40 - Recovery System
Functional Description
The recovery system removes the dirty water from the oor and pipes it to a recovery tank. When the
machine is running, the dirty water on the oor is collected by the squeegee blades and collected through the
slots in the same, piped through the vacuum hose and into the tank by the airow created by vacuum motor
(M2). The dirty water is piped into the recovery tank, while the airow continues to the vacuum fan.
A tank with a grid collects the largest debris going through the recovery tank hose.
The automatic oat in the vacuum grid stops vacuum system motor (M2) from collecting any liquids.
When the automatic oat closes and shuts down the vacuum system, the vacuum system motor noise will
increase and the oor will not be dried.

independently via the
Vacuum system button . The vacuum system is activated in full power or silent
mode depending on the last mode in use before the machine was switched o. This mode can be changed by
repeatedly pressing the
Vacuum system button . The various vacuum modes are also displayed on the
multifunction display.
When the recovery tank is full it can be emptied through the drain hose.
