Allergies are commonplace in our Pacific Northwest. Dust/pollen removal in my busy dental office in hard-to-reach places, high horizontal hard surfaces is a recurring problem/task. Cordless, manoeuvrable, with good suction power for dust removal, this vacuum cleaner has always been a good choice. Practically without a bag. It is not used on our carpets, but most of our floor coverings have a hard surface. The only reason it hasn't been rated 5 stars yet is that 1 month of ownership hasn't given us enough time to determine durability.
