Equipped with a powerful yet quiet 12-amp motor, this upright vacuum cleaner features patented WindTunnel 2 technology located in the floor nozzle, which forces the rotating brushes and airflow to work in harmony. It lifts and traps the dirt, keeping it from scattering back into the carpet, so dirt ends up in the cleaner not on the floor. With red and green lights, its embedded DirtFinder system indicates areas that may need more cleaning attention. The green "clean" light remains on while vacuuming except when the detector senses a larger amount of dirt; then the red "dirty" light will come on to suggest additional vacuuming in the area until the light changes back to green.

When in the upright position, the vacuum cleaner's agitator brush roll automatically shuts off, which allows all the suction power to be focused in the hose for effective above-floor cleaning. Attachments include a dusting brush, furniture nozzle, crevice tool, and a powered pet-hair cleaning tool. The unit's handle instantly converts into a telescopic wand, while its Tag Along grip helps guide the cleaner. Combined with the super stretch hose, it offers 12-feet of cleaning reach, eliminating the need to bend or stretch while cleaning.

The vacuum also provides a Breathe-Easy hygienic filter bag system, which makes changing the bag clean and simple. When removed, the bag automatically seals itself closed to keep dirt inside. It also traps 100-percent of dust mites, ragweed, and common grass pollens. The bag effortlessly slides back in from the front when replaced. Other highlights include a handle that adjusts for people of all heights, a headlight to illuminate the cleaning path, soft wheels, a carry handle, and a cord-rewind system that retracts 28 feet of cord quickly and easily at the push of a button. The vacuum cleaner measures approximately 14 by 15 by 43 inches.

By design, many conventional vacuum cleaners scatter dirt back into the carpeting because the rotating brushes and airflow don't work in harmony. But Hoover engineers discovered a way to make the rotating brushes and airflow work in harmony with the power of the wind. It's called WindTunnel technology. Located in the floor nozzle, Hoover WindTunnel technology actually lifts and traps the dirt, so it won't scatter back into your carpet, which means the dirt ends up in the cleaner, not on your floor.
