What does the AUTO smart dust sensor of this cordless smart vacuum cleaner do?

The AUTO smart dust sensor uses a combination of advanced optical sensing and airflow analysis technology. The system can perform real-time analysis of the concentration and particle size distribution of particles in the inhaled air through a built-in high-precision laser detection unit and a micro-airflow monitoring system. Its workflow can be divided into four key stages. The first is the real-time monitoring stage. The sensor detects the airflow at a high-speed scanning frequency of 1,000 times per second, and uses the laser scattering principle to accurately identify dust particles larger than 0.3 microns, including tiny pollutants such as pollen and mite excrement, and combines the airflow speed to calculate accurate dust concentration data.

In the data judgment stage, the built-in AI algorithm will intelligently divide the cleaning scene into three levels according to the detected dust concentration: low concentration scene, medium concentration scene and high concentration scene. The system will also synchronously detect changes in ground resistance and accurately distinguish the physical properties of different materials such as hard floors and high-pile carpets.

After entering the dynamic response stage, the system controls the motor speed through precise PWM technology, so that the suction can be adjusted steplessly and smoothly between 30AW-150AW. When a low-concentration area is detected, it automatically switches to an energy-saving mode of about 50AW, which can significantly increase the battery life by 40%; and when encountering sudden high-concentration dust, such as spilled coffee powder, the system can instantly burst out 150AW super suction to ensure efficient cleaning within 3 seconds. At the same time, the roller brush speed will also be synchronously adjusted intelligently within the range of 500-3000 rpm to effectively avoid the problem of carpet fiber entanglement.

The final continuous optimization stage demonstrates the system's learning ability, and grasps the user's usage habits by accumulating historical cleaning data. For example, the system can recognize that the bedroom floor will accumulate more hair loss every Wednesday, so as to preload the strong mode in advance; or establish a special quick response strategy for the frequent biscuit crumbs in the children's room, so as to achieve a personalized cleaning experience that is more intelligent with use.

This product uses the industry's first dual-channel detection technology, and monitors dust concentration through optical sensors and detects floor materials through pressure sensors, which perfectly solves the pain point that traditional single sensors are prone to misjudgment. For example, traditional sensors often misjudge "low dust but high resistance" carpet environments as dirty areas, while this product can accurately distinguish physical resistance from real dirt to ensure accurate matching of cleaning modes.

The second major innovation is the breakthrough of the millisecond response system. The entire process from detection to adjustment takes only 0.2 seconds, which is 15 times faster than manual gear switching. The rigorous test data of the laboratory shows that when the vacuum cleaner moves through a dust pile within a distance of 1 meter, the suction force can be quickly increased from 60AW to 130AW in an amazing 0.3 seconds, ensuring that no dirt is missed.

The third major innovation is reflected in the energy efficiency ratio optimization algorithm. Through advanced load balancing technology, the system significantly reduces energy consumption while ensuring excellent cleaning power. Actual measured data shows that the energy consumption of processing 5 grams of dust is 27% lower than that of the traditional fixed power mode, truly achieving a perfect balance between high efficiency and energy saving.

In the cleaning scene of a pet family, the sensor can intelligently identify the hair gathering area, automatically increase the suction to more than 120AW, and start the reverse rotation anti-entanglement mechanism. This function saves a lot of manual cleaning time for pet owners, and effectively avoids the problem of hair clogging, making cleaning work easy and efficient.

For the special user group of allergic people, the sensor will automatically trigger the 99.99% high-efficiency filtration mode for 0.3 micron allergens. After professional testing, the air cleanliness discharged in this mode can meet strict medical-grade standards, providing all-round health protection for sensitive people.

In the special cleaning scene after decoration, the sensor can continuously monitor the cement dust concentration and intelligently extend the duration of the strong mode. Actual usage data shows that this function increases the efficiency of a single cleaning by 60%, greatly shortens the complicated cleaning work time after decoration, and makes it easier and more convenient to prepare for the move-in of a new house.
