I bought it one and half month ago because my old Dyson cordless vacuum dies after less than 5 min working.  Some of my friends using LG A9 recommended buying LG.  I am satisfied with A9 with mop.  It is much quieter than Dyson, it has two batteries, and mine has a mop to clean my wood floor easily and easy to handle all accessories in one place. I am happy whenever I use it.
