Key Features 

1250-Watt Commercial-Grade Motor

At the heart of the D4 Premium is a high-efficiency, 1250-watt motor that generates powerful, consistent suction. It's engineered for continuous use and optimized for long-term performance, delivering professional-grade results in any home.

ET-1 Power Head with Height Adjustment

The included ET-1 motorized powerhead features four-level manual height adjustment, a 12-inch cleaning path, and a brushroll shutoff for transitioning between carpets and hard floors. Its precision cleaning ability makes it ideal for plush carpet, area rugs, and pet hair removal.

50-Foot Cleaning Radius

One of the most generous in the industry, the D4 Premium offers a full 50-foot cleaning radius thanks to a 40-foot cord, telescopic wand, and long hose—allowing you to clean large spaces without unplugging or moving frequently.

S-Class Filtration (HEPA Equivalent)

The fully sealed S-Class filtration system captures 99.97% of airborne particles down to 0.3 microns. This includes dust, dander, pollen, and allergens—making the D4 Premium ideal for households concerned about air quality.

Digital Suction Control with LED Display

A unique feature of the D4 Premium is its digital suction control. Located on the canister body, the rotary control and LED indicator allow you to fine-tune suction power for delicate surfaces or deep-cleaning applications.

Ultra-Quiet Operation

Despite its powerful motor, the D4 operates at a whisper-quiet level thanks to precision airflow engineering and acoustic insulation—making it ideal for households with children, pets, or sound-sensitive members.

1.5-Gallon Filter Bag Capacity

Its oversized, multi-layer filter bag holds up to 1.5 gallons of debris—perfect for extended cleaning sessions. The hygienic self-sealing design keeps dust contained and eliminates exposure when changing bags.

Onboard Tools & Storage

The D4 Premium features integrated storage for its dusting brush, crevice tool, and upholstery nozzle. All tools are conveniently located for quick swaps during cleaning.

Built for Cleaner Air

The sealed filtration and hospital-grade filters ensure allergens, pet hair, and fine dust stay locked inside the vacuum. Combined with its quiet, dispersed exhaust system, the D4 helps promote healthier indoor air quality with every use. 

Built to Last in Germany

SEBO builds vacuums for commercial-grade endurance. The D4 Premium is constructed with high-impact ABS plastic, stainless steel, and long-life components—designed for 15–20 years of reliable home use under proper care.
