I am a Dealer and one who has serviced and repaired vacuums for 19 years. The Auto X4 shines like no other vacuum does except for the other SEBO Models. I show my customers how well it is put together and how easy it moves from 1 level of bare floor onto carpet and how once they have seen how it works for them in the shop it is sold.There is not any other brand that even comes close to SEBO. In this business ,"Cheap Vacuums" are NOT Cheap and "Expensive vacuums " are not expensive ! There is a brief period where the customer learns how the Vacuum works and then...Peace! I hardly ever hear from them except for timely filter and brush changes.
