Wheelie bins aren’t that easy to move about when full of refuse.
Today’s invention is an extra set of wheels for such bins.
These would be mounted on a common axle and driven by two small independent electric motors, mounted to a frame.
The bin owner would attach two swingarms to the normal bin wheel axles, place the extra wheels at the front and rock the bin back through a few degress so that the front edge was on the frame, slightly clear of the ground.
The motors would be activated remotely so that the bin could be directed across a garden and onto the pavement for collection (a little like the latest golf bag trolleys).
Once out there, the wheel unit would be removed and safely stored until the next bin collection.
