Bough this unit to replace a Dyson that died out after just a few years and multiple batteries. This unit comes with 2 batteries already and a dual rotating mop attachment.  The vacuum works great 5 stars for sure, long life, light, easy set up and maintenance.  However, the mop did not spray any water.  I got a replacement under warranty, and it too does not spray the water out.  I'm have to wonder what I may be doing wrong but there is nothing to the directions that says otherwise.  Maybe someone has had this issue and knows how to get it to work, but I can't find much online.
