The D4 model features a commercial-grade ET-1 electric power head with a 12-inch width, efficient at cleaning both carpets and hard floors. It easily removes pet hair, offers four-level manual brush height adjustment, and 180⁰ steering for superior maneuverability.
The power head includes tool-free brush roller removal, a clog removal door, and a safety warning light with automatic shut-off for jams. It also has a light indicator for optimal brush height and brush replacement. The vacuum has an LED display for monitoring suction power across settings, with slow rotation at lower settings, faster rotation at higher settings, and a blinking standby mode.
The dual-control handle provides easy suction adjustment for various cleaning needs and includes an on/off switch for the power head's brush roller for delicate cleaning tasks like fine rugs.
