Technology has made our life easier. Numerous inventions surround us, and we cannot imagine our lives without them. One such innovation is a Robo vacuum cleaner that can be a great addition to our household gadgets. We can have more leisure time while Robo vacuum cleaner does the floor cleaning.

We bring you a quick overview of the Robo Vacuum cleaners and towards the end we would also have a Price comparison for robot vacuum cleaners

Technology Behind Robo Vaccum Cleaners

The technology behind Robo Cleaners Robo vacuum cleaners intelligently sparkles your floor without bumping into furniture. Most of them are high-tech robots that can frame a detailed map of your home & efficiently plot the cleaning areas. They do not have cameras as eyes but use a wide range of sensors & artificial intelligence that make up their navigation system.

Sensor Mapping  

The sensor-based navigation system is an integral part of the Robo vacuum cleaner. They rely on these sensors to keep themselves safe from any trouble and detect the cleaning areas. The sensor navigation system varies in different models of Robo vacuums; for example, some advanced Robo cleaners use carpet detecting sensors. 

Cliff Sensors or Drop Detectors: All robot vacuums come with cliff sensors. These sensors prevent falling from stairs. They measure the distance between the robot base and the floor by bouncing infrared light off the floor. The robot vacuum is less likely to drop and damage with these detectors.

Bump Sensor: Bump sensors, also known as wall sensors, keep Robo vacuums from bumping into furniture and walls. They help to navigate along the walls. These sensors also help Robo vacuums to move room to room along the border.

Obstacle Sensors: Some Robo vacuums are equipped with excellent obstacle sensors that can detect even a tiny obstacle, such as shoes, toys, and even wires. They can also push themselves against a barrier such as curtains to sense the softness so that they can go through and continue cleaning.

Optical Sensor: These are very important sensors on the robot’s wheels. It uses light sensors to detect how many times the wheels have rotated. This tells the robot how far it has gone and when it has to return to its base for charging.

Dirt sensors: Help the robot vacuum sense dirtier spaces and clean them thoroughly by making multiple passes over an area.


Gyroscope Navigation

Gyroscopes are used in aircraft, but this technology is also used in Robo vaccum to bump into things and form a basic map of your home. It is a significantly low-cost technology that can do the job well.


SLAM stands for “Simultaneous Localization and Mapping.” IT is a technique to track the robot by visualization displaying using an app. Furthermore, you can also see where the robot has cleaned and map its path. This technology has a drawback, ‘ projection error.’ When this error occurs, the robot has difficulty understanding how far it is from the setpoint and runs into obstacles.


LIDAR  stands for “Light Detection and Ranging.” It is the newest and most innovative technology. It uses multiple lasers to illuminate objects in the room and map out space, including the distance between objects in the room. One potential issue with LIDAR is that it cannot see tiny things like wires and cables. 

Benefits of Robo Vacuum Cleaners

Some benefits of a robotic vacuum that could convince you to buy one for yourself are as follows:

  • Once you set up a robotic vacuum cleaner to clean the house, you can get more time to do other things you like.
  • Robo vacuum provides you with a much cleaner environment.
  • These vacuum cleaners are smart enough to detect any change in the surface and switch to cleaning modes accordingly.
  • Robo vacuums are much quieter than traditional vacuum cleaners.
  • Its circular-disc shape body helps to clean hard-to-reach areas.

Robo Vacuum Cleaners Buying Guide:

Here is a quick Robot vacuum cleaners buying guide for interested buyers:

  1. Survey your home and ascertain your cleaning needs. Consider whether you mostly have hard floors or carpet. If you have carpet, how thick is it? Think about pets as well — will the robot vacuum have to pick up kitty litter or thick fur? These are all important aspects to consider before you start shopping for a robot vacuum.
  2. Decide on your budget. As mentioned earlier, robot vacuums with the latest features can cost over $1,000. Cheaper models are available for around $200, but be prepared to lose some of the premium features, such as WiFi connectivity or the self-emptying dustbin.
  3. Do you want an app with that? Some robot vacuums can be connected with dedicated apps. Apps are useful for monitoring your robot vacuum and scheduling cleaning sessions. These can also help with mapping out your home and creating no-go zones.
  4. Robot vacuums use varying methods of navigation. If you invest in a lower-end robot vacuum, it will likely move sporadically and bounce off walls and obstructions in the process. Whereas, some medium and high-end models use lasers and optical sensors to guide them.
