### ⭐⭐⭐⭐⭐ Perfect Replacement – my Robovac is working again!
*by T***M on 13 June 2025*

I bought this for my Eufy RoboVac 30C, which had been out of action for three years. I finally looked into the 5 x 3 beep error and discovered it just needed a new battery! This LabTEC battery was a perfect match and has brought my RoboVac back to life. Installation was simple, and it’s running brilliantly again. Very happy with the result.
