Abstract
A vacuum unit used to vacuum lawn debris includes a vacuum unit body having at least first and second inlet openings and at least one flap that can be adjusted to selectively cover and open the second opening. The vacuum unit body includes a flap adjustment member that is located within the second opening and that includes a contact surface that contacts the flap. Preferably, the flap adjustment member has one end that is adapted to receive a vacuum hose. The flap adjustment member can be placed into a first position where it causes the flap to open the second opening and a second position where it permits the flap to cover the second opening. The vacuum hose has a handle that can be attached to the vacuum unit handle permitting the vacuum hose to remain permanently attached to the vacuum unit even when the vacuum hose is not being used.
