- High-output 31,000 Pa suction delivering an 84% carpet sand removal rate
- Dual HD camera array backed by a 10-TOPS VLM processor detecting objects down to 5 mm (0.20 in)
- Multi-stage automated dock featuring 212°F (100°C) hot water washing and hot air drying
- Anti-tangle roller brush design with zero hair tangles recorded in testing
- Failed obstacle avoidance on 4 out of 24 standardized test objects
- Unconventional floor coverage pathing patterns observed during navigation
Overview
Edge-AI compute and high-displacement mechanical extraction define the core architecture of the Narwal Flow 2. Driven by a dedicated 10-TOPS neural processing unit, the dual HD camera vision subsystem executes an on-device Visual Language Model (VLM) engineered to identify low-profile floor obstacles down to 5 mm (0.20 in). Mechanical pickup relies on a motor assembly rated at 31,000 Pa of suction, paired with an anti-tangle roller brush that demonstrated zero hair wrap during validation and achieved an 84% sand removal rate in standardized carpet deep-cleaning assessments.
Mopping operations are handled by the integrated FlowWash Mopping System, supported by a multi-stage docking station that manages automated debris emptying, fluid replenishment, and self-cleaning. Thermal management centers on the dock’s fluid heating element, which elevates wash water to 212°F (100°C) for sanitary mop pad cleansing before engaging an active hot-air drying cycle to inhibit microbial buildup. The chassis and base station incorporate rigid composite polymers designed to withstand repetitive mechanical docking cycles and thermal stress from continuous high-temperature fluid handling.
In real-world deployment, the platform exhibits solid mechanical durability, but its navigational logic reveals areas requiring firmware optimization. Standardized obstacle avoidance trials recorded 4 collisions out of 24 presented test objects, alongside an unconventional pathing pattern observed during open-floor coverage routines. While the vacuum and mop mechanics deliver reliable physical extraction, edge-case spatial tracking remains dependent on ongoing software iterations to match the hardware’s processing capabilities.
