The Xiaomi Robot Vacuum X20 Pro measures 350 × 350 mm with a height of 97 mm and weighs 3700 g, giving it a compact footprint suitable for navigating under furniture. It includes both a HEPA filter and an allergy filter, and operates at an audible noise level of 60 dB. The docking station, with a volume of 80396.4 cm³, supports automatic dust emptying with an estimated empty interval of 75 days, reducing how often manual intervention is needed. The robot is compatible with Google Assistant and Amazon Alexa for voice control, and comes backed by a 2-year warranty.
The X20 Pro comes equipped with mapping and route mapping, allowing it to build and follow structured cleaning paths, while no-go zones and virtual barriers let users define areas the robot should avoid. Carpet detection triggers automatic mop raising when the unit transitions onto carpeted surfaces, and an anti-stuck mechanism along with an anti-fall sensor keep navigation reliable across different floor layouts. Mopping is supported with adjustable water levels, and the mop pad can be both raised and dried automatically, rounding out a comprehensive wet-cleaning setup. The robot is self-emptying and returns to its dock autonomously, with scheduled cleaning and full smartphone remote control available through a Wi-Fi connection supporting both Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac). An obstacle sensor adds another layer of navigation awareness, while problem area cleaning allows it to give extra attention to dirtier spots. It does not include voice prompts.
The X20 Pro has a 0.4-litre dustbin and uses bags for dust collection, with a built-in indicator that signals when the bag is full. Washable filters are included, and the unit automatically adjusts its height to accommodate different floor surfaces. It does not feature a display or twin side brushes.
The X20 Pro delivers 7000 Pa of suction power and supports four cleaning modes, giving users flexibility over how thoroughly each session runs. It cleans all floor types and includes mopping as part of its cleaning capability. The unit does not have a dirt sensor or an electrostatic filtration system.
The X20 Pro is powered by a 5200 mAh battery that supports up to 160 minutes of runtime per charge, with a full recharge taking approximately 6.5 hours. Operating power consumption sits at 55W, and the battery is not removable.
