Abstract
A dust extractor having an autostart functionality that includes: a motor and a fan to generate an air flow; an electric outlet connectable to a power tool; a control system; a user interface; and a current measuring unit to measure electric current of the outlet, wherein the control system is arranged to: measure a first representative current value of the electric outlet, associate the first representative current value with a first state of the power tool based on a first user input received via the user interface, determine a first threshold value from the first representative current value associated with the first state of the power tool, measure the electric current of the outlet, compare the measured electric current with the threshold value, and control the suction air flow of the dust extractor based on a result of the comparison.
