A vacuumcleaner

A vacuum cleaner for heavy duty use - The core idea is to reduce number of handling operations needed to empty the dustbin.
The upper part with electricity powered engine is mounted to a retractable stand and the lower part - the dustbin equipped with wheels.
To empty the dustbin unplug the tube and press down the lever with a foot. Both parts separate. The upper one stands on the floor steadily whereas the dustbin is movable.
To put vacuum cleaner together push the dustbin below the engine part and press down the other lever.
