Nanotechnology and other technological advancements have contributed to the popularity of robotic vacuum cleaners. Many manufacturers have emerged in the market that offers a variety of robots to fit any wallet. Most of them have distinctive designs that fit into every nook but their operation mechanism may somehow vary. The main benefit of robotic vacuum cleaners is that they meticulously plot out their cleaning cycles with the use of smart mapping sensors and electronics.
This feature explains the technologies used in robot vacuum cleaners but before that, you need to understand what is robotic vacuum cleaners and their applications.
What is a robotic vacuum cleaner?
Robot vacuum cleaners are self-cleaning vacuum cleaners that work in the same way as a robot. New types of robotic vacuum cleaners are constantly being added to the world, with newer and better capabilities. Robot vacuum cleaners are mostly used to remove dust and small particles from floors in residential and commercial buildings.
Like a broom or conventional vacuum cleaners, the smart and compact robotic vacuum cleaners clean along walls and floors. The ability of the suction power and brushes assess the effectiveness of a robotic vacuum cleaner. Robotic vacuum cleaners, unlike traditional vacuum cleaners, may take more time to clean a certain area. Because they are largely battery-powered, you may need to recharge them if you plan to clean a large area.
The best robotic vacuum cleaners are able to clean even sharp corners while some may also perform the task of mopping the floor. This is done by spraying water through a fine nozzle.
Technologies used in robotic vacuum cleaners
Several components, which work with a battery, motor, and electrical system, are included in the robot vacuum cleaners. The technology used in these cleaners is quite conventional and minimalist.
- Battery and Motor
A battery is used to generate power for cleaning and dust release. The battery capacity of basic models of robotic vacuum cleaners is 12v and 3-5 Ah. Both rechargeable and detachable Li-ion batteries work fine with these cleaners. The main work of rotation is done by drive motors (which are coupled with gears) that are synchronized in nature to allow seamless performance.
- Sensors and Electronics
The concept of detecting dust particles and cleaning is performed by a couple of sensors. In some cases, multiple sensors may be deployed for the purpose. Obstacle sensors are also used in most cleaners to detect obstacles in a certain room.
It’s worth noting that robotic vacuum cleaners don’t look at the floor surface with the help of cameras. Different types of sensors such as cliff sensors, bump sensors, wall sensors, and optical technology are used to analyze and quantify the surface and objects around them.
For mapping and navigation, usually, radio technology and antennas are used in the circuitry that can comfortably map the room needed for cleaning. The antennas offer signals that can guide the cleaners to perform tasks in a specified area or move them near the main pod or docking station or charger chamber.
- Dust cleaning system
A brushing system (combination of both hard and soft brushes) is commonly used in robotic vacuum cleaners that can easily collect dust particles and empty those into the vacuum chamber. Both rolling and spring brushes are deployed in robotic cleaners. These brushes work in tandem, which brings the dust towards the vacuum system. Ball bearings are coupled with brushes that allow a continuous and flawless cleaning process.
After cleaning, you will need to empty the removable compartment where all dust is accumulated. It can be done through automation if the cleaner has the ability.
