### ⭐⭐⭐⭐⭐ Vacuum like new!
*by J***R on July 28, 2024*

After about two years, my Eufy robotic vacuum stopped working. The charging light was red and stayed on. The vacuum emitted a constant beeping noise. None of the troubleshooting solutions was applicable. I cleaned it well and replaced all parts. It still did not work. I purchased this replacement battery. It was easy to install. The vacuum works like new.
