Brush Motor ANTISPLASHING System
To prevent the brush from splashing water outside the work path, in case of particularly smooth oors, the
machine is equipped with an automatic brush motor system to reduce the power voltage in case of reduced
absorption. This system prevents the brush from reaching an excessive rotation speed, and additionally
reduced energy consumption of smooth oors.
The system operates as follows: if the brush motor current absorption is lower than the parameter “Reduced
brush consumption” (default: 9 Amp), the motor is powered at a voltage equal to the parameter “Brush
reduced voltage” (default: 20V) instead of the battery voltage. The transition time of the voltage value
applied is equal to the parameter “Brush voltage transition time” (default: 3 sec.).
