In a way, it makes sense, but you really don't think about it. But doctors agree, that with the smoke this bad outside, avoid vacuuming inside your house. The thought behind this is that it can stir up the smoke particles that have already settled in your carpet. Popping them back into the air and recirculating them inside your home and into your lungs. So if you see your little robot smoking ... it's not on fire, it just needs to be deactivated right now.
