Ranked #6 in Best Robot Vacuums

Ecovacs T80S

4.2

5 sources1 derived$649.99as of Aug 1

The Ecovacs T80 Omni, also sold as the T80S, takes flagship OZMO mopping technology down to a mid-tier price. Reviewers praised the powerful suction, the pet hair removal, and a navigation system that combines LiDAR with 3D structured light. Mopping scored well above average, particularly in dried-stain tests. The recurring complaint was occasional stalling during reviewers' testing. It fits buyers who want premium features without the highest price tag; anyone on a tighter budget should look at lower-tier models.

Strengths

— OZMO roller-mop system with 200 RPM spinning and real-time rinsing for streak-free mopping
— 18,000 Pa brushless motor with ZeroTangle 3.0 brushes for strong pet hair and debris pickup
— AIVI 3D 3.0 with LiDAR navigation recognizing over 100 objects for intelligent obstacle avoidance

Watch-outs

— Occasional test-area stalls noted in performance evaluation
— Price is still several hundred dollars above entry-level models

Higher ratedRanked #3 in Best Robot Vacuums

Roborock Saros 20

4.4

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 T80S

The Ecovacs T80S offers a balance of suction and navigation with its LiDAR system, outperforming the Lefant M5 Max and Dreame D30 Ultra in these areas. However, it's less effective in mopping than the Mova V50 and lacks the AI features of the Narwal Flow 2, making it a mid-tier option for users seeking affordable premium features.

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.
