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.

Excellent Deal
Size: Eufy A-21Packs
Great deal - pricing is fantastic making it easy to keep my little robo-vaccum running smoothly. The replacement parts are super easy to click into place - and having these multi packs will last a long time. Packaging is secure and the delivery was quick. The brush quality is excellent and function well with the exsisting parts already in place. These are not 'remakes' or 'versions' but an exact match to the originals. The replacement parts keep the same level of low noise and look intact. No guessing required. I'd recommend these for anyone with an Eufy RoboVac.
