So what has the S8 brought into the table?
Roborock s7 vs s8 series
- Dual roller system. Upgraded dual roller rubber brushes system gets deeper into carpets ensuring better pickup
- Roller riser. In mopping mode, the robot automatically raises rollers and the mopping pad when steps on carpet if you set it to avoid cleaning carpets.
- Upgraded vibrorise. The newest system is wider and covers a bigger area at once
- 30% faster charging
- Stronger 6k Pa suction
- Cleaning carpets twice with mopping on. The mop lifts automatically on carpet so the robot vacuums twice (turned off by default)
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
There are four cleaning options:
- vacuum only. The robot raises the pad
- vacuum and then mop. The robot raises the pad letting the robot to vacuum and then drops it down for mopping
- both at the same time. Doesn't rise the brush or mop when cleans
- mop only. Rises the brushrolls for mopping
The mopping system vibrates pressuring the pad to the floor so it performs better with sticky stains. The S8 and S8+ has the standard vibrating mopping system while the S8 Pro Ultra has a wider vibrating area so it covers more at once. It lifts the mopping pad when detects carpet (not a thick one tho) so it can vacuum the carpet without damping it.
The double roller brush system ensures better pickup and deeper carpet clean 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.
Roborock S8 vs S8+ vs. S8 Pro Ultra the difference
The Roborock S8 is the cheapest. It lacks the brush raiser and a self-emptying base. Its VibraRise mopping system is the one we've seen in the previous S7 series.
The Roborock S8+ is the S8 with a self-emptying base.
The Roborock S8 Pro Ultra. The Pro Ultra base washes the pads, dries them out, auto-fills the mopping container, sucks out the dustbin's content, and cleans the base's bottom on its own. Additionally, the S8 Pro Ultra rises the brush system which the S8 and S8+ do not do.
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
Basically, 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 all the bells and whistles of a premium robot vacuum yet does not come with a self-emptying station.
Roborock S8+
The Roborock S8+ does not have the additional features of the S8 Pro Ultra. It is ideal for homes with carpets mostly or pet owners. Still capable of mopping yet is not as effortless to use as the Pro Ultra version.
Roborock S8 Pro Ultra
The Roborock S8 Pro Ultra is the most advanced model in the lineup and probably in the industry overall. Ideal if you are going to use mopping on a regular base and don't want to put much effort into it since the base does all the work for you.
Conclusion
The newest Roborock S8 is a better version of one of the best existing robots, the Roborock S7. It has more power, it is smart, and has lots of different cleaning modes.
