If you're looking for a way to tackle the toughest cleaning jobs, the Boost mode on your VK7 is just what you need. By pressing and holding down the Boost button, you activate the front sealing lip of the electric brush and temporarily set the suction power to its maximum setting. This allows you to easily pick up larger debris and particles that might be difficult to clean otherwise.
And with the flashing arcs on the power indicator, you can be sure when it is activated.
