SEBO Airbelt K Volcano extended wand and hose

Clever on-board tool storage. Most vacuum cleaners in SEBO's collection features on-board tools, but they don't feature the same clever storage unit found on the K3.

Airbelt soft bumper. The SEBO K3 features an Airbelt bumper guard that helps protect your walls and furniture in case of hits and bumps. The bumper, which also serves as a protective layer around the vacuum cleaner's body, is made of two layers of soft foam encased in a highly durable covering. The bumper also works in two ways by helping disperse emitted air to keep the vacuum cleaner's noise level under control.

Rubber-coated wheels. The K3 features rubber-coated wheels that protect the surface of your floors. The wheels are safe for use on both hard floors and carpeted floors.

Telescopic tube. The vacuum cleaner is equipped with a well-designed telescopic tube that allows you to reach far while cleaning. The telescopic adjustment allows you to match the unit to your height and needs to make your cleaning tasks easier. The tube is also fitted with quick-release connections for easy, hassle-free operations.

Light indicators. The K3 takes the guesswork out of vacuum cleaning by offering you light indicators to alert you to any problems, such as a full bag, a clogged bag, or an obstruction in the brush.

ET-1 Powerhead. The K3 Onyx is equipped with a 12-inch ET-1 Power Head, a popular power head offered by SEBO. The power head is thorough, efficient, and even offers a 180-degree steering ability for maximum maneuverability while cleaning.

Parquet Brush. The K3 models are the main models that come with the well-designed parquet brush for hard floors.

Micro filters. The K3 Onyx uses the same three-step filtration process offered by other SEBO vacuum cleaners, but instead of the standard filters, the Onyx uses micro filters. This ensures that the K3 models are highly capable in clearing away even the smallest dust particles, making them an excellent choice for users suffering from or worried about asthma or allergies. The micro filters complete a tightly sealed filtration process that captures dust and keeps them inside the bag with no chance to escape.

Flat to The Floor 3 1/4" Low Profile

The power head's low profile makes cleaning under furniture and beds easy!

Mid-sized Canister Vacuum

The AIRBELT K3 and K2 are considered mid-size canister vacuums, which means they are smaller, more compact machines. They offer one mid-size and two full-size onboard attachments, a .8-gallon filter bag, an operating range of 32 feet, and the K-model canisters weigh about four pounds less than SEBO's D4-model canister.

Easy to Maneuver, Technically Advanced Power Head

The AIRBELT K3 comes standard with SEBO's ET-1 power head, which effectively cleans both carpets and hard floors. It is 12-inches wide and offers four-level manual brush height adjustment. Also, to clean delicate rugs and hard floors with straight-suction cleaning, the brush roller can be manually switched off. Its 180° steering ability provides amazing maneuverability. It also has easy brush removal, a handy clog removal door, and an orange warning light with automatic shut off for brush roller obstructions. The warning light also remains illuminated during use when brush height is set too high for optimal cleaning or when the brush roller should be replaced due to reaching maximum bristle wear.

Adjustable Suction Power Switch on Handle (Airbelt K3)

The vacuum's suction power can be adjusted from 0 to 1,250 watts by a slider switch conveniently located on the handle of the K3, providing convenient suction control for normal to more delicate cleaning tasks.

Combination of Three On-Board Tools (Airbelt K3)

The SEBO AIRBELT K models come standard with a crevice tool, dusting brush and upholstery nozzle. Also, many optional attachments are available that can be fitted to the telescopic tube or the hose handle.

Large Cleaning Range (Airbelt K3)

A 32-foot operating range, with a 20-foot cord, saves time because it minimizes the number of electrical outlets needed during use.

Tug & Retract Cord Rewinder (Airbelt K3)

The AIRBELT K models offer a "tug and retract" cord rewinder, instead of a control switch cord rewinder, which is offered on the AIRBELT D4 model.

Full Bag and Clog Indicator Light (Airbelt K3)

When a full bag, a clog in the airflow pathway, or an excessively dirty microfilter is detected, an orange warning light, next to the green "on light," on the canister body illuminates and an airflow bypass valve opens. This feature prevents overheating and motor damage from a lack of adequate airflow.
