The SEBO name is viewed as the best manufacturer of upright vacuum cleaners in Europe, and is legendary for its vacuums durability. The Sebo X-series upright vacuum cleaners are an overall best pick among uprights. Lighter than most, the X vacuum series rewards with excellent suction, for thick berber, cotton, or wool carpet that has dirt embedded deep into the carpet fibers, not just surface particles, suitable for pet hair and high traffic areas. The Sebo S-Class Filtration System guarantees that dirt is picked up and filtered through a 3-layer filter bag, electrostatic microfilter, and exhaust filter inside the Sebo vacuum cleaner. Any vacuum cleaners meeting the S-Class standards are equivalent to meeting HEPA requirements to filter out 99.97% of pollens, household dust, dust mites and other allergens as small as 0.3 micrometers in size. For particles 1 micrometer and larger, the filtration rate is 100%. The X series offers one of the most consumer friendly features on the market: the upright vacuums have an electronic sensor that automatically adjusts the height of the brush roll as needed. While we recommend using the floor brush for tile, wood, and vinyl, those who like quick pick ups of dirt will appreciate the auto height adjustment. Onboard tools include crevice tool, upholstery tool and small dusting brush. Their unique slim line design means the vacuum has the ability to bend at the handle 180
