Dreame L40s Ultra AE (Dreame) vs 3i S10 Ultra (3i)

Dreame L40s Ultra AE delivers strong cleaning on various surfaces with its sensor suite and AI navigation, showing above-average results in debris pickup and mopping tests. The 3i S10 Ultra excels at handling large debris like mulch without clogging, thanks to its sweep/roller design and high autonomy in real-world scenarios. Both perform well on pet hair and mixed floors, but Dreame edges in suction benchmarks while 3i prioritizes tangle-free operation.

Dreame L40s Ultra AE uses LiDAR plus RGB camera and 3D structured light for superior obstacle avoidance, scoring above average in tests compared to other models. 3i S10 Ultra relies on fixed dToF LiDAR with dual 3D structured light and AI algorithms, enabling reliable mapping and fewer stuck incidents in complex homes. Dreame's visual enhancements provide better precision in cluttered environments, while 3i focuses on consistent coverage.

Both robots feature lithium-ion batteries with 2-3 year lifespans and 0.3 m/s speed, supporting efficient cleaning cycles. Dreame L40s Ultra AE achieves top battery efficiency at 2.43 square meters per minute, estimating 2400 square feet per charge. 3i S10 Ultra matches closely in runtime tests, performing well in larger areas without significant differences noted.

Dreame L40s Ultra AE runs Dreame OS with AI navigation and app-based firmware updates for seamless control. 3i S10 Ultra's proprietary OS integrates AI cleaning algorithms, 3i app ecosystem, and broad voice control with Alexa and Google Assistant. Both offer autonomous operation, but 3i's ecosystem emphasizes hands-off setup.

Dreame L40s Ultra AE measures 35x35x9.7 cm at 4.1 kg, slightly slimmer for better edge access. 3i S10 Ultra is taller at 10.5 cm and 4.5 kg, with added carpet detection aiding transitions. Maintenance is straightforward for both via apps, with Dreame's sensors reducing manual interventions.

Dreame L40s Ultra AE fits families and pet owners in mixed-floor homes, leveraging AI for versatile cleaning. 3i S10 Ultra suits large homes and pet households, excelling in autonomous debris handling across expansive areas. Selection depends on home layout and debris types.

Dreame L40s Ultra AE at USD 700-900 provides strong performance-to-price ratio with advanced sensors. 3i S10 Ultra's USD 1,099-1,499 premium reflects robust build and debris capabilities. Dreame offers better entry-level value for most users.
