters but still, they get the job done, but they are not as perfect as true HEPA filters. When it comes to the bin, the S6 comes with an onboard 0.48L bin.

Unfortunately, the S6 doesn’t empty itself automatically, so you will have to empty it manually, preferably after each cleaning session.

0.48L bin / E11 air filters
Roborock S7 Filtration

Among the differences between Roborock S6 vs. S7 is the filtration and bin system. The S7 comes with the same washable E11 filters, but then, the bin system is different. While the S6 comes with a 0.48L bin, the S7 comes with a 0.47L bin. Perhaps the biggest difference is the inclusion of Roborock’s innovative automatic self-emptying.

With the S7, you can forget the tedious manual bin emptying tasks. But then, note that the S7 doesn’t come with the Roborock Auto-Empty Dock though it is compatible with the technology. However, the Roborock S7+ comes with the Roborock Auto-Empty Dock.

Battery and Runtime The autonomy of a robot vacuum, i.e., the battery and runtime, is also an important consideration. When buying a robot vacuum, always go for one that has a high capacity battery, translating to longer runtime. Besides runtime, check out the power management options. Now, how does the autonomy of the Roborock S6 compare to that of the S7? Let's find out.
5200mAh/180 minutes
Roborock S6 Battery and Runtime

The Roborock S6 comes with a large 5200mAh lithium-ion battery that offers a cool 180 minutes runtime when in Quiet mode. This is enough charge to vacuum an area of up to 300㎡. Of course, when in high power modes, the runtime is shorter.

Now, when it comes to power management, the robot is intelligent enough to recharge and resume cleaning automatically. What’s more? There’s Top Up Charging, a feature that enables the robot to dock and get just enough charge to complete the task at hand instead of waiting for the entire 3 hours recharge time.

5200mAh/180 minutes
Roborock S7 Battery and Runtime

One of the similarities between the Roborock S6 and S7 is the battery and runtime. Here again, the Chinese brand included a 5200mAh lithium-ion battery that offers 180 minutes runtime in Quiet mode.

The S7 will also recharge and resume cleaning automatically. It also comes with the Top Up Charging feature to ensure the job is done on time, even when the battery gets depleted midway.

Navigation and Mapping The navigation and mapping system of a robot vacuum is another crucial factor to consider when buying a robot vacuum. This is because it determines where the robot can reach and, importantly, the efficiency of cleaning. Without further ado, let's get into it.
LDS Navigation
Roborock S6 Mapping

The Roborock S6 comes with an LDS Navigation system that relies on a Sensient sensor array that includes an infra-red cliff sensor, accelerometer, odometer, and compass. These sensors help the robot vacuum to avoid hitting obstacles and falling off the stairs.

When it comes to floor mapping, the robot vacuum uses a powerful 32-bit quad-core processor and LDS Laser Navigation. The duo creates high-precision maps and can even store up to 3 maps.

Other features that this robot vacuum cleaner comes with include Selective Room Cleaning, No-Go Zones, Zone Cleanup, Real-Time Robot Location, Invisible Walls, and No Mop Zones.
