Abstract
A vacuum trash collection vehicle includes a frame with facilities for debris collection mounted on the frame which include a debris canister. There is a cover for the canister and there is a vacuum fan in the cover. A debris collection hose is connected to the cover and is in communication with the vacuum fan whereby vacuum is applied to the hose. There is a boom for supporting the hose and a driver control for manipulating the hose for debris collection. The debris canister is pivotally mounted on the frame and there are side-by-side debris collection containers positioned within the canister. A deflector plate is mounted above the debris canister to direct debris passing from the hose and into the cover toward both of the side-by-side debris collection containers.
