3 sources2 derived$899.99as of Aug 1

Notebookcheck's review frames the Ecovacs Deebot T90 Pro Omni as flagship-level features at a mid-range price. Mopping is the strength, thanks to an Ozmo Roller 3.0 system that uses fresh water and cleans itself, and the review also singles out 30,000 Pa suction and TruEdge technology. Less good: navigation, corner cleaning, and the absence of a pure mopping mode. YouTube reviewers said it beats traditional pad-based mops in kitchens and high-traffic areas. Busy households are the fit; buyers who want basic mopping functionality or accurate navigation should look elsewhere.

Strengths
  • 30,000 Pa suction power comparable to flagship models
  • Ozmo Roller 3.0 mopping system with 27 cm extended microfiber roller
  • Fresh Flow power washing system keeps roller clean with fresh water during use
Watch-outs
  • No pure mopping mode available
  • Navigation and obstacle detection issues reported
  • Problems with corner cleaning performance

Roborock Saros 20
5 sources1 derived$1,599.99as of Aug 1

The Roborock Saros 20 delivers exceptional cleaning performance with its 36,000 Pa suction and dual mop system that adapts pressure based on mess level. Mark Ellis Reviews called it 'super easy to set up' and praised its 'brilliantly designed app,' while Vacuum Wars noted its 'standout mopping' and 'very high official suction rating.' However, both reviewers acknowledged it struggles with larger debris and heavily stained floors. This premium robot vacuum is ideal for users seeking a high-end, automated cleaning solution but may not suit those on a budget or with very challenging floor conditions.

Strengths
  • Easy setup and operation with brilliant app design
  • Top-class object avoidance and mapping capabilities
  • High suction power at 36,000 Pa for effective vacuuming
Watch-outs
  • Can struggle with larger bits of debris
  • Requires manual intervention for heavily stained floors
  • Premium price point of $1,499/£1,309

How they stack up

Ecovacs T90 Pro Omni

The Ecovacs T90 Pro Omni offers strong suction and a self-cleaning mopping system that outperforms the Dreame D30 Ultra and Mova P10 Pro Ultra in mopping consistency, but it lacks the advanced navigation of the Roborock Saros 20 and the AI features of the Narwal Flow 2. It's also more limited in its mopping modes compared to the Mova V50.

Roborock Saros 20

The Roborock Saros 20 excels in suction power and app usability, surpassing the Dreame X60 Max Ultra and Ecovacs T90 Pro Omni in both performance and ease of use. However, it's significantly more expensive than the Mova V50 and Lefant M5 Max, and its navigation and obstacle avoidance are less refined than the Narwal Flow 2's AI-driven system.
