The Lefant Robotic Vacuum Cleaner M571 is a cordless vacuum cleaner equipped with a charger, making it convenient for use. This model is designed for smart home compatibility with Amazon Alexa, allowing for easy control and scheduling. 

Note: this item is new in box. I tested it and it turns on but will not hold a charge. Appears that it needs an internal battery replacement. Nice for someone who knows how to do repairs or needs replacement parts.
