On the TRAC and ECO versions of the E51, solution flow rate can be controlled from the multi-function display on the control panel.
Pressing the ‘+’ or ‘-’ buttons determines the amount of solution dispensed to the brush. Flow rate is clearly displayed by dedicated LEDs. When all the LEDs are lit, the E51 dispenses an impressive maximum flow rate of 5.3 litres/minute.
On the BASE M and TRAC M versions, solution flow rate can be controlled using a lever that acts as a tap.
