********************
Robot vacuum cleaners have become very popular these days. The first ones came out in 2002, and more than 10 million have been sold. These vacuum cleaners move around the house cleaning the floor. Robot vacuum cleaners can be very helpful, but they can be dangerous, too. A 52-year-old woman in South Korea was sleeping on the floor, and the vacuum cleaner tried to suck up her hair. She woke up and called the fire department. They came and saved her. Luckily, she wasn’t hurt, but the message is clear: if you use a robot vacuum cleaner, don’t sleep on the floor!
