The Ecovacs T80 Omni positions itself in the mid-range home vacuum cleaner market with a price of $700-$900. It features embedded dToF LiDAR navigation combined with AIVI 3D obstacle avoidance and multi-level SLAM mapping, distinguishing it through advanced sensor fusion including TruEdge 3D edge sensor and Lingchan 3.0 anti-tangle technology. This setup supports precise mapping and edge cleaning in varied home environments.
The Dreame L40s Ultra AE targets the same $700-$900 price segment for home vacuum cleaners, emphasizing AI-enhanced SLAM navigation with RGB camera and 3D structured light. Its lighter 4.1 kg weight and 0.3 m/s speed provide efficient mobility, setting it apart with Dreame OS firmware updates via app. It maintains core functionalities like cliff detection while offering a compact 35 x 35 x 9.7 cm design.
Detailed Analysis

Design & Build Quality
Ecovacs T80 Omni measures 35.0 x 35.0 x 9.8 cm and weighs 4.5 kg, slightly taller and heavier than Dreame L40s Ultra AE at 35 x 35 x 9.7 cm and 4.1 kg. Both share similar circular footprints suited for home navigation under furniture. The marginal size differences impact minimal on storage but Dreame's lighter build may ease manual handling.

Mobility & Navigation
Ecovacs T80 Omni uses embedded dToF LiDAR with multi-level SLAM mapping for structured navigation. Dreame L40s Ultra AE employs AI-enhanced SLAM with RGB camera and 3D structured light at 0.3 m/s speed. Ecovacs emphasizes multi-floor mapping while Dreame focuses on precise obstacle handling in single-level homes.

Sensors & Perception
Ecovacs T80 Omni includes dToF LiDAR, single camera, LED, 3D structured light, cliff, bump, and TruEdge 3D edge sensors. Dreame L40s Ultra AE has LiDAR, RGB camera, 3D structured light, cliff, and bump sensors. Ecovacs offers more sensor types for edge detection, while Dreame prioritizes RGB for visual perception.

AI Capabilities
Ecovacs runs Proprietary Ecovacs OS with Lingxi 2.0 AI, Lingchan 3.0 anti-tangle, and AIVI 3D avoidance. Dreame uses Dreame OS with AI navigation and app firmware updates. Ecovacs integrates specialized anti-tangle and edge AI, contrasting Dreame's focus on SLAM enhancement.

Battery & Power Efficiency
