Good Value Replacement Kit for Eufy C20
This accessories kit for the Eufy C20 Omni Robot vacuum includes everything listed in the description. The 8 mop pads are consistent in size and shape. They aren’t quite as thick as the original pads that came with the unit, but they fit well and give me a good supply of clean replacements. With dogs in the house, my Eufy is running almost daily, so that’s a big plus.
I haven’t used the other components yet since I had just replaced the bag and cleaned the filters before ordering. I’ll update my review if anything doesn’t fit as expected. For now, I’m comfortable giving this 4 stars — and if 4.5 were an option, that’s what I’d choose. This seems like a solid budget-friendly alternative to the OEM Eufy replacement parts.

A Game Changer for Pet Hair Cleanup!
Color: Black, Size: L40 Ultra Gen 2, Color: Black, Size: L40 Ultra Gen 2
This robot vacuum and mop combo has been fabulous. We have a golden retriever that constantly keeps us on our toes with shedding and cleaning, but this has definitely helped cut down the time spent cleaning every day. The suction power is impressive, it does a great job on pet hair, and the mop feature is a huge bonus. I also love the self-emptying dock and app control — it makes everything so convenient. Definitely worth it for pet owners!

Pretty solid upgrade from my old robot vacuum
Color: White, Size: L40 Ultra Gen 2
I bought this robot vacuum to replace an older one I had, and after using it for about a month, I’d say it’s been working pretty well overall. When I first got it, one thing I noticed was that it’s a bit on the larger side, so it does take up some space. Setup was pretty simple though, and once it got going, it just kind of did its thing without me having to babysit it. The suction is definitely strong enough for everyday dust and pet hair. I’ve used it on both hard floors and carpet, and it handled both without any issues. The mopping feature is new to me since my old robot didn’t have it. I’d say the results are about what I expected, it’s great for maintaining daily cleanliness, but for tougher stains it’s still not quite the same as scrubbing by hand. For regular upkeep though, it does the job just fine. The corner cleaning has actually been a nice surprise. It will go under furniture and use the side brush to get dust out of corners, which used to be something I had to do myself. Now I barely have to think about it.
So far, both my family and I are pretty happy with it. We haven’t run into any major issues. It does a good job avoiding objects around the house, although there were a couple of times where its path looked a bit random to me. Still, most of the time it’s quietly doing its job and saving us a lot of time on cleaning.

Powerful and convenient
Color: Black, Size: L40 Ultra Gen 2
Really happy with this robot vacuum so far. The suction is strong and it picks up dust and pet hair easily. Mapping is accurate, and it cleans efficiently without missing spots.
The self-emptying dock is super convenient and saves a lot of time. Mopping works well for light cleaning too.Overall, a great upgrade and definitely worth it.
