With the growing popularity of smart home technology, smart home appliances like robotic sweepers have become a common sight in many households. But did you know that the world's first sweeper wasn’t even smart? It was a manual device that marked the beginning of the sweeping industry. What exactly is considered the milestone product in this evolution? Let’s take a closer look at the history of sweepers and how they’ve transformed over time.
**The Early Beginnings of Sweeping**
In 1898, John Thurman from St. Louis, USA, filed a patent for a carpet vacuum cleaner (US No. 634042), which is often regarded as the “ancestor†of modern sweepers. This early device had two possible versions: one used compressed air to blow dust into a container, making it more of a dust blower than a true vacuum, while the other involved offering a cleaning service for $4 per visit. However, this early model had significant drawbacks — the dust would often fall back onto furniture, making it ineffective for thorough cleaning.
**A Major Leap Forward**
By 1901, an English inventor named Hubert Booth improved the vacuum cleaner design. His version included a vacuum pump, dust bag, hoses, and various nozzle attachments. It featured an electric fan that created a strong suction force, drawing dust and dirt into the machine and filtering it through the dust bag. This innovation laid the foundation for the modern vacuum cleaner and marked a major step forward in household cleaning technology.
**The World’s First Sweeper Robot**
The first true robotic sweeper came much later — in 1996, when Swedish company Electrolux introduced the “Trilobite,†a pioneering robot designed to clean floors autonomously. While not fully intelligent by today’s standards, it could navigate under furniture and avoid obstacles using ultrasonic sensors. The second generation added infrared sensors, but lacked a downward-facing sensor, so it relied on magnetic strips or virtual walls to prevent falling down stairs. Despite its limitations, the Trilobite was a breakthrough in automated cleaning and was mass-produced in 2001, though it was quite expensive at the time.
**The Rise of the Three-Stage Cleaning System**
In September 2002, iRobot launched the Roomba series, which introduced a revolutionary “three-stage cleaning system.†This design combined a side brush, a roller brush, and a suction port, significantly improving cleaning efficiency. The V-shaped roller brush helped lift static dust from the floor, making it more effective than traditional vacuum cleaners.
**Intelligent and Functional Development Today**
Today, robotic sweepers are evolving rapidly, focusing on both intelligence and functionality. With advancements in AI and sensor technology, modern models offer features like remote control via mobile apps, scheduled cleaning, automatic recharging, and voice alerts. These innovations have made smart sweepers more affordable and practical for everyday use.
**Pusannik JOJO Mopping Machine (1299 yuan)**
While not a traditional robot, the Pusannik JOJO mopping machine uses a combination of dry and wet cleaning pads. It moves in straight lines for dry wiping and follows a Y-shaped path for wet mopping, effectively removing stubborn stains. Its key features include GPS-like indoor navigation, bionic design for better cleaning, and a highly sensitive physical sensor system for obstacle avoidance.
**Pusannik 790T (1699 yuan) and IMASS A3 (1999 yuan)**
These models are inspired by the three-stage cleaning system, featuring edge brushes, roller brushes, and suction ports. Both support remote control via mobile apps, scheduling, and automatic charging. The 790T uses bionic ultrasonic and infrared sensors for advanced navigation, while the IMASS A3 includes a wide-angle camera for remote monitoring and video calls.
