How efficient is the Centrifugal Fan Square vacuum cleaner when vacuuming different floor materials?
Publish Time: 2025-10-02
With the prevalence of smart homes, robot vacuums have become essential cleaning aids in modern homes. The centrifugal fan, the powerhouse of their cleaning system, directly determines the strength and stability of their vacuuming capabilities. In recent years, the Centrifugal Fan Square has been widely adopted in mid- to high-end robot vacuums due to its compact design and ample space for optimized air ducts.1. Structural Advantages of the Centrifugal Fan SquareCompared to traditional circular fans, the Centrifugal Fan Square achieves more efficient airflow distribution within a limited footprint. Its multi-blade, backward-inclined impeller generates powerful centrifugal force when rotating at high speed, drawing air in from the center and expelling it radially at high speed, creating a stable negative pressure airflow. The square housing seamlessly integrates with the robot's internal air duct, reducing airflow bends and vortex losses, thereby improving overall air pressure and air volume output efficiency. This optimized structure enables the fan to maintain high suction power while minimizing energy consumption, providing robust power for complex floor environments.2. Hard Floors: Efficiently Removes Fine Dust and DebrisOn hard floors like tile, marble, and wood floors, contaminants like dust, hair, and debris cling primarily to the surface and are easily picked up by airflow. The Centrifugal Fan Square, with its high air pressure, quickly creates a strong negative pressure zone at the suction port, instantly drawing floor particles into the dust bin. Its air duct design typically uses a side brush and a main brush to work together. The main brush stirs up the dust, while the side brush directs it into the suction port, while the fan provides continuous and stable suction support. Tests have shown that on hard floors, vacuum cleaners equipped with the high-performance Centrifugal Fan Square achieve a vacuuming efficiency of over 98%, with particularly effective removal of fine dust and pet hair.3. Short-pile Carpets and Floor Mats: Penetrates the Fiber Layer for a Deep CleanCarpeted floors are one of the most challenging surfaces for vacuum cleaners. Dust, dander, and food debris can easily become embedded deep within the fibers, making them difficult to completely remove with standard suction. The Centrifugal Fan Square improves the balance between air pressure and air volume, enhancing airflow penetration and allowing suction to penetrate deep into carpet fibers. Some high-end models also feature intelligent suction adjustment. When a sensor detects a carpet, the fan speed automatically increases, creating a "Carpet Boost" mode. This boosts fan output by 30%-50%, ensuring deep-seated dirt is effectively extracted and avoiding the problem of "clean surface, hidden dirt underneath."4. Long-pile Carpets and High-Friction Floors: The Challenge of Suction and Brush Head SynergyOn long-pile carpets or high-density woven mats, the fan not only faces greater air resistance but also the increased rotational resistance of the brush head. In these situations, the Centrifugal Fan Square's high efficiency advantage is even more pronounced. Its stable air output maintains a constant negative pressure at the suction port, preventing a sudden drop in suction due to air duct blockage or increased resistance. Furthermore, the optimized matching of the fan and motor ensures stable operation even under high loads, preventing overheating and shutdown. Combined with a main brush system that can be raised or lowered, or automatically adjusted, it achieves a synergistic combination of "strong suction and low resistance," minimizing lag and energy consumption.5. Intelligent Control: Adapting to the Dynamic Needs of Multi-Surface MaterialsModern robot vacuums are commonly equipped with environmental sensing systems that can identify surface types in real time and adjust the fan's operating mode. The Centrifugal Fan Square, with its fast response time and wide speed range, is an ideal choice for intelligent suction power adjustment. For example, it uses medium suction on hard surfaces to save energy and reduce noise, while automatically switching to high-power mode on carpeted areas, ensuring effective cleaning while extending battery life. Some models also support app-based speed customization, allowing users to flexibly adjust speeds based on the floor composition of their home for personalized cleaning.6. Balancing Noise Reduction and Energy EfficiencyHigh suction power often comes with high noise levels, but the Centrifugal Fan Square achieves both improved efficiency and effective noise control through optimized impeller curvature, added sound-absorbing materials, and improved air duct sealing. In standard mode, operating noise is kept below 65 decibels, ensuring no disturbance during nighttime cleaning. At the same time, its high energy efficiency ratio reduces energy consumption per unit of suction power, extending cleaning time and enhancing the overall user experience.As the core power source of the robot vacuum, the Centrifugal Fan Square, with its structural advantages and intelligent control capabilities, demonstrates exceptional vacuuming efficiency on a variety of floor materials, including wood floors, tiles, and carpets. It's not just powerful, but also intelligent and powerful—it dynamically adjusts its operating mode based on floor characteristics, achieving efficient, energy-saving, and silent cleaning on all surfaces.
