LG HOM-BOT Square Robotic Vacuum Cleaner is a low-noise, ultra-thin, intelligent cleaner that vacuums and mops at the same time. Powered by strong suction technology and ultrasonic sensors, it picks up every speck of dust, pet hair and dirt, leaving your house flawlessly clean.
What makes it smart is the use of dual cameras to scan the floor as well as the ceiling to avoid any obstacles and bumps. It memorises the layout of your house using its self-learning feature.
Other smart features include scheduled cleaning, spot cleaning and mopping, and self-diagnosis for smart repairs and voice alerts. Priced at $1499 (at the time of publishing this article), this robotic vacuum cleaner is one of the most expensive smart cleaners in the world.
