What Makes the ET-1 Power Head Important?
One of the main differences between the D4 Premium and simpler canister designs is its ET-1 electric power head. It combines powered brush agitation with several features intended to make carpet cleaning and maneuvering easier.
Four Brush-Height Settings
The ET-1 uses manual brush-height adjustment, allowing the operator to select an appropriate setting for the cleaning surface.
180° Steering
The power head provides 180-degree steering ability to help maneuver around furniture and through rooms.
Tool-Free Brush Roller Removal
SEBO designed the ET-1 so the brush roller can be removed without tools for maintenance and cleaning.
Automatic Obstruction Shut-Off
The ET-1 includes an automatic shut-off function when the brush roller encounters an obstruction.
Brush Warning Indicator
The power head provides warning indicators related to brush height and brush-roll conditions.
Dual-Control Handle

SEBO D4 Premium Filtration System
SEBO D4 Premium Filtration System
The D4 Premium uses a multi-stage filtration design consisting of a pre-motor filter, AeraPure filter bag, S-class exhaust microfilter and a sealed casing. This design is intended to help contain dust and debris as air moves through the machine.
Pre-Motor Filter
The pre-motor filter provides filtration before air reaches the suction motor.
AeraPure Filter Bag
The D4 uses a large 1.5-gallon AeraPure filter bag with a hygiene closure for disposal.
S-Class Exhaust Microfilter
The exhaust microfilter provides an additional filtration stage before air leaves the vacuum.

40-Foot Power Cord
The D4 Premium has a 40-foot power cord, helping reduce the number of outlet changes during larger cleaning sessions.
52-Foot Operating Range
SEBO lists a 52-foot operating range for the D4, making it suitable for cleaning larger areas without frequently moving the canister.
320° Hose Rotation
The tapered suction hose connects to the canister with a 320-degree rotating connection to improve movement and reduce hose twisting.
Rubber-Coated Wheels
The D4 uses four rubber-coated caster wheels mounted on bearings and steel axles for smooth movement across floor surfaces.
AIRBELT Bumper
The soft foam AIRBELT bumper surrounds the canister and is designed to help protect furniture, walls and the vacuum from scuffs.
Low Power-Head Profile
The ET-1 power head has a 3.5-inch horizontal cleaning profile, helping it reach underneath low furniture and beds.
