How Do Robot Vacuums Navigate? - Dreame Global

How do robot vacuums move across the floor vacuuming, cleaning, and sweeping? When they were first launched, robot vacuums used basic technology and would move haphazardly when cleaning. They were able to clean large areas but were inefficient as they keep cleaning the same places.

You can find more information on our web, so please take a look.

More developed models use an advanced robot vacuum navigation system, which is enabled by algorithms and sensors. The technology allows the vacuum to move in straight lines, covering all areas. The vacuum robot needs to map your home first to be able to clean effectively. It will then store this information and use it when vacuuming in the future.

What is Robot Vacuum Mapping?

Robot vacuum mapping is a process by which robot vacuums map your house during the initial cleaning. Mapping helps the robot understand how the house looks like, making it easier to clean all areas, and the majority of high-end models are capable of cleaning hard surfaces and carpets alike. Even in textures that seem similar, mapping helps it avoid the sections that it has already cleaned.

This map can be saved in a smartphone app using the map saving option, which is especially helpful for larger homes. You can also use the app to pick areas that you want the robot to clean if you prefer zone cleaning.
After buying the robot vacuum, stay home when it's cleaning for the first time and monitor the process. Since it's doesn't understand your house, it needs to learn the routes.

Whenever a robot vacuum follows the route, they eventually will have to dock to recharge, but how do robot vacuums find their base? After cleaning or when the robot has run out of charge, infrared signals show where the base is. The robot vacuum navigates to the base. After recharging, it continues to clean the home. Though the process may seem straightforward, there are many different methods that a device can use to map out the home.

The Main Types of Mapping Technology

Vacuums use different technologies to map a house, which may include the 4 following main mapping technologies discussed in this section.

Camera-based mapping

This technology uses a digital camera that maps by taking photos of landmarks around the house. While this technology maps well, it does not work in the dark. But some manufacturers are beginning to add a source of light on some of the devices.

Lidar-based mapping

Lidar is an invisible spinning laser that detects information. It collects data on the room's size and obstacles, such as legs at the laser level, but it starts by mapping the house, cleaning it systematically in straight lines instead of randomly.

Lidar technology is the most precise at mapping and has accurate navigation compared to the others.

Gyroscope or accelerometer mapping

Gyroscope and accelerometer sensors calculate the distance and direction of objects around the house.

The vacuums that use this technology are affordable. But it does not create a precise map and does not navigate as well as vacuum robots that use lidar and camera-based technologies.

Combined technologies

Some vacuum robots combine two or three mapping technologies. These technologies are used together with sensors and the robot vacuum cleaner algorithm to help the device navigate efficiently.

Sensors Help with Robot Vacuum Navigation

Robot vacuums use mapping to form route cleaning, and while they are moving, they use sensors to detect road conditions. Let&#;s take a look at cliff sensors, obstacle sensors, and other forms of tech that help these devices work.

Cliff sensors

All vacuum robots have cliff sensors as a safety requirement. Cliff sensors use infrared light, which is reflected from objects. The objects then send a signal back to the receiver in the vac.

If the vac does not receive any signal, the receiver detects no object and changes the path. This will prevent your vacuum from falling off the staircase.

Obstacle sensors

When cleaning your home, a vacuum will inevitably come across obstructions from furniture and other things that lie on the floor. Obstacle sensors, which are typically placed on a vacuum's bumpers, will guide it through the obstacles.

When the vacuum comes into contact with an object, the sensor will go off, forcing the vacuum to steer away from it.

Wall sensors

These sensors use infrared light to detect walls and then clean along the boundaries. The robot will do so effectively and without bumping the walls.

Wheel sensors

Light sensors count the wheel rotation to determine the distance it has covered. Although it was common to use these sensors when robot vacuums were new, only low-end models use them.

How Does Dreame Robot Vacuum Navigate Your Home?

The Dreame F9 combines the camera and gyroscope mapping technology to move around your home when cleaning. The device can quickly learn the surroundings that it needs to know for cleaning purposes. This vacuum can capture up to 30,000 data points in the blind of an eye, creating an internal memory of the home so that it misses nothing during cleanup. With automatic room recognition, the Dreame robot vacuum moves effortlessly from one room to the next to clean, knowing exactly where it is at all times.

Even after this robot vacuum maps out its path, it continues to calculate any changes in the path at a rate of 50 times in each second. This constant update of barriers gives it greater navigation skills to prevent damage and sense any fine particles that it needs to clean up.

