SEBO FELIX UPRIGHT The Sebo Felix comes in three different variations, 'Ice Blue', 'Classic' and 'Fun'. The only major difference between the three (besides color) are the telescopic handles for height adjustment that are available in the Fun and the Classic. Also the Ice Blue is the introductory machine in the line and doesn't offer the variable speed control for the brush. Also, the top of the line (the Felix Classic) comes with an additional floor brush, though you would probably do just fine using the regular floor setting on the powerbrush as well. We highly recommend all three for anyone with dogs or cats that shed frequently. We also highly recommend the Sebo Felix to people with allergies who really need a high level of filtration to remove as many allergens from the air as possible. All three models have S-Class HEPA filtration, which is very important when coming from a German manufactured machine. The United States doesn't enforce any type of regulation on what you can call HEPA, so many manufactures are bypassing the implied guidelines as to what level of filtration a HEPA filter should provide. In Germany there are strict standards, and you can rest assured that when you have S Class Hospital Grade HEPA filtration from a German machine, you are removing a tremendous amount of dust particles from your living space every time you vacuum.
