Great product for money but pay attn to your model filters are different on newer models.
Size: 20 PACK
The rollers work great and fit nicely into my Euphy which turned out I have a early version of which means none of the filters don’t fit my Euphy unfortunately and I hadn’t payed attention to the filters I was looking to get a 2 pack of rollers, the filters look nice though like they would make a great seal with the plastic and seal around them. I won’t buy them again for sure though for obvious reasons. Euphy is so much quieter then my second vacuum that’s a Roomba and she definitely gives her a run for her money and when it dies I will definitely be replacing her with a Euphy.
