This is an INGCO industrial aspirator blower (likely model AB4018 or similar 400W-650W model) designed for clearing debris and dust.
It features a dual-function design, allowing it to act as both a blower to move leaves and a vacuum to collect them into the included dust bag.
The tool is equipped with a variable speed control (typically 0-14,000 or 16,000 RPM) to adjust the airflow for different tasks.
