ABSTRACT:
This invention relates to a roller for moving water on and simultaneously drying very large, flat hard surfaces such as tennis courts. The roller has an outer sleeve which is made from a foam whose compression load density and porosity values fall within critical ranges. The roller moves the water in the rolling direction as it simultaneously establishes a moving seal with the portion of the hard surface over which the roller rides.
