I just bought an upright Riccar vacuum pressure - the Radiance - and will be the best upright vacuum cleaner I've ever endured. It was an expensive purchase having said that i think it's worth every penny and i can't fault it. However, I recently met someone who bought a Riccar upright vacuum after back as well as they told me about issues they had after with it on damp carpet. Remove the dirt inner compartment. If you are using a bagless Baseballes cleaner, just dispose the bag and change it...
