    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!

    Perfect fit but originals last longer
    Size: Eufy A-21Packs
    With 4 cats and 2 dogs and using my Eufy RoboVac 11S Max twice a day until it dies, the brush and filters don't seem to last long. These replacement parts fit perfectly, but do not seem to have the same lifespan as the originals - would have to do the math to see if it would be worth buying original replacements, but that is probably case dependent. Overall happy, but took a star away for shorter wear life.
