The Saros 10R packs a 6,400mAh battery and charges faster than you might expect.

How Long to Charge?

About 2.5 hours for a full charge. That's way better than older Roborock models that sat on the dock for 5 hours.

Even better: the dock is smart about it. If the robot runs out of juice mid-clean, it figures out exactly how much charge it needs to finish the job, tops up to that level, and gets back to work. No waiting around for a full charge just to vacuum one more room.

How Long Does It Run?

Depends on what it's doing, but here's what testing showed:

• After 80 minutes of vacuuming and mopping, it still had 57% battery left
• It covers about 1,389 square feet per charge, which beats the average of 1,020 sq ft
• Roborock says it's good for homes up to 2,000 square feet

What If Your Home Is Bigger?

The robot handles it automatically. Battery running low? It heads back to the dock, charges up, and picks up exactly where it left off. You don't have to babysit it or restart cleaning sessions.

Why Does It Last So Long?

Part of it is the efficient navigation. The StarSight system plans smart routes instead of bouncing around randomly. Less wasted movement means the battery goes further.

Compared to Older Models

The 6,400mAh battery is bigger than the 5,200mAh in the Qrevo Slim. Both the Saros 10R and regular Saros 10 perform similarly here, and both beat most competitors on battery efficiency.
