Xiaomi Robot Vacuum S20 +

The S20+ delivers 6,000Pa suction power and dual rotary mops, matching the X20+; the S20 only has 5,000Pa and a single static mopping pad. You can choose from four cleaning modes and four suction speeds, and an edge brush helps to clean hard-to-reach areas. The robots all use LDS laser navigation with obstacle avoidance technology. Plus, the S20+ can detect a carpet and lift the mop accordingly, as can the X20+. With a 5,200mAh battery, larger than the 3,200mAh power pack in the S20, the S20+ can run for up to 170 minutes between charges. The main difference between the X20+ and the S20+ is that the latest model only charges at its dock. In contrast, the older model’s charging station also offers basic self-cleaning features like emptying the dustbin.

You can remotely control the vacuum via the Xiaomi Home or Mi Home app and with Amazon Alexa or Google Assistant voice commands.
