The S6 is the latest robot vacuum/mop to come from Roborock. It boasts a lightning-fast processor that, in conjunction with a laser-distance sensor, makes quick, logical decisions and memorizes multiple maps. You can even schedule the S6 to clean by room and draw no-go zones on the app. Plus, the battery lasts up to 3 hours between charges.

While the S6 offers a more precise navigational system than the E35, many of the Roborock E35’s features were carried to the S6, such as the ability to recharge and resume, the presence of reservoir filters and automatic suction boost. However, the E35 vacuum/mop’s bin is bigger, and its brushroll bristles are gentler on hard floors.

Strong Suction

The Roborock S6
Producing 2,000 pascals of suction, heavy debris is no problem for the Roborock S6. Out of all four suction modes, balanced is one of the quietest at 56 decibels. A pressure sensor detects carpet, automatically kicking up the suction while the washable E11 filter inside the top-loading 480-milliliter tank traps 95 percent of micro-particles.

Also included on the robotic vacuum/mop is a webbed side brush that works exceptionally well at grabbing debris from wall edges. Roborock improved upon previous brushrolls by making the S6’s brushroll bristles stiffer to enhance the robot’s carpet-cleaning prowess.

You can count on the Roborock E35 to pick up the most stubborn debris thanks to its 2,000-pascal suction system. Roborock gives you a choice of four suction speeds, including the low-level quiet mode and 62-decibel balanced mode. An auto-boost mode increases suction when the robot is on carpeting.

Inside the E35’s top panel, you’ll find an easy-to-access dirt bin, which can hold 640 milliliters’ worth of debris. The bin itself contains a washable E11 media with a 95-percent filtration rate. The V-shaped brushroll proves capable at lifting dirt from the carpet, but its bristles are gentle enough for hard floors, and there’s also a standard side brush.

Conclusion: While both robotic vacuum/mops generate 2,000 pascals on their highest of four suction modes, the S6’s suction is slightly quieter. Each one also self-increases the suction to handle the demands of carpeting. Although the E35 has a larger dirt bin and a hard-floor-friendly brushroll, the S6 is equipped with a high-tensile brushroll and a webbed side sweeper.

Even Mopping

The Roborock S6
With the Roborock S6, you get reusable and disposable mop pads. These pads attach directly to the plate underneath the reservoir, and one quick rip removes them for washing or tossing. Since the water drips onto the pad, you don’t have to worry about drips or puddles, and two in-tank filters keep the water flowing evenly.

Going from vacuum to mop is incredibly easy. After you put on the mop pad of your choice and fill the 140-milliliter reservoir with water, the reservoir simply slides into the robot’s underside. All you have to do is select the flow rate and press start to make the S6 suction as it mops.

The Roborock E35
A pair of vascular filters provide ingenious water distribution when the Roborock E35 is in mop mode, evenly soaking the reusable pad. The reservoir can hold approximately 150 milliliters of water that is designed to direct-drip onto the pad. Simultaneous suction makes for a spotless finish on any hard-surface floor.

The reservoir slides underneath the E35 without the need to flip over the robot. You even have your choice of multiple flow rates. The lightest flow is suitable for everyday mopping, while the heaviest flow helps tackle stuck-on messes. With a slot and adhesive, the pad won’t come loose when the robot is in motion.

Conclusion: Even though the Roborock E35 holds more water than the S6, the difference in capacity isn’t enough to increase the mopping time. Each reservoir uses vascular filters to distribute the water to prevent leaks. When it comes to the mop pads, the S6 offers disposable as well as reusable ones, both of which are easier to attach/detach.

Intelligent Navigators

The Roborock S6
Roborock integrated plenty of navigation technology into the S6. Among its 14 sensors, there is a laser-distance sensor and cliff-spotting sensors. SLAM technology and adaptive routing allow it to create a map and locate its position on said map while driving in an efficient Z-pattern. Thanks to its 32-bit quad-core processor, the S6 can save up to three maps.

An accelerator, a compass and an odometer also aid the Roborock S6 as it navigates your home. Using Roborock’s Room Management 3.0 technology, the S6 can even detect the room it’s currently cleaning. Robust wheels allow the robot vac/mop to climb 0.8-inch inclines, and a bumper strip keeps the housing intact in the event of an accidental collision.

Inertial navigation positions, orients and measures the velocity of the Roborock E35, using a microprocessor, two six-axis gyroscopes and a pair of motion sensors. Optical sensors and tracking sensors keep the E35 on course, putting it in a logical straight-line path while multiple cliff sensors prevent falls down the stairs.

The E35 is also equipped with electronic compasses to help guide it through your house. Roborock programmed the E35 to slow its speed when it approaches obstacles. A rubber strip provides cushion should the E35 make contact with an object, and heavy-duty wheels can climb thresholds up to 0.8 inches.

Conclusion: A side-by-side comparison of the S6’s and the E35’s navigational systems show that the Roborock S6 is more advanced with its SLAM, Room Management 3.0 and adaptive routing technologies. However, the E35 does well at time-saving, comprehensive floor coverage thanks to the inclusion of inertial navigation, tracking sensors and optical sensors.

Wi-Fi Controls and Extended Battery Power

The Roborock S6
A start/pause button, a dock button and a spot button give you convenient localized control. When walking up to the robot is inconvenient, you have the option of giving it voice commands through Alexa or Assistant or using the Mi Home app. With this smartphone app, you can create on-map cleaning, draw no-go zones and locate the S6.

The 5,200 milliampere-hour lithium-ion battery can last for hours at a time – up to 180 minutes on quiet mode. The E35 not only recharges on the dock without assistance but also continues cleaning once the battery replenishes, allowing it to cover 200-plus square meters per charge. Roborock also added hiding spot for the dock’s cord.

The Roborock E35
Roborock enabled the E35 with a Wi-Fi connection, so you can pair it with Assistant or Alexa and control it via a smartphone. Voice commands include dock, start and stop while the Mi Home app offers locate, manual drive, scheduling and real-time mapping. If you choose, start/pause, spot clean and home can be engaged via the onboard panel.

Powering the Roborock E35 is a 5,200 mAh lithium-ion battery. At full charge, the battery provides a runtime of 150 minutes. In turn, the E35 can vacuum or mop 150 to 200 square meters on a single charge. When the battery is low, the E35 automatically returns the dock. Once it has recharged, the robot finishes cleaning.

Conclusion: Roborock offers control by localized buttons, voice commands and a smartphone app. Although the S6 and the E35 share the same onboard functions and Alexa/Assistant skills, their app capabilities differ with the S6 giving you map customization. They also contain the same battery; however, the S6’s superior navigation system gives the robot a longer runtime.

Efficient and Effective

These two robot mop/vacs also share many of the same great features. Both are equipped with strong variable-speed suction and automatic suction boost. They also distribute water evenly, suctioning as they mop. As with the suction, you have direct control over the water level. Plus, both automatically recharge and resume cleaning.

For those who have thick carpeting and appreciate pristine baseboards, the Roborock S6 has a tough-bristled brushroll and a webbed side brush to handle both surfaces. The battery’s 3-hour runtime makes the S6 ideal for large homes. This robotic vacuum/mop also offers multiple map saving, loads of navigation technology, virtual zone/barrier creation and easily removable mop pads.

People who have tile and other delicate hard floors should consider the Roborock E35 because its brushroll’s bristles are softer. The robot’s 150-minute runtime and extra-large bin service medium to large-sized homes. When you secure the reusable mop pad, it stays put for the duration.
