Vacuum cleaner pneumatically connected to a power tool, method for controlling operation parameters of such a vacuum cleaner and power tool for pneumatic connection to such a vacuum cleaner

A method for controlling operation parameters under which a vacuum cleaner is operated, wherein if it is turned on, the vacuum cleaner being adapted for pneumatic connection to a power tool generating dust during its operation, in order to draw at least part of the dust away from the tool into the vacuum cleaner, wherein said method includes the steps of

• receiving information regarding characteristics of the tool and/or its current use at the vacuum cleaner,
• processing the received information and calculating a correction signal for at least one of the vacuum cleaner's operation parameters at the vacuum cleaner based on the received information, and
• adjusting the at least one operation parameter based on the calculated correction signal.

An electric or pneumatic power tool that generates dust during its operation, comprising a dust extraction device adapted to be pneumatically connected to a vacuum cleaner in order to draw at least part of the dust away from the tool into the vacuum cleaner, wherein the tool has transmission mechanism for transmitting information regarding characteristics of the tool and/or its current use to the vacuum cleaner.
