Perfect replacements for the G30
I wanted to replace the filters in my old G30 more frequently, as it's still running like a champ. I figured keeping up on it more often would help prolong its life expectancy. So far, so good. The less expensive replacement parts definitely help me not get upset every time I want to replace something. All parts from this pack fit perfectly, and the price is reasonable enough to avoid pushing replacements to the very last minute—at least it did for me, lol.

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.

Very great and durable option.
Style: for Saros 10R / Saros 20 / Qrevo CurvX
These parts are the perfect option when maintaining your robot vacuum. They fit the machine perfectly and are just as if not more durable than the company provided parts. Definitely recommended.
