Reviews last updated: July 2026 · How we calculate this

What customers like about ECOVACS DEEBOT T9+

  • Powerful 3000 Pa suction that effectively picks up pet hair, crumbs, and fine dust particles.
  • Convenient auto-empty station providing a completely hands-free experience for up to 30 days.
  • Upgraded OZMO Pro 2.0 electric oscillating mopping system that scrubs floors thoroughly.
  • Efficient obstacle avoidance and TrueMapping 2.0 LiDAR technology that works well even in complete darkness.
  • Automatic carpet detection that increases suction on carpets and prevents the robot from crossing them while mopping.
  • Long battery life of up to 175 minutes, capable of cleaning homes with multiple bedrooms on a single charge.
  • Unique built-in mobile air freshener feature that leaves the home smelling fresh after a cleaning cycle.

What customers don't like about ECOVACS DEEBOT T9+

  • High ongoing maintenance costs due to the required purchase of proprietary single-use disposable mop pads and dust bags.
  • Frustrating companion app user experience with frequent reports of server downtime and deleted or reset floor maps.
  • Obstacle avoidance can occasionally be unreliable with small items, getting tangled in loose charging cables or wires.
  • Small internal 300ml dustbin on the robot itself, making it heavily reliant on the auto-empty base station.
  • The vacuum operates loudly when running on its highest 'Max' and 'Max+' suction settings or during base station auto-emptying.
  • Poor customer service and slow turnaround times reported by users experiencing hardware or replacement part issues.

Verdict

The ECOVACS DEEBOT T9+ is a high-performance 2-in-1 robot vacuum and mop featuring 3000 Pa suction power and the OZMO Pro 2.0 vibrating mopping system, which delivers 480 oscillations per minute for deep scrubbing. It utilizes TrueMapping 2.0 (LIDAR) for precise navigation and TrueDetect 3D for real-time obstacle avoidance, complemented by a 5200mAh battery providing up to 175 minutes of runtime. Key pros include its unique built-in air freshener, efficient 2.5L auto-empty station that holds 60 days of debris, and advanced 3D mapping capabilities via the ECOVACS Home App. However, common cons include a small 180ml water tank, the ongoing cost of proprietary disposable mopping pads and air freshener capsules, and occasional difficulties navigating complex furniture layouts like dining chair legs.
