The AIRBELT E3 Premium offers much more! In addition to a parquet brush, it includes the commercial-quality ET-1 electric power head that cleans both carpets and hard floors, has excellent pet hair removal, and the extension side of its L-shaped contour makes cleaning under counters easy. The power head also offers a super-low 3.5-inch horizontal cleaning profile, tool-free brush roller removal, and automatic shut off due to brush roller obstructions, while its tapered suction hose increases airflow velocity and decreases clogs. Foremost among its many features, the E3’s dual-control handle provides unsurpassed user convenience with an integrated on/off switch for the brush roller, a slider switch that adjusts suction power, and it facilitates effortless control of the power head’s 180⁰ steering ability.
