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.
