Better than my new fancy robo
Great suction power. Doesn't get stuck often. I've had this vacuum for 5 years and it still works great. We got an AirRobo with a mop feature and demoted the Eufy to the basement. But, the eufy works way better and I frequently bring it upstairs to pre-clean before the AirRobo. Love this vacuum! Do you have a version with a mop?

The best little helper!
Size: eufy L60 SES (renewed)
I've never owned a robot vacuum prior to this, and was somewhat curious on how it would work, and what it would really do in my small home. I got the L60 refurbished unit, and it came in a brand new box and it looked brand new when I removed it from the packaging. I charged it up, setup the app and connected it to Wi-Fi, ran a cycle and it was all so easy. It mapped my home and it is was off! It does an absolutely fantastic job. I run it daily and can notice just how much cleaner my hardwood floors are. We have a cat who is intrigued by it, but it does a fantastic job of cleaning up the litter that is tracked from his litter box. That alone is a lifesaver. I will run it in the morning and at night in cats area to keep the hair and litter completely cleaned up. So far I've only had a few small issues where it got stuck, twice from items left out, and once from a dirty sensor. You really need to make sure you have things put away and have the areas picked up, especially of cat toys and shoe laces, and once in a while wipe the sensors off if they get really dusty. I highly recommend this, it truly has been a huge help just in daily pickup and keeping the house clean. Its absolutely worth the money.

Filter is too small for full coverage
Filters are not the correct size, too small. Not worth the risk. Brush arm bristles were also all bent up.

Filters are the wrong size for the Eufy C10 vacuum
The air filters are smaller than the stock air filter. They will probably work if they are stretched out a bit, but as delivered, are unacceptable. The roller and the sweeper are good. Poor filter fit. Original filter size: 1.75 inch by 3.65625 inch. The filters in this set are 1.25 inch by 3.5 inch. Too small.
