Overall, the product does what it’s supposed to do. The post filter (the one that twists into the back of the stain) seems to work perfectly, but the cylindrical filter is another story. Works for the most part, but if you turn the vacuum at the wrong angle, the center filter just falls out, which is really irritating when you’re in the middle of vacuuming the couch.
I have the dyson cordless v8, the suction returned to my vacuum but the pre-filter does not properly seal. On the upside the filters did eliminate the odor problem. I wish it did it's job and stayed in play and created a good seal. I am extremely allergic to the fine dust around me and would not want the filters to do the opposite for me.
I liked the power to clean when I have it. So very frustrating how after 10-15 minutes at most NO power. Handy to get in and under places. But- where can I get a battery pack so I can vacuum my house in regular time. This is crazy to vacuum for such a short time and then charge it for an hour. This took me hours to clean my house.
