This attaches to the flexible hose 
on your vacuum cleaner (diameter 
32 or 36 mm) to become an extra 
container with a volume of about 
20 lt. It quickly gets rid of ash, 
charcoal, pieces of unburned wood, 
soil, rubble and even liquids as 
long as they are not inflammable;
it clears blocked washbasins and 
vacuums up accidentally spilt 
liquids.
