Does this robot vacuum empty itself?
Models with a self-emptying dock vacuum their bin into a larger bag automatically, so you only empty it every few weeks. Check the “self-emptying” spec above.
Can it avoid obstacles and pet messes?
Robots with AI camera or reactive obstacle avoidance steer around cables, shoes and pet waste. LiDAR handles mapping; a camera adds object recognition.
How loud is it?
Most robot vacuums run between 55–70 dB — about as loud as a normal conversation. See the noise level spec for this model.
Does it work on both carpet and hard floors?
Yes. It auto-adjusts suction on carpet, and models with a liftable mop raise the pads to avoid soaking rugs.
