I love mine! I have a 3 storey house and hated hoovering the stairs. I can lift this with one finger and it has the best suction I have ever come across! Being cordless too is a major bonus. I would never go back to a normal cleaner.
I have both. I bought the airam from QVC and then the multi when the gtech website were offering £10 off and free postage. I like them both very much. The offer from the gtech website for the multi included a free extender.
