Obstacle Avoidance + 3D SLAM in One: DEPTRUM Powers the Global Launch of Dreame L60 Ultra

On 28 April, Dreame officially launched its flagship robot vacuum, the L60 Ultra, in Silicon Valley, USA. Equipped with DEPTRUM’s latest Nebula 280 depth camera, the product achieves the industry’s first mass-produced single 3D ToF module that combines obstacle avoidance and SLAM, marking a new stage in robot vacuum visual perception.

As a core partner to Dreame, DEPTRUM tailored an AI 3D ToF full-scenario visual perception solution for the L60 Ultra. Built on its self-developed sToF technology, the solution uses just one sensor to simultaneously handle whole-home obstacle avoidance and 3D SLAM, comprehensively addressing core pain points in navigation, obstacle avoidance, scene recognition and intelligent interaction — helping the product build differentiated competitiveness.

For navigation and mapping, the Nebula 280 provides more stable and precise perception support for the Dreame L60 Ultra. Compared with conventional top-mounted LDS LiDAR, the L60 Ultra achieves high-precision real-time mapping and seamless navigation using a single ToF depth camera at the front of the chassis. Eliminating the top LDS radar structure not only enables a slimmer body but also breaks spatial limits on cleaning capability: the robot easily reaches under beds and sofas and maintains stable perception and precise navigation in tight spaces, delivering truly corner-to-corner cleaning.

For obstacle avoidance, the Nebula 280 uses an area-array structured light 3D reconstruction algorithm to achieve millimeter-level avoidance accuracy and recognize more than 280 types of household objects. Compared with conventional 3D ToF solutions, the Nebula 280 effectively resolves multipath interference: even with black skirting boards, thin chair legs and glossy floor tiles, it precisely reconstructs object boundaries and enables edge-hugging cleaning without collisions.

Leveraging powerful AI multimodal vision, DEPTRUM also helped the Dreame L60 Ultra deliver several industry-leading intelligent recognition innovations. Through multimodal image fusion, the robot accurately identifies different forms of solid and liquid stains and applies targeted re-washing and re-mopping, closing the loop on cleaning performance. For pet-owning households, the system combines a whole-home 3D semantic map to identify pet activity areas and specific cleaning needs, supporting smarter customized cleaning strategies for a truly personalized experience in every zone.

When encountering obstacles of varying heights such as thresholds and sliding rails, the Dreame L60 Ultra accurately determines whether to cross or go around, greatly reducing stuck situations, accidental collisions and missed areas for a high-quality cleaning experience with zero stuck incidents and zero accidental collisions. Using AI visual perception to identify carpet types, the robot also intelligently raises the mop pad, removes it or boosts suction, automatically matching the optimal cleaning mode for more precise, efficient cleaning and a better user experience.

The global launch of the Dreame L60 Ultra is not only an important breakthrough for Dreame in premium intelligent cleaning, but also reflects DEPTRUM’s technology innovation and leadership in the robot visual perception space. As the robotics industry accelerates toward intelligence, scenario-specific applications and globalization, DEPTRUM is using its leading visual perception capabilities to continuously move robot vacuums into the 3D SLAM era.
