Robotic vacuum cleaner

A robotic vacuum cleaner, often called a robovac, is an autonomous robotic vacuum cleaner which has intelligent programming and a limited vacuum cleaning system. The original design included manual operation via remote control and a "self-drive" mode which allowed the machine to clean autonomously without human control. Some designs use spinning brushes to reach tight corners. Others include a number of cleaning features (mopping, UV sterilization, etc.) along with the vacuuming.

In 1996, Electrolux introduced the first “Robotic Vacuum Cleaner”. The early robotic vacuum cleaners worked well but had frequent problems with colliding with objects and stopping short of walls and other objects, as well as leaving small areas not cleaned. As a result, the original product failed in the market and was discontinued.
In 2002, iRobot, an American advanced technology company, launched the Roomba. The Roomba was able to change direction when it encountered an obstacle, detect dirty spots on the floor, and detect steep drops to keep it from falling down stairs. It became popular very fast, which then caused other companies to reconsider the idea of a robotic vacuum cleaner.
An advantage using a Robotic Vacuum Cleaner is how quiet it is compared to regular vacuum cleaners. Also, they are seen as more convenient to use due to the fact it can vacuum on its own. Robotic vacuums can be kept under beds, desks, closets, whereas a regular vacuum cleaner requires a large amount of space. However, a downfall to a robotic vacuum cleaner is that it takes a longer amount of time to vacuum an area due to how small it is. They are also relatively expensive.
The first robot cleaner to be put into production was Electrolux Trilobite by the Swedish household and professional appliances manufacturer, Electrolux. Electrolux was successful in purchasing the model from its inventor, James Dizon. In 1996, one of Electrolux's first versions of the Trilobite vacuum was featured on the BBC's science program, Tomorrow's World.
In 2002, the American advanced technology company, iRobot launched the Roomba floor vacuuming robot. iRobot was founded in 1990 by three roboticist name Colin Angle, Helen Greiner, and Rodney Brooks. The company was originally dedicated to making robots for military and domestic use. The Roomba wasn’t the first robot vacuum, but it was the most successful, selling up to a million units in 2004. In 2005, iRobot created the Scooba which was the opposite of the Roomba as it scrubbed hard floors. A year later in 2006 they released the Dirt Dog which was able to clean up debris. The company wanted to make doing chores as simple as possible.
Initially, iRobot decided to produce 15,000 units and 10,000 more units depending on the success of the launch. The Roomba immediately became a huge consumer sensation. By the Christmas season, iRobot produced 50,000 units to meet the holiday demand. After this success, major specialty retailers, as well as more than 4,000 outlets such as Target, Kohl's and Linens 'n Things, began to carry the Roomba.
Since 2002, new variations of robotic vacuum cleaners have appeared in the market. For example, the Canadian bObsweep robotic vacuum that both mops and vacuums, or the Neato Robotics XV-11 robotic vacuum, which uses laser-vision rather than the traditional ultrasound based models.
In 2014, Dyson announced the release of its new robotic vacuum called Dyson 360 Eye, equipped with a 360-degree camera that is mounted on the top of the robot vacuum cleaner and is supposed to provide a better navigation than other brands. The robot vacuum was scheduled for a Japan-only release in spring 2015 with international launches to follow later in the year. Moreover, Dyson announced that the 360 Eye has twice the suction of any other robot vacuum. Dyson is leading the robotic vacuum market towards the goals of achieving a reliable and capable unit. The company is investing robotics and AI to produce better robot vacuum cleaners in the coming years. It has initiated the establishment of a new campus in the UK which will require a workforce of around 7000 and an investment of £330 million to create a wider research facility in Singapore focusing on “connected technology and intelligent machines.”
As of 2018, obstacles such as dog dirt, cables and shoes remain very difficult for robots to navigate around, according to PerceptIn CEO Zhe Zhang.
iRobot: Mopping Scooba
The iRobot first premiered with the self-mopping robot, Scooba, in 2005. The robot was made to be a self-regulating mop. The Scooba would go through many different changes through the years.Including the Scooba 450, released in 2014. In 2016 iRobot discontinued the Scooba line in favor of Braava. Braava has a implemented wall charger, it has no sensors and uses cotton swabs to clean instead or brushes. In 2018 the Braava Jet 240 received its own app. Braava sales has risen 65-percent since 2016.
Sweeping and Mopping Braava
Braava 380T is a high end model of the late stages of the iRobot. The Braava 380T has the ability to do two options in the same pass, which are, sweep and mop. The device has the efficiency to hold a battery life of up to around 4 hours. iRobot Braava 380T uses an innovative technology called “North Star navigation”. The North Star in this context is a special high tech cube. The cube gives a signal which iRobot uses to position itself in the room. It will know where exactly in the room it is and which part of the floor it has mopped or swept. The manufacturer described it as a GPS system for home robots, which is a great analogy.
Cleaning types usually include auto mode for general cleaning, scheduled mode, turbo (maximum clean), edge clean for skirting boards and corners, area cleaning mode for cleaning designated areas, spot or spiral mode for spot cleaning a particular zone, and remote mode, allowing the user to steer the robot to a particularly dirty spot.
Some models can also mop for wet cleaning, autonomously vacuuming and wet-mopping a floor in one pass (sweep and mop combo).
The water could creep to the mop gradually, does the mopping as the human beings.
A Robot Mop can tackle multi surfaces and comes with a variety of different cleaning modes giving you options of sweeping, vacuuming and mopping damp or wet floors. The Robot Mop score better on hard floors surface and are ideally suited for hardwood, laminate and tile flooring types
Most robots include anti-drop and anti-bump IR sensors.
When approaching obstacles, will automatically revolve away.
Prevents the robot getting twined by wires.
The first robovacs used random navigation. This sometimes caused the unit to miss spots when cleaning or be unable to locate its base station to recharge, and did not provide the user a history of which spaces were cleaned.
More sophisticated models include mapping ability. The unit can use gyro, camera, radar, and laser (laser distance sensor or LDS) guided systems to create a floor plan, which can be permanently stored for more efficiency. These vacuum robot has memory, knowing where has been cleaned, where has not, Thus the cleaning efficiency is greatly improved and the repetition rate is reduced significantly.
Models with a multiple floor plan feature can store several floor plans.
Virtual No-Go Lines
Virtual No-Go lines set boundaries, to restrict the unit's movements to desired cleaning areas.
The 2000 mAh Lithium battery lasts long enough to handle a big house of 200 m² (about 100 minutes).
Regular charge time is 5 to 6 hours.
Quick recharge allows the unit to calculate the shortest way to recharge (shortcut path) and charge only as much as needed, so it finishes more quickly (automatic cleaning resumption).
A D-shape design can help capture dirt in corners and along walls better than some round units.
Scheduled daily cleaning. All-Timetable means a full week of different daily schedules can be programmed.
Some units are able to receive over the air (OTA) firmware updates.
Chinese robots have dropped prices, mainly in mapping robots.
