it works on average 7/10. sometimes when there's hair tangled up inside the bin, then no matter how many times you try, it can't empty the bin and needs to be manually emptied. overall though, i don't think i can live without it once you own one! 

biggest complaint though, it's impossible to purchase dust bag. i've been searching for it for months and months but it's been out of stock and there's no estimate when it will become available. it seems like it's available to purchase in south korea but not in us. i hope samsung can at least update their customers when and whether it will ever be available since it's useless without it.
