Since last year, finally I've decided to buy the New pporo with orange color. I'm not sure whether it is working properly or not. after searching the review, I finally bought it and now I'm satisfing on it. When I used first time, it's bit a choky to move. because of couldn't vacuum up even front of hair and hit many time to the furniture however now I'm very easy living and get used. I handle over to Pporo for all vacuum up so I can do other things to do. If it's not clean up properly, I used the SSW mode. even if not clean up the corner, I used the Zzaloo. I will use a couple of years more and then will buy new model at that time. thanks.
