Blue Pearl Robot - anyone know anything about them?

Its not even close to pool noodle material. I forget the name of the poymer, but it is rock hard when dry and soft and holds about a gallon of water when it is wet. It does a great job of brushing the walls.

The best way I can describe the material is it feels like pipe insulation when wet. You know the black insulation material for water pipes? When dry, it is hard as a rock. It gives you the impression of a sponge in that it's hard when dry/soft when wet though. I believe the material is actually PVA, whatever that means.
