The advanced control of the Stick Vacuum Cleaner "Quick Clean Prof. T9621" monitors the system's performance with a precision of 8,000 times per second and then transfers the data in real time to the LED display.
The information displayed on the screen includes the battery level, dust density indicator, error message indicators, and suction level indicator (ECO - MID - MAX - AUTO).
In Auto Detection mode, the vacuum cleaner "takes over" the floor cleaning. Depending on the amount of dust, the suction power is adjusted for longer duration and optimal results.
