So, what has the S8 brought to the table?
Navigation
The S8 series uses Lidar to create a map and navigate around. Additionally, each modification has a front camera to recognize objects. Each saves up to 4 maps and is suitable for multi-level houses.
Cleaning performance
The mopping system vibrates, pressing the pad to the floor so it performs better with sticky stains. The S8 and S8+ have the standard vibrating mopping system, while the S8 Pro Ultra has a wider vibrating area to cover more at once. It lifts the mopping pad when it detects carpet for up to 15 mm so it can vacuum the carpet without damaging it.
The double roller brush system ensures better pickup and deeper carpet cleaning, and the S8 series is the first and only in the lineup with two rollers.
The app
The app allows setting the robot to clean a particular room, a specific area, or not to go to one. There are a lot of customizable settings for different types of cleaning.
S8+ vs S8 Pro Ultra base difference
The "Plus" self-emptying system sucks out the robot dustbin's content right into the base.
The "Pro Ultra" base is the most advanced on the market. It has the following features:
- Self-emptying empties the robot's content
- Self-filling refills the water container during cleanups
- Self-cleaning cleans the bottom of the dock
- Self-washing washes the robot's mop after each use
- Self-drying dries the mop after washing, so it doesn't stink and is ready to be used the next time
All you have to do with the Pro Ultra is to fill the water container with water and throw away a dustbag about once a month.
Roborock S8+
The Roborock S8+ has a basic auto-empty station with a 2.5 L disposable dustbag and the same VibraRise mopping system. It has more power, two roller brushes instead of one, and upgraded obstacle avoidance technology.
So, in short, it is better for carpets or some small hard floor areas. If you are looking for a smaller station and don't need mopping as much, have a look at the Roborock S8+.
Roborock S8 MaxV Ultra
The premium lineup includes three models: Roborock S8 Pro Ultra, S8 Max Ultra, and S8 MaxV Ultra. Those have a better station compared to the S8+.
The Roborock S8 Pro Ultra has the same suction (compared to the S8+), navigation, and obstacle avoidance technology, an upgraded mopping system with two vibrating areas instead of one, and an all-in-one station. A good option for homes with hard floors if you need a better mopping experience.
The Roborock S8 Max Ultra has more power and a bigger water container, which means the robot is better for bigger mopping areas. The VibraRise raises the pad for up to 20 mm. The station includes a container with water detergent that automatically adds it to the clean water. Another new function is FlexiArm. When the robot gets close to the walls and corners, it extends the side brush closer for better cleaning results. Smart dirt detection senses how dirty the mopping pad is during washing to adjust the mop-washing duration. Also, when sensors detect dirty areas, the robot returns to wash them for a second time.
The Roborock S8 MaxV Ultra maps the floors faster and has the best object recognition system that identifies up to 73 objects. Additionally, it has even more power and DirtTech technology, thanks to which the robot recognizes dirty spots and intelligently switches vacuum mode or turns it off if it identifies juicy spills, making cleaning fully automated.
Roborock S8 MaxV Ultra
The best in the model line
The Roborock S8 MaxV Ultra is the most advanced model in the lineup and probably in the industry overall. Ideal if you are going to use mopping regularly and don't want to put much effort into it, since the base does all the work for you. The fully automated robot vacuum is ideal for those who don't want to think about setting everything up; the robot will do it for you.
Conclusion
The Roborock S8+ would be an option for carpeted homes or those who don't need mopping as much.
The Roborock S8 Pro Ultra is good for small hard floor areas.
The Roborock S8 Max Ultra is a great device with a bigger water container for bigger hard floor areas, it is smarter, has more power, and overall is a great device if you want it all in one machine.
The Roborock S8 MaxV Ultra is the best of the best. The most intelligent, the most automated, the most powerful, and is ideal for all kinds of surfaces or home sizes. The robot to set up once and let it go.
