Third-party reviews

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

What customers like about Xiaomi Mi Robot SDJQR02RR

  • Smart LDS and SLAM navigation maps the home accurately.
  • Excellent suction, especially on hard floors and for pet hair.
  • Excellent value compared with category flagships.
  • Advanced app features include zone cleaning and virtual walls.
  • Quiet operation during everyday use.

What customers don't like about Xiaomi Mi Robot SDJQR02RR

  • Navigation can struggle on very thick carpets or floors with large height differences.
  • No physical or virtual barriers are included in the initial package.
  • Brushes and filters require periodic maintenance.
  • The relatively small dustbin needs frequent emptying.
  • Off-limit zones cannot be set directly in the app without magnetic strips.

Verdict

The Xiaomi Mi Robot Vacuum (SDJQR02RR) is a first-generation smart vacuum cleaner that features 1,800 Pa of suction power, a 5,200 mAh lithium-ion battery delivering up to 2.5 hours of runtime, a 0.42-liter bagless dustbin, and an advanced Laser Distance Sensor (LDS) utilizing a SLAM algorithm for 360-degree room mapping. Main pros include its highly efficient systematic navigation, automated resume-from-breakpoint cleaning, long battery life covering up to 250 square meters, and seamless remote scheduling via the Mi Home app. However, its notable cons include a lack of built-in mopping functionality, a physical height of 96 mm that can cause it to get stuck under low furniture, and poor performance on high-pile carpets.
