Q: Can it automatically return to the dock for charging?
A: Yes. When the battery is low, the robotic vacuum cleaner will dock itself, charge automatically, and then return to the original place to continue cleaning.
Q: Will it be able to climb onto area rug in our carpeted living room?
A: Yes. The E4 can be used on carpets, tile, laminated, and hardwood floors. When it walks on the carpet, the suction will increase up to 2000pa to take away the dust on it.
