A precision positioning part for vacuum cleaner main brushes that locks securely in place without affecting cleaning performance. Key benefits Secure, precise fit: The part ensures an accurate card/locking position and remains firm and reliable after installation, preventing brush displacement during use. Maintains suction performance: Designed not to obstruct airflow or change the vacuum cleaner's suction output, so cleaning power remains consistent. Lightweight material: Constructed from a light material that does not add noticeable weight to the equipment or strain moving parts. Wide compatibility: Fits a variety of main brushes in different sizes, allowing use across multiple brush models without modification. How it solves common problems Prevents brush movement and rattling that reduce cleaning effectiveness or cause wear. Avoids reduced suction that can occur with poorly designed adapters or replacements. Keeps overall equipment weight low to protect bearings and motors, prolonging component life. Simplifies parts interchange by working with different main brush sizes, reducing the need for multiple adapters. Practical applications Home vacuum maintenance: worn positioning parts on household vacuums to restore a secure brush fit without changing suction performance. Pet hair and carpet cleaning: Use with different main brush sizes when switching between brush types for carpets and hard floors while maintaining stable performance. Commercial cleaning equipment: Compatible across brush models used in janitorial or light commercial vacuums, allowing fast part swaps during routine service. Technical attributes Function: Precise positioning and secure locking of the main brush assembly. Compatibility: Works with a variety of main brushes of different sizes. Material: Lightweight construction that does not add meaningful weight to the equipment. Performance: Designed not to affect vacuum suction output and to remain firm after installation.
