Roomba is becoming a part of many houses day by day due to its facility to clean surfaces. Many people say that it is like a part of a family. Roomba is doing a good job for any home. It’s contributing to the cleaning process which is considered as one of the hard jobs to do. Specifically under the bed and corners. This machine is amazing in its qualities.
However, it is always interesting to know about the machines more and more. There are two main reasons one it removes your curiosity about the working procedure and it helps you to figure out the problem if the machine stops working.
The same is true for the Roomba, this automatic cleaning machine is interesting to understand. How it works what are the different symbols on the machine. How its sensor works and most importantly the different indicators for the Roomba to know that it is time to stop cleaning.
This last interesting fact about how does Roomba know to stop cleaning is the topic of the article. In the following section, we will try to know about the indicators that let the Roomba know to stop cleaning.
Different Indicators for Roomba to Stop Cleaning
There are many indicators for Roomba to stop cleaning. Few are independent of the factor that if the cleaning process is complete or not and others depends upon completing the cleaning process. Following are both types of indicators.
Battery Low
This indicator stops the Roomba from cleaning. It is one of the top priority symbols. If the battery is low irrespective of the level or completion of cleaning the Roomba will stop working. You have to charge to restart it and complete the remaining work. This is so understandable, there is no physical solution that the Roomba can work without a battery. Every device needs the energy to work. In the case of the Roomba, the energy is provided by the battery. So, you cannot do a lot with this indicator. You have to recharge your battery.
Full Bin Indicator
Another indicator with a high priority and independent of the cleaning process. It doesn’t matter if the cleaning has been finished or not the full bin indicator will stop the Roomba unless you take it out and empty it then put it back to restart the Roomba. It is a sensible approach as well what is the purpose of cleaning if you don’t have an empty been to store the garbage.
That is why it is always recommended to empty the bin after each cleaning so that it must be ready for the next time. Or another option is that clean before you start a Roomba it is not as recommended as the first one because in this case dirt will stay longer in your Roomba. So, the full bin indicator can also stop the Roomba from cleaning.
Front and Bumper Sensors
The front sensor is located at the top of the Roomba. It is an infrared sensor and helps the Roomba to detect the walls. Bumper sensors beneath the Roomba help o recognize the bumps. Based on these indicators. Roomba is not only able to detect the dirt but also helps Rommab to measure the dimensions of the room. The internal system of the Roomba can then analyse the time required to complete the cleaning process of the room. In this way, Roomba can be sure about the cleaning process and hence stop cleaning once the time is over.
This is how smartly the Roomba works with the sensors, The sensors guide the Roomba on how to work and based on this exact information. Based on these, Roombas are successfully cleaning the rooms for many years.
Cliff Sensors
At the downside of the Roomba, there are cliff sensors. They are also infrared-based sensors. They can figure out the steep area. That is a point where the Roomba will take a turn and return. This is a situation it will find any obstacle like a table or some other things. It will feel like being in a tangle and hence will stop working and only start again until you help it out.
This is a safety feature for a Roomba, Roomba may get confused about being at a place it does not understand. So rather waste the battery or avoid any damage like hit a wall or something else to avoid the tangle Roomb prefer to stop. This is somehow a genius idea by the manufacturer to help the /Roomba in complex situations.
Dirt Sensors
Dirt sensors allow the Roomba to estimate the level of dirt in the room as well as on particular areas. It is quite obvious that more dirty area needs more time to clean. With the above-mentioned sensors and combined with the dirt sensors the Roomba can estimate the better time to clean up the full area (room).
The use of dirt sensors verifies the exact timing to clean the room. It means after that particular time the Roomba will automatically realise that the cleaning process has been finished and it will stop working. The dirt sensor may turn on the intensive cleaning automatically at an extensive dirty place. No need to worry about it. It’s both for the good cleaning and finishes cleaning in time.
Roomba Room Mapping
One of the most brilliant features of Roomba is to act like a human. Not only sensors Roomba has an internal system based on the vision simultaneously localization and mapping (VSLAM). It gives Roomba an edge over the sensors based system to complete the cleaning process. This process is more reliable than the sensor timing method. So based on VSLAM the Roomba will be more sure that the cleaning process is finished nor it can stop.
This technology hasn’t been found in the old versions of the Roomba. With this technology, Roomba can mad the whole room and after the cleaning process is finished the Roomba recheck if any place remained unclean. The mapping of the room map allows the Roomba to locate the places where the cleaning has not been done.
In this way, Roomba will clean all the remaining unclean areas and stop working. That is how Roomga has been improving from time to time to act more like a human.
Conclusion
Many indicators help Roomba to stop working. These include a battery, full bin, sensors activation, as well as VSLAM based room mapping. The VSLAM based method is most optimal to detect if the cleaning is complete or not. With the technology, Roombas are also improving and acting more like a human than before.
