Of the two models, Roborock S7 Max Ultra has vibration mopping technology, when cleaning, it can wipe the floor at a frequency of 3,000 times/minute, which can thoroughly erase the stubborn stains on the floor and make the floor sparkle. And the timer back to wash the mop and mop lifting function ensures clean mopping and effectively avoids the dirty mop secondary pollution, when meeting the carpet, mop lifting can also avoid wet mop wet carpet. iRobot Roomba s9+ does not have the mopping function, which requires manual mopping, which is time-consuming and laborious.

When cleaning carpets, double rolling brush performance is better.
l The price PK, which vacuum robot cost-effective?

l Obstacle avoidance technology PK, what is the difference between the two models of obstacle avoidance performance?
In terms of obstacle avoidance, the S7 Max Ultra is equipped with Reactive Tech obstacle detection technology, which can accurately recognize obstacles and flexibly avoid them no matter day or night, so it won’t easily get stuck. iRobot Roomba s9+ is greatly affected by light in terms of obstacle avoidance. It can work normally in the daytime when there is enough light, but in the darkness of the night, the obstacle avoidance performance is poor, and it is easy to get stuck by obstacles. Into the dim light into the bottom of the sofa, under the bed cleaning, the performance is still not as good.
l The base station PK, omnipotent base station to make maintenance easier
Both models support the automatic dust collection function, which automatically empties the dust box after cleaning, so you don’t need to clean the dust box frequently.
However, the Roborock S7 Max Ultra base station is more versatile. In addition to automatic dust collection, it also washes dirty mops and dries them. You don’t need to wash the mop by hand, and you don’t have to worry about wet mops getting moldy or smelly.
