Fits Eufy Vaccum

Does fit my basic self emptying Eufy. Have to move it around a bit to get it to recognize the bag, but it does fit!

Doesn’t fit
Size: C10 / C20 Bags
Same exact things happens to me of this review — If you have an Omni C20, don't bother with these. They do not fit. The cardboard is too small and it keeps tripping the sensor that detects the bag when I put the cover back on. I've tried multiple bags in the set and they all do the same thing. Now to go find the place to report this listing for false advertising so maybe other people won't get scammed like me and others in the comments have.

Great
Size: 21 Pcs for eufy X10 Pro Omni
I’m so glad I purchased the BUXEBUX 21Pcs X10 Pro Omni replacement parts for my vacuum! The set is very complete and includes everything I need to keep my X10 Pro Omni running like new. Each piece fits perfectly, and installation was simple with no hassle. The brushes and filters are durable and high-quality, and I immediately noticed better suction and cleaner floors after replacing the old parts. What I really love is the value—getting a full 21-piece kit means I’m stocked up for future changes without needing to order again anytime soon. It gives me peace of mind knowing I can easily swap out parts and keep my vacuum working efficiently. If you own the X10 Pro Omni, this kit is a must-have. Excellent quality, great fit, and worth every penny!
