Roomba

The device is a disk 34 cm in diameter and up to 9 cm in height. A large contact sensor is installed in the front of the device, with an infrared sensor centered in the upper front part. On the device at the top is a pen. Depending on the model, it comes with one or two infrared sensors “virtual wall”, and some models with “virtual walls - beacons”.

The first and second generation of the model needed to manually indicate the size of the room by area , for this three buttons were used on the case: (small, medium, and large), but this was no longer necessary with the release of the third generation of the device.

Roomba uses internal batteries for operation and needs regular recharging from the wall module. New third-generation models have the ability to search for a charger by communicating with it through an infrared sensor. Charging from the mains takes about three hours. Charging devices of the first and second generation lasted 12 hours, but the new charger can be used with outdated models.

The third generation device is controlled by the owner by pressing the "Power" button, having previously placed the device where he would like to clean. Then you need to select the operating mode of the device by pressing the “Cleaning”, “Spot cleaning” or “Full cleaning” button (if available). Third-generation devices allow you to clean automatically using the task scheduler. This can be useful for those people who want to schedule cleaning at a time when they are at work.

When the “Clean,” “Spot Clean,” or “Full Clean” button is pressed, Roomba beeps and then starts. The sensor on the bumper allows you to register impacts on walls and furniture, the “virtual wall” and limit with the infrared sensor those areas where cleaning should be done. The special program “Virtual Wall” can be programmed in advance in order to turn on at the moment the device is automatically turned on by the task scheduler. Four infrared sensors at the bottom of the device prevent it from falling off the stairs. Models of the third generation are able to detect accumulations of dirt, and pay more attention to such places.

At the end of the cleaning, Roomba beeps. If the charger is not found, Roomba will search for it. The owner must empty his dust bin in the trash. With the exception of the first generation Roomba, an infrared remote control allows you to configure the device remotely, which can be useful for people with disabilities . Remote control cannot be used on the line of “virtual walls” or at the device’s charging modules due to the interference they create.

Roomba has a small height. It is low enough to fit under a bed or other furniture . If he realizes that he is stuck, he will stop moving, and will begin to give sound signals that help the owner to find him.

“Helicopters” are small side brushes that sweep debris into the space under Roomba, where it is picked up by a central brush and transferred to a garbage container. The suction function in this case is not basic, but only allows to increase the cleaning efficiency.

700th Series since 2011

Since 2011, the 700th Roomba series of robotic vacuum cleaners has gone on sale, which has the following improvements:

• a new battery consumption system (with which increased operating time by 30%),
• three-stage cleaning system, a new HEPA filter (prevents dust recirculation with air flows around the house, 99.8% air purification),
• improved motion algorithms (the robot is able to clean a large area),
• a new brush unit (improved cleaning of both large debris and wool, as well as increased durability),
• added ultrasonic sensors.

The assortment of the 700th series: 760, 770, 780, 790 models.

• Easy-to-clean brush: A brush suitable for collecting pet hair.
• Remote control: control Roomba remotely (for all models of the second and third generation Roomba).
• IRobot Scheduler: the ability to schedule Roomba to schedule.
• Charging module with infrared beacon: Roomba will automatically return to the charger (for all third-generation models).
• Virtual Wall: Used to limit Roomba's cleaning areas (for all models).
• Beacon: used to separate Roomba sequential cleaning areas (new third-generation models)
• Enhanced power supply: rechargeable batteries for all Roomba models, allowing the device to work up to 200 minutes.

Roomba manufactured after October 2005 contains software that allows you to access to control and modify Roomba's behavior and remotely receive sensor signals. The open iRobot Roomba interface, formerly known as the Roomba Serial Command Interface , is intended for programmers who can make improvements to the robot software ^[1] .

System programming of the robot is done on Microsoft Robotics Developer Studio .
