Abstract
A novel cleaning container is disclosed for backflushing and hence clean an espresso machine. The container may include a body having a top, an opposing bottom, and an interior cavity for holding water, detergent, and/or other cleaning fluid. A piston is slidably disposed within the interior cavity between up and down positions, wherein the piston and an opening of the body at the top define a variable volume for cleaning the machine. A spring is seated firmly within the body underneath the piston for biasing the piston to the up position. A stopper disposed about the top of the piston limits the motion of the piston at the top of the body. One or more grooves within the body are in fluid communication with one or more outlets to permit fluid to exit the body during cleaning. The body may be transparent or translucent.
