Mechanical audits of the AJELU Waterproof Sonicare system reveal a high-frequency vibration profile of 31,000 strokes per minute. The material composition utilizes food-grade ABS and TPE polymers, noted for being biologically inert. Analysis indicates that while the DuPont nylon bristles provide significant mechanical debris removal, the absence of a pressure sensor requires the user to monitor manual force to avoid surface abrasion.
The unit features an IPX7 moisture barrier, though long-term data indicates variability in seal longevity. The inclusion of eight replacement heads supports a consistent 90-day maintenance cycle, which is essential for preventing filament splaying. Specialists suggest using this high-vibration tool with a soft-bristled head to ensure gentle conditioning of sensitive areas.
