For the maintenance
Sponge your court after the rain has passed and optimize your playing time by reducing your waiting time from 1/2 hour to 1 hour.
The Water Roller allows you to soak up a persistent puddle on the surface of your court. Only the humidity on the floor evaporates.
The Universal Absorbing Roller Special allows to soak up a larger quantity of water which it collects in its tank. This avoids having to go back and forth over the puddle several times, as it is the case with the Water Roller.
