The present invention is directed to a blowervac device having a grill (18) that requires to distinct steps in securing the grill (18) over a fan (24) to activate a safety switch (60) allowing power to the motor. The grill (18) has an outer ring (42) and a rotatable inner cover (44). The first step is simply to secure the grill (18) over the fan (24). The second step requires the cover (44) to be rotated, which activates an actuator (62) for the safety switch (60), allowing power to be delivered to the motor and operation of the device. This two-step process reduces the likelihood if inadvertent operation of the device and reduces the chances of injury
