Key Features

1250-Watt Suction Motor

The SEBO K3 Premium is powered by a 1250-watt motor that delivers powerful, consistent suction across all flooring types. Whether you’re cleaning plush carpets or smooth tile, the K3 ensures excellent debris pickup without clogging or losing power.

ET-1 Power Head with Brushroll Control

The included ET-1 motorized powerhead offers four manual height settings and a brushroll on/off switch. It cleans deep into carpet fibers, adapts to different pile heights, and can be switched off to safely vacuum hardwood or tile floors without scattering debris.

AIRBELT Bumper System

SEBO’s patented AIRBELT bumper protects walls and furniture while diffusing exhaust air quietly and cleanly for improved air quality.

S-Class Filtration System (Meets HEPA Standards)

The S-Class filtration system traps 99.97% of particles down to 0.3 microns. This hospital-grade system includes a multi-layer filter bag, pre-motor microfilter, and electrostatic exhaust filter—all sealed within the vacuum to prevent allergen leakage.

Variable Speed Suction Control on Handle

Adjust suction power easily from the handle with a simple slider control—perfect for switching between drapes, upholstery, and thick carpet without bending down to the canister.

Quiet Operation

Precision airflow design and insulated motor housing keep noise levels low, making it an excellent choice for households with pets, children, or noise sensitivity.

3.5-Liter Dust Bag with Hygienic Seal

The large filter bag holds more debris for fewer changes and includes a hygienic seal to trap dust upon removal—ideal for allergy-prone users.

Integrated Tools and 37-Foot Reach

Features a telescopic wand, 25-foot retractable cord, and onboard crevice tool, dusting brush, and upholstery nozzle—providing a generous cleaning radius in a compact, easy-to-store canister.

Engineered for Allergy Relief

The sealed S-Class filtration system locks in dust, pet dander, and allergens—ensuring cleaner floors and noticeably fresher indoor air.

German Build Quality

Built in Germany to exacting standards, the K3 Premium features high-impact ABS plastic, a reinforced hose, and a stainless steel wand—engineered to last 15–20 years with proper care.
