Abstract - Cleaning a large indoor area like a warehouse,
simple gravity-assisted pathway. The system integrates a belt–pulley drivetrain, powered by a compact DC motor, enabling simultaneous propulsion and cleaning without complex electronics.
commercial hall, and institutional facilities is time-consuming, expensive to do manually, and would require industrial cleaners and robotized cleaners are usually very expensive, difficult to use, and inappropriate in small and medium-sized businesses. The conceptual design of an automated mechanical cleaning and waste collection robot, which has named Brush Bot, optimized to work in smooth-surfaced environments. The Brush Bot, unlike standard vacuum based cleaners, employs the use of a drum brush with a secondary bristle system, but operated by a belt-transmission with a small DC motor. Development design is aimed at achieving low-cost features, lightweight body, operating with low energy consumption, and low electronic dependency to enhance affordability, durability, and sustainability. The resultant system will be capable of providing efficient dry debris collection at minimal noise with long-run time, making it an intermediate between small domestic robots and large industrial sweepers. This paper offers a viable design route to a sustainable, low-cost, and scalable cleaning robot that lies between manual sweeping, which is labor-intensive, and the costly robots.
The focus of this study is on engineering design and analysis, including drivetrain calculations, torque and power estimation, energy consumption analysis, and finite element simulations for structural integrity and brush–floor interaction. The conceptual framework aims to achieve a balance of cost-effectiveness, energy efficiency, durability, and sustainability, making it a practical alternative for SMEs, institutions, and public spaces.
2. LITERTATURE REVIEW Automated floor-cleaning technologies have evolved significantly over the last two decades, ranging from smallscale household robotic vacuums to large industrial sweepers. The literature broadly categorizes these solutions into domestic robotic cleaners, industrial/commercial cleaning machines, and research prototypes.
Key Words: Cleaning robot, automated sweeping, brush mechanism, sustainable design, floor-cleaning automation.
Household robots such as the iRobot Roomba have gained popularity for residential use due to their compact size, autonomous navigation, and ease of operation. These robots typically rely on suction motors coupled with small rotating brushes to lift debris from the floor surface. While effective for fine dust and lightweight particles, studies such Prabakaran, S [1] and Parikh & Patel [2] emphasize that suction-based systems demand high power input, generate elevated noise levels (>65 dB), and require frequent filter maintenance.
1. INTRODUCTION Cleanliness and hygiene in industrial, commercial, and institutional environments are essential for operational efficiency, safety, and overall well-being. Facilities such as warehouses, shopping malls, hospitals, schools, and office complexes require frequent floor cleaning to control dust, debris, and waste. Traditionally, this task is performed manually by cleaning staff using brooms or mops, which is labour-intensive, ergonomically challenging, timeconsuming, and inconsistent in quality. The reliance on human effort not only increases operating costs but also exposes workers to repetitive strain and health risks.
Industrial cleaning machines, [3] and manufacturers like Tennant Company [4][6], offer high throughput and efficiency. These machines often combine rotating brushes, vacuum suction, and large debris bins, enabling them to clean expansive areas quickly. However, they are characterized by high capital cost, large physical footprint, and significant maintenance requirements.
To address this gap, this research proposes the design of a mechanically driven automated floor-cleaning robot, termed Brush Bot, specifically optimized for smooth indoor surfaces. Instead of suction motors, the Brush Bot uses a rotating cylindrical brush combined with a bristle-assisted sweeping mechanism to agitate and collect debris into a bin through a
