Autonomous Floor Cleaning Robot

In today’sfast-paced world, maintaining clean indoor environments efficiently and with minimal human effort has become essential. This paper presents the design and implementation of an Autonomous Floor Cleaning Robot that combines smart automation, obstacle detection, IoT-based remote control, and solar-powered energy efficiency. The robot is built using an ESP32 microcontroller, ultrasonic sensors for real-time obstacle avoidance, and motorized components for navigation and cleaning. A dual- mode system allows the robot to operate autonomously or be manually controlled via the Blynk mobile application. The cleaning mechanism includes a rotating mop and water spray system, enabling both dry and wet cleaning capabilities. A solar panel supplements power to extend operation and reduce dependency on external charging. The system is designed to be cost-effective, environmentally friendly, and suitable for domestic and small commercial applications. Experimental results demonstrate reliable obstacle detection, effective dust removal, and seamless remote control via IoT, making the robot a practical and scalable solution for modern floor cleaning challenges.
