Query: PB

It has rubbber wheels, bagless adn light weight. This little sweeper stands on it own in the corner. I like the swivel head and flexable head to get under cabinets. The only draw back that I have is that it does get warm quickly but other thatn that it does a great job picking up bird seed and dog hair from my lamanited floors.
