1. What is the purpose of an automatic vacuum cleaner?
The purpose of an automatic vacuum cleaner is to assist human with floor cleaning, furniture, rugs, and carpets by suction. It reduces the need for manual labor and unattended operations through automatic control systems. The vacuum cleaner helps in maintaining a clean environment, reducing health risks associated with dust and allergens. It is particularly useful in large areas, such as colleges, where social distancing is necessary. The integration of digital technology, like Arduino, allows for efficient cleaning by programming the vacuum cleaner to cover specific areas and avoid obstacles.

2. What is the working principle of Bluetooth module?
The Bluetooth module operates by sending an ultrasonic pulse at 40kHz, which travels through the air and bounces back when it encounters an obstacle. By calculating the travel time and the speed of sound, the distance to the obstacle can be determined. This technology is independent of light, smoke, dust, and software requirements. It is commonly used in applications such as ultrasonic sensors and can be programmed using the Arduino IDE. The module is particularly useful in autonomous systems, like the RC car with a vacuum cleaner, where it helps avoid collisions with obstacles by measuring the distance. The vacuum cleaner itself is designed with a CPU fan and a pipe attached to the mouth of the bottle, and the entire system is powered by batteries. This technology offers a more efficient and convenient alternative to traditional vacuum cleaners, which can be bulky and require significant manpower for operation.

3. How does the smart vacuum robot navigate and detect obstacles?
The smart vacuum robot navigates and detects obstacles using three ultra-sonic sensors. When the robot is turned on, the sensors check for obstacles on its path. If an obstacle is detected, the robot stops for a few seconds and changes its direction according to the program. The robot continues its cleaning process after checking for obstacles. Additionally, the robot's battery level is monitored, and if it falls below 40%, the user is notified through the application. The communication between the software and hardware components is illustrated in Fig. 9, showing the flow of information between the different components of the smart vacuum robot.

4. How does the developed robot navigate and clean efficiently?
The developed robot is fully operational and navigates according to logic. It operates to clean dry dust particles with high efficiency. Being a wireless device, it can cover large areas. The robot requires minimal human interaction, reducing human work. It can be upgraded with functionalities like dust detection, self-charging, self-dust disposal, and scheduling. The robot's shape is well-suited for cleaning tasks, especially along ball, legs, and corners. The ultrasonic sensor identifies obstacles, and the robot's shape, sensor system, and algorithm work together to make cleaning in unknown and unstructured environments feasible.
