Lots of extras!
Size: 2+12+12+2 pack
The brushes are a bit flimsier than the original but otherwise fine. I needed it for the rectangular filters more than anything

EUFY 11S
Size: 2+8 pack
Used to replace the ones for my EUFY 11S vacuum. They fit just like the ones and got my vacuum back to cleaning really good. Didn’t realize how loud my vacuum had become until I replaced these parts.

Side brush screw PSA 🤪
Size: Eufy B-18Packs
Reviewing parts for Eufy L60
Review posted for some PSA
When you get the brush replacement this kit comes with a tiny screw driver DO NOT USE THAT TINY SCREWDRIVER TO UNDO YOUR SIDE BRUSH IT WILL STRIP THE OEM SCREW AND MAKE IT USELESS.
the screw driver included fits the screws that are about 2 mil wide the side brush screw is different. Grab a regular screw driver to undo a side brush.
The main rolling brush cover is different but the rubber part still hits the floor at proper height so I don’t see a big issue there.
When replacing the filter the filter cover was a little snug but I don’t see a big problem there just be aware to close the cover all the way but be careful not to push too hard so the plastic clips don’t break on the cover.
Don’t forget to wipe down all the seals when installing the filter to maintain the seal integrity to keep the suction at top intensity.
The dust bags seemed to be cut out with a stencil which gave the cardboard a better appearance than the oem cut out dust bags so that was interesting, dimensions were identical when comparing so I don’t anticipate any issues!
Over all I’m glad we have cheaper alternative replacement parts that can be used so thank you! ❤️

Great parts replacement kit for Eufy!
Size: Eufy B-18Packs, Size: Eufy B-18Packs
This kit has made it nice keeping up with our Eufy robot vacuum. All parts were free of defect and fit as it should. Instead of replacing individual piece by piece, I now just change all of the replacement parts at one time and it’s good to go for a while! Great value. Great quality. Will definitely be buying this kit again!
