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

What customers like about DreameBot D9

  • Excellent value for money as a budget-friendly hybrid model
  • Strong suction power that effectively handles debris on hard floors and carpets
  • Accurate LiDAR navigation and room mapping in darkness
  • Large dustbin capacity requiring less frequent emptying
  • Operates quietly compared to many key competitors

What customers don't like about DreameBot D9

  • Lacks advanced front obstacle-avoidance sensors for low-profile objects like cables and socks
  • Struggles to cross high thresholds or thick floor transitions without getting stuck
  • Occasional software glitches, including map drifting, shifting, or losing saved layouts
  • The official app interface can be unintuitive with poor text translations
  • Fragile or awkwardly designed opening mechanism on the dustbin

Verdict

The DreameBot D9 is a 2-in-1 robot vacuum and mop featuring a 3,000 Pa suction motor, advanced LiDAR laser navigation, and a large 5,200 mAh battery that provides up to 150 minutes of runtime to cover areas up to 250 m² on a single charge. Its main characteristics include an electronic 270 mL water tank, a 570 mL dustbin capacity, a 20 mm obstacle-climbing threshold, and seamless integration with the Mi Home app for setting customized virtual walls and no-go zones. Key pros include its strong suction power on both hard floors and carpets, efficient straight-line mapping, and quiet operation; however, it has some cons, such as occasionally getting stuck in tight or low spaces, lackluster agitation compared to premium competitors, and minor software glitches during multi-map saving.
