Bottom Line: S6 MaxV is with more powerful suction than Roomba S9.
Mopping – Which Mops and Which Don’t?
Unlike Roborock S6 MaxV, Roomba S9 does not mop – at least not without an additional mopping device. The one here with multipurpose cleaning is Roborock S6 MaxV that gently mops your house using its mopping pad and electronically-controlled wetness.
As a result, you can decide how much mopping wetness you want to clean areas in your home. Need to remove that spilled soup stain in the kitchen? Just set the mopping wetness to a maximum and watch the S6 MaxV glide skillfully while you take a break.
Bottom Line: S6 MaxV Mops, Roomba S9 doesn’t.
Self Emptying – Who can automatically empty their dustbin?
Automatic dirt disposal is only featured in Roomba S9 if the Clean Base attachment is installed on the robot’s docking station. In other words, the S9 comes ready with automatic dirt disposal capability.
Roborock S6 MaxV, on the other hand, does not feature this, and you have to empty the dustbin manually once it is full.
Bottom Line: S6 MaxV doesn’t support the auto emptying dust feature. With S9, you can either purchase the attachment separately or go with the S9+ model.
Which Robot maps better? – Roomba S9 VS Roborock S6 MaxV
Smart Mapping with Roomba S9
The Imprint Smart Mapping of the S9 uses a vSLAM camera and iAdapt 3.0 technology to learn the layout of your house and accurately map it.
Coupled with vSLAM technology and advanced sensors that see obstacles, the Roomba efficiently navigates your home without bumping into walls or furniture.
The vSLAM technology helps the S9 to scan and identify the travel path while mapping simultaneously. As a result, a precise map is stored in the iRobot Home App for all scheduling kinds.
Furthermore, Roomba S9’s imprint mapping allows the robot to recognize rooms from the plan and clean them individually.
Stereo Camera mapping with Roborock S6 MaxV
Roborock S6 MaxV, on the other hand, uses a Laser Distancing Sensor (LDS) system that detects the layout of your house.
Roborock S6 MaxV adopts optical technology when mapping your home. Its Stereo Camera system captures images at 30 fps and stitches them together to form an accurate map of your house.
On top of that, the LDS module aids the S6 MaxV to navigate precisely around your home in a planned path. Furthermore, when a toy, sock, or any obstacle falls in its cleaning way, the S6 MaxV will detect it and adopt an alternate route in real-time.
Are multi-floor maps possible (and can be stored)?
It is unspecified how many maps you can store in Roomba S9. Still, the robot will remember a newly mapped layout for future cleaning jobs. With Roborock S6 MaxV, up to four maps can be stored in the Roborock Home App at one time.
Bottom Line: Both the models are smart ones with the best mapping capabilities, but if you want to know which is more advanced, S6 MaxV takes place.
How long can they clean in a single charge?
Roomba S9 will operate for 120 minutes before its battery runs out. In contrast, Roborock S6 MaxV cleans for 200 minutes (Silent Mode) in a single charge.
Both Roomba S9 and Roborock S6 MaxV are smart robotic cleaners that know when their batteries are low. They will automatically redirect themselves to the docking stations and begin charging when a low battery is sensed.
Do recharge and resume available?
Yes, for both robots. When a low battery is detected, the S9 and S6 MaxV will orientate themselves to charge first. Upon completing their charging cycle, the robots will head to the exact spots they had left off to resume cleaning.
Is the Carpet Boost Available?
The Carpet Boost, or Power Boost in Roomba S9, is a useful feature for cleaning carpets in your home. The S9 will ramp up its suction force when Power Boost is activated and cleans your carpets thoroughly.
The same is featured in Roborock S6 MaxV. The Carpet Boost technology allows the robot to automatically switch to its highest suction pressure when a rug is detected. Once the hard floor is seen again, both robots will revert to their nominal suction force.
Bottom Line: Both models work with carpet boost mode.
Anti-collision sensors in the Roomba S9 guide the robot along walls or around furniture. Besides, there is also a cliff sensor that watches out for a staircase when the S9 is working.
Additionally, the Roomba features Dirt Detect sensors that inform the robot of places of cleaning interest. The dirtier spots will be cleaned thoroughly by the Roomba and ensure no messy trail is left behind.
Like the S9, Roborock S6 MaxV features obstacle sensors that aid the robot while negotiating obstructions. Furthermore, the cliff sensors in the S6 MaxV work proficiently to prevent the robot from tumbling down the stairs. Lastly, an array of peripheral sensors like an accelerometer, infrared sensors, and compasses help Roborock S6 MaxV during navigation.
Roborock S6 Max V can climb over 2 cm or fewer obstacles where it is unknown if the same is doable with Roomba S9. For example, crossing doorsills or getting on top of a thick rug is not a problem for the S6 MaxV.
With Roomba S9, it is uncertain if the robot could climb these barriers.
Bottom Line: S6 MaxV is ahead in terms of sensing abilities.
The capable cleaning brushes
PerfectEdge technology with a Corner Brush for Roomba S9
