Can I replace the battery in my Xiaomi Roborock vacuum myself?

Yes, you can. Flip the Roborock vacuum over, remove the screws (usually Torx T8 or Phillips), pop off the bottom plate, and unplug the old battery. The tricky part is the connectors — use a flathead screwdriver to gently pry loose a JST-style plug with a tiny latch, and mind the fragile ribbon cables. Get a new battery that matches your specific model from a reputable seller to avoid cheap knockoffs that can swell or fail.
