Over time, you may notice that the battery holds less charge, requires more frequent recharging, or a decrease in cleaning performance. Use this guide to help replace your battery and restore your Lefant M210 robot vacuum to like-new performance.
Before you begin this repair, turn off the vacuum.

Great guide! Any knowledge on how or why mine beeps twice even when it is on the ground?
Thank you for the helpful guide, however, after replacing my battery, it definitely has a much shorter lifespan, and it is unable to find the charger before it dies.
I thought it was because I needed a new battery. My stops about 1min after start. When I put it back to the charger it indicates battery charged by showing the blue light. Still after 1 min of operation it dies. That's the reason why i want to replace the battery. Is that what yours is doing too even after replacing the battery?

Thanks for the guide.
As for those that stumble upon this, mind that ******if you only want to access the battery, steps 10 to 16 are the only on you need.
