If you want your vacuum to work its best, you need a clean filter.
I admit that I blew through my first belt in 3 days as I was learning how to use a new vacuum. I learned that the vacuum needs to be in the upright position and running before you switch from floor mode to brush roll. This allows the belt to move to the right position. If you try to switch to brush roll mode while the vacuum is not in the upright position, it's harder for the belt to adjust and it will slip. I ordered more belts to have on hand but I have now vacuumed for a whole month without ruining another one!
These bags are great and much less likely to tear than paper bags.
Did a bunch of research for a vac like this. Finally came across Prolux. America made is big for us. Liked the features Titan has. We are very pleased with this machine.
