Central Vacuum Cleaner

Overview

Description

Central vacuum systems are popular in large homes and regions like North America and parts of Europe due to their advantages over traditional vacuum cleaners, such as greater suction power, enhanced convenience, ease of use, and quieter operation. Conventional central vacuum systems typically use AC motors with power ratings from 1000W to 1700W for stronger suction. In contrast, this central vacuum cleaner uses a brushless DC (BLDC) motor, delivering the same suction power and performance with reduced energy consumption. This system also utilizes power line communication (PLC) technology for remote control, enhancing operational efficiency and user convenience.

System Benefits​:

  • High-performance BLDC control offers energy-efficient operation while maintaining stable suction power for consistent performance.
  • The Cool Phoenix 4 PLC modem IC enables remote control and monitoring of the BLDC motor through power lines, eliminating the need for additional wiring.
  • Instant system health feedback on the vacuum hose display provides performance awareness and enhances the user experience.
