Reviews last updated: July 2026 · How we calculate this

What customers like about Ultenic D6s

  • Strong 3000Pa suction power with automatic carpet boost
  • Effective 2-in-1 sweeping, vacuuming, and sonic vibration mopping
  • Low 7.4 cm profile allows for cleaning under furniture
  • Good app functionality, including mapping and voice control (Alexa/Google Home)
  • Includes a remote control as an alternative to the app
  • Decent battery life (up to 100 minutes)

What customers don't like about Ultenic D6s

  • Standard suction mode is not very powerful; requires boost mode
  • Boost mode drains the battery faster
  • Uses infrared sensors rather than advanced LiDAR, affecting navigation accuracy
  • Entry-level cleaning performance compared to higher-end models
  • App pairing or purchasing issues mentioned in user experience

Verdict

The Ultenic D6s is a 3-in-1 robot vacuum and mop combo featuring a slim 7.4 cm profile, a 2,600 mAh battery offering up to 100 minutes of runtime, and a 490 ml combined dust and water container. Main pros include its powerful 3000Pa maximum suction with automatic carpet detection boost, a SonicTrue vibration mopping system that delivers up to 3,000 scrubs per minute, and versatile control options via a remote control, smartphone app, or voice assistants like Alexa and Google Home. However, notable cons include its basic gyroscope-based SLAM navigation rather than precise LiDAR mapping, which can sometimes lead to inconsistent room mapping and occasional difficulties finding its charging base.
