Made in Germany by Sebo, Europe's number one rated upright, this unit has a 3 filter system: the dust bag is triple layered, followed by a microfilter to stop particles down to .3 microns and a final motor filter completes the job. Regular vacuum cleaners remove only large particles down to 50 microns and simply pass the smaller particles right through the collection bag and back into the room. Without an allergy type vac (or central vacuumming system), dust mites and small particles are shot out the motor's exhaust. The Sensation has a computer- controlled head adjustment that raises and lowers to any surface from deep pile carpets to smooth floors; it even folds flat to get under beds, etc. All the tools are built into the case, it even has a pullout extension hose and wand for using with the crevice and upholstery accessories.
Guaranteed for 3 years.
Note: when you run out of dust bags it might be time to check out your microfilter and see if it needs to be replaced as well.
