In recent years, the concept of smart homes has gained widespread popularity, leading to an increase in demand for smart home appliances such as robotic sweepers. While today’s robotic vacuums are highly advanced, the first sweeper was far from being intelligent and required manual operation. What exactly was the milestone in the evolution of sweeping devices? Let’s take a look at the history of sweepers. **The Origins of Sweeping Devices** The earliest form of a sweeper can be traced back to 1898 when John Thurman from St. Louis, USA, filed a patent for a carpet vacuum cleaner (US No. 634042). This device is considered the ancestor of modern sweepers. There were two possible versions of this early model: one used compressed air to blow dust into a container, making it more of a dust blower than a true vacuum; the other involved offering a cleaning service for $4 per visit rather than selling the device itself. However, this early version had a major flaw — the dust would often fall back onto furniture, failing to fully clean the area. **The Evolution of Vacuum Cleaners** By 1901, a significant improvement came from England with the invention of the vacuum cleaner by Booth. This model featured a vacuum pump, dust bag, hose, and various nozzles. It included an electric fan that created a strong suction, drawing in dirt and dust through airflow. The dust was then trapped in the bag, while the purified air was released back into the room, helping to cool the motor and improve air quality. **The First Robotic Sweeper** The world's first robotic sweeper was the “Trilobite,” developed by Electrolux in Sweden in 1996. Although it was considered a precursor to modern smart sweepers, it wasn’t fully autonomous. Standing only 13 cm tall, it could easily move under tables and beds. It used ultrasonic sensors for obstacle detection and mapping, but early models struggled with navigation. Later versions added infrared sensors, though they still lacked downward detection, requiring magnetic strips or virtual walls to prevent falling down stairs. The Trilobite could run for up to 60 minutes on a single charge and offered three cleaning modes: normal, fast, and spot cleaning. **The Three-Stage Cleaning System** In 2002, iRobot launched the Roomba series, which introduced a revolutionary "three-stage cleaning system." This design combined a side brush, a roller, and a vacuum suction port, allowing for more effective cleaning of static dust and debris. Compared to earlier two-stage systems, this innovation significantly improved performance, making it a standard in many modern robotic sweepers. **Intelligent and Functional Development** Today, the robotic sweeper market continues to evolve rapidly. With increasing consumer demand for smart, functional, and affordable products, manufacturers have focused on improving user experience through enhanced intelligence and additional features. Many models now offer great value, with prices ranging between $1,000 and $2,000, making them more accessible and practical for everyday use. **Pusannik JOJO Mopping Machine (1299 yuan)** The Pusannik JOJO mopping machine isn’t a traditional robotic sweeper, but it offers a unique approach to cleaning. It uses a combination of dry and wet pads to move in straight lines, effectively removing dirt, dust, and hair. The water pad follows a Y-shaped path with a damp cloth, enabling deep cleaning of stubborn stains. Key features include GPS-like indoor positioning technology, bionic design that mimics human movement for better cleaning, and a highly sensitive physical sensor system that detects obstacles more accurately than infrared sensors. **Pusannik 790T (1699 yuan) and IMASS A3 (1999 yuan)** Both the Pusannik 790T and IMASS A3 are inspired by the three-stage cleaning system, using a side brush, roller, and suction port. They support remote control via mobile apps, scheduled cleaning, and automatic recharging. The 790T includes bionic ultrasonic and infrared sensors, while the IMASS A3 features a wide-angle camera for remote visual control, video calls, and even smart home security monitoring. These advancements highlight how far robotic sweepers have come, blending smart technology with practical functionality to meet the needs of modern households.
