The Sebo Automatic X4 vacuum cleaner is made in Germany and has a 10 year warranty and is a sturdy and lightweight upright vacuum cleaner. It has many features to enhance your cleaning needs, including belt protection and suction motor protection that are two features that extend the life of the vacuum. There is an automatic height adjustment feature that ensures optimal performance on both carpet and hard-floor surfaces. The low 5 ½ inch profile when you lower the handle flat, allows you to clean under beds and other furniture. There is a handy warning light that indicates when the brush roller should be replaced due to bristle wear or whether your brush height is set too high for optimal cleaning. There is also a Clog light or Bag Full indicator with Automatic Shut Off which prevents overheating and motor damage from lack of adequate airflow. The wand and hose are ideal for cleaning furniture and stairs and are very user-friendly. The number of electrical outlet changes needed during use is reduced by the 40 foot cord length. No tools are required to easily remove the brush roller for cleaning; and ensures consistently effective brush agitation of the carpet. The Sebo Automatic X4 uses a large 1.4 gallon, disposable filter bag.