Dreame F9 has 14 infrared sensors, the device uses 8 of those sensors to check for obstacles in its path to avoid collision. The other sensors are used to map out the direction that the vacuum goes as it transitions from hard floors to carpet or as it nears the steps. Still, that doesn&#;t mean that the Dreame F9 is ill-prepared for obstacles since it is programmed to cross anything up to 20 mm.

The upgrades in learning and exploration which is called pioneer 2.0 Visual Navigation System allow users to link up the Dreame app with their vacuum, giving the user the power to program wall barriers with ease. And the cleaning route can be further customized by using the app interface to choose which parts of the home are off-limits.

Though the app also gives the user control over where they want it to clean. This app is available in both the Google Play store and in the App Store (for Apple), so anyone should have the access to download it.

With all of this advanced technology, the Dreame robot vacuum can continue to clean the home for up to 150 minutes (2 hours and 30 minutes) before it needs to dock and charge. If it runs out of power, it will automatically go to the base station and recharge. The base acts as both a resting and charging station, but there&#;s no need to go plug it in or order it to go charge. Instead, the smart technology will signal to the vacuum to go charge to eliminate the risk of losing power while cleaning.

Nowadays, cleaning robots are intelligent devices that are welcomed in homes, offices, and shops. You might believe you are familiar with them, but they can still surprise you in unexpected ways. This article will offer you a guide on a seldom-noticed but highlighted feature in house cleaning, the mapping function.

 

Robot vacuum with mapping technology, as indicated by their name, are robotic vacuums that can map your house and design their cleaning routes. With a virtual map, they can even remember their locations in certain areas.

 

Follow us and see how these robot vacuums learn your house and why they are a must-have for anyone who wants clean home.

How Do Cleaning robot Vacuums Map Your House?

 

Cleaning robot vacuums with mapping technology learn your house by scanning and mapping the layout of your rooms. To achieve this, two elements are essential. Sensors and lasers are like the sense organs of a robot vacuum. They direct the vacuum to see the surrounding environment. A mapping technology gives robots the intelligence to process data collected.

 

Set our ECOVACS DEEBOT series with mapping features for example. They are equipped with self-developed TrueMapping Technology that can direct the robots to move around your rooms while automatically detecting and dodging obstacles. Powered by this technology, ECOVACS vacuum robots can not only design cleaning paths based on the condition of your floors, but also recognize dust, hair, and debris with precision while avoiding edges, furniture and walls.

 

TrueMapping technology is combined with a series of components like dToF laser sensors and Lidar. The dToF laser scanning mechanism is a recent update from laser scanning. It uses an amplifier to increase the signals, thus doubling the scanning range and achieving stable scanning. The technology allows robot vacuums to recognize obstacles down to 2mm, massively improving the accuracy of mapping.

 

 

 

With these advanced sensors and lasers, ECOVACS robot vacuums are able to navigate around your rooms quickly to collect the data, which will be subsequently used to generate a virtual 3D map of the designated area. These data will later be transferred to your mobile so that the layout of your rooms is visualized and you can better understand how your robot friends perform their cleaning tasks. With these virtual 3D maps, cleaning robots can understand their real-time locations so that they can clean more efficiently.

 

What Does This Mean for Cleaning?

 

A cleaning robot with mapping features cleans more efficiently and further releases your hands from house maintenance. In the past, householders may manually move robot vacuums to different areas after they finish a cleaning cycle. Robotic cleaners and mops with mapping technology like ECOVACS DEEBOT line of products can design cleaning paths based on the layout of your house. Directed by the virtual map, they know where to go and clean effectively along the designated route. You can simply send directions through your or give a voice command.

 

This mapping function is frequently recommended for houses with multiple floors. For instance, DEEBOT series of cleaning robots can save up to two maps. Therefore, a single robot can process the data from different floors and plan out the cleaning route accordingly.

 

There are extra benefits that are under the spotlight. A mapping robot vacuum can perform specialised tasks like spot cleaning and edge-to-edge cleaning. The inbuilt sensors like the cliff sensor enable them to detect edges and measure distances so that our robot vacuums can avoid crashes and falls in time. Besides, the advanced sensors and lasers make robots more sensitive to tiny trash like spots, dust, and animal fur.

 

What Are the Different Levels of Smartness in Robot Vacuum with Mapping?

 

Robot vacuums are designed as smart devices and they are growing more and more intelligent. Mapping technology is a such development. With this algorithm, robot vacuums can be programmed to clean specific rooms. But their intelligence is never limited to mapping.

 

A robot vacuum with mapping features can see and hear. They have sensors that navigate them through complex working environments. Those equipped with advanced features like voice control can understand your voice directions and perform the assigned tasks.
