Third-party reviews

Based on ratings from across the web.
Reviews last updated: July 2026 · How we calculate this

What customers like about Xiaomi Robot Vacuum X20+

  • Excellent value for money and price-to-performance ratio
  • Strong suction power effective on carpets and hard floors
  • Efficient navigation and mapping system, rarely gets stuck
  • All-in-one base station provides automatic dust emptying, mop cleaning, and drying
  • Good, sturdy build quality of both the robot and station
  • Two rotating mops provide effective cleaning (buffing effect)

What customers don't like about Xiaomi Robot Vacuum X20+

  • Mopping relies solely on water; cannot use cleaning solutions
  • Station uses cold air for drying, which can take time
  • Obstacle avoidance can struggle with smaller objects like cables
  • No automatic carpet detection sensor; carpets must be marked manually in the app
  • Base station noise is noticeable when emptying the dustbin

Verdict

The Xiaomi Robot Vacuum X20+ is an all-in-one automated cleaner featuring 6,000 Pa suction power, LDS laser navigation, and an S-Cross structured light obstacle avoidance system. Its automated Omni base station is equipped with 4L clean and dirty water tanks, supports 10-second auto-dust emptying with a 2.5L disposable bag that lasts up to 75 days, and features a dual-pad mop washing platform spinning at 180 RPM with cool-air drying. Main advantages include exceptional hands-free maintenance, precise 360-degree home mapping via the Mi Home app, and smart 7mm auto-mop lifting to safeguard low-pile carpets. However, significant drawbacks include the total absence of an internal water tank on the robot—forcing frequent returns to the dock to re-wet the pads—sluggish cool-air drying times, a lack of automated carpet detection, and difficulty cleaning tight corners or dealing with tangled hair on the main brush.
