Title: Terrible!
Review: This model cleans well and collects a lot of dirt and dust, but the filter becomes clogged after each pass. While it is easy to empty the canister, getting the clogged filter clean is another matter. You have to bang the filter against a hard surface to knock the small particles loose so you can clear the filter and continue cleaning. Perhaps it is the dusty atmosphere in Colorado, but this is a nightmare vacuum to maintain and use.
