The SEBO automatic X-Series vacuum cleaner is the most technically advanced upright vacuum cleaner in the world. Its ability to monitor the resistance of the brush roller against the floor allows it to raise or lower the power head automatically to the proper cleaning height. This guarantees optimal cleaning performance on all types of carpet and flooring and protects the floor from damage. The Intelligent Design of the SEBO automatic X ensures that the cleaning of hard floors (as well as carpets) is highly effective. The sealing strip on the bottom of the machine stops the kickback of dirt and channels the airflow through the remaining three sides, increasing the cleaning performance.
