I teach piano and keep my beautiful red Pet Ergorapido at the ready in my studio.  The children are always tracking in mud, leaves, etc from the outside.   I also have a little chihuahua who does his part to leave tracks.  And the icing on the cake: my Pet Ergorapido is the only vacuum I have ever owned that is able to vacuum UNDER the 
pedals of the piano!!!!!  Love my little friend!!!!!!❤️
