A Comparison of the SEBO Airbelt K3 Models. All of the K3 models are the same body style, but they have different attachments for carpeting.
Similarities:
All of the K3 models are completely sealed with SEBO's S class filtration which is hospital grade filtration. They all have 2 filters which you change, (not clean!) regularly. Cleaning attachments included are stored on the body of the canister and attached to the wand. All of these models have a 360 bumper guard.
9679AM (blue)- air driven canister. This has 1 dual function head to clean either hard surface flooring or low pile / delicate carpeting as it does not have a spinning brush roll. These dual function attachments are nice as they allow you to toggle between carpeting and hard flooring with one head.
9687AM (red)- electric carpeting power head with 4 height settings for all pile carpeting. Separate hard flooring attachment for any and all hard flooring. You can clean all mixed flooring with this machine.
9688AM(Onyx)- electric carpeting power head with 4 height settings for all pile carpeting. Separate hard flooring attachment for any and all hard flooring. You can clean all mixed flooring with ease. As this model is in the Onyx collection it comes with SEBO's Value Pack. This includes a 10/10/7 warranty, a 9 foot hose extension, a tool adaptor, a handheld turbo attachment to clean carpeted stairs, upholstered surfaces, or any pet hair (great in the cars!), a 24" flexible crevice attachment, and a upgraded parquet hard flooring attachment.
