Recently, Roborock Technology launched its new-generation flagship robot vacuum and mop cleaners, the G20S and G30, which focus on intelligent cleaning and user-friendly human-machine interaction (HMI). Among them, the G20S integrates a high-precision 3D-TOF solid-state LiDAR, replacing the traditional external LDS (Laser Distance Sensor). This upgrade enhances the accuracy and stability of navigation technology, enabling flawless obstacle avoidance. Additionally, the integration of multiple sensors and high-sensitivity touch detection allows the device to move freely in low-clearance spaces, taking cleaning coverage to a new level. Equipped with the RRmind GPT large model, the product supports natural voice interaction and other advanced features, leading the way in the intelligent evolution of cleaning robots.
Roborock Technology is a brand under Beijing Roborock Technology Co., Ltd., an intelligent hardware manufacturer dedicated to technological innovation. Its core R&D team consists of technical experts with years of experience from renowned companies such as Microsoft, Intel, ARM, and Nokia. Roborock is a leading global enterprise that has widely applied LiDAR technology and related algorithms to the field of intelligent robot vacuum cleaners.

Product Introduction
Both flagship robot models adopt multiple Awinic products. Below is a breakdown by functional modules such as Human-Machine Interaction and General Components:
Extended Link
Awinic Robot Vacuum Cleaner Solution: Awinic launches application solutions for robot vacuum cleaners, featuring four major product portfolios (including human-machine interaction and intelligent detection) to empower a quality life.
1. Human-Machine Interaction (HMI)
Backed by years of technical accumulation, Awinic’s HMI solutions boast a comprehensive product lineup, including breathing light drivers and audio PAs (Power Amplifiers), enabling tailored products to meet diverse customer requirements.
Breathing Lights
Dynamic breathing lights can display different light effects in response to the user’s various voice interaction commands, delivering a personalized visual experience.
After over a decade of development, Awinic’s breathing light drivers cover 3 to 216 channels and provide full-cycle services including driver chips, light effect algorithms, and software debugging – simplifying the implementation of customer solutions. These products have been adopted and put into mass production by multiple leading manufacturers.
Overview of the AW20XXX High-Performance Matrix-Type Breathing Light Driver Series (Taking the 72-channel model AW20072 as an example):

Audio
Voice interaction is another key HMI method. Beyond basic voice assistant conversations, the integration of AI recognition technology enables the robot to easily understand complex, continuous, or ambiguous commands – making voice interaction more natural. This, in turn, imposes new demands on the audio link.
