Scooba's Cleaning System
Scooba uses four cleaning methods in every pass.
1) Preps – Scooba picks up loose dirt and light debris from the floor.
You do not need to sweep the floor before using Scooba unless you
have large objects such as pebbles or large food particles on the floor.
2) Washes – Scooba continuously lays down a small amount of fresh
cleaning solution.
3) Scrubs – Scooba gently scrubs to clean spills and grime.
4) Dries – Scooba's squeegee vacuum picks up dirty water and debris,
leaving your floor clean and dry.
Scooba will clean until it has used all of the solution in the Clean tank,
approximately 45 minutes. At the end of a cleaning cycle, Scooba will enter
a drying mode.
Internal Drying Mode
At the end of the cleaning cycle, Scooba will enter a brief internal drying
mode to remove any liquid remaining on its brushes and inside its cleaning
mechanisms. During this time Scooba’s Clean light will blink blue.
TIP: If you wish to end a cleaning cycle early, iRobot recommends activating the
internal drying mode first:
• To start drying mode while the robot is cleaning, just press Clean.
• To start drying mode when Scooba is off, press Power & then press Clean twice.
