How a robot vacuum works

A robot vacuum vacuums the floor. That much is clear. But how exactly does the robot do that? In this article, I'll give you more information about the ways robot vacuums find their way around the house and how this affects the quality of the robot. In addition, there are several cleaning and suction methods.

Navigation method

The navigation method indicates the way the robot moves around the house. If a robot doesn't have a navigation method, it drives around the house at random. You can get these robots at a lower price, but there is a chance it will skip parts. If the robot does have a navigation method, there are 4 different options.

Self-learning and GPS chip

Self-learning

A robot vacuum with a self-learning navigation method has a memory function. That way, it can save the route through the house and basically 'remembers' where the obstacles are. It's possible that the robot vacuum has to drive around the house the first couple of times to learn the route. As a result, there is a change the robot skips parts the first times.

GPS chip

A GPS chip is in the robot and uses location services to keep track of the whereabouts of the robot and which route it's taking. To use this navigation method, the robot vacuum needs a good WiFi connection.

Ceiling recognition and laser

Ceiling recognition

The robot vacuum maps the room by scanning the ceiling with a camera. The robot vacuum works systematically and maps obstacles. Most robot vacuums with ceiling recognition store the data. In this way, the robot basically 'remembers' the obstacles in the room so it can drive around them.

Laser

The robot vacuum uses an invisible laser beam to map the room. Robot vacuums with this navigation method also use the laser to select the most efficient route. For example, if the battery runs out and the robot vacuum is capable of returning to the charging dock itself, it uses the lasers to determine the shortest route.

Cleaning routes

When the robot vacuum has mapped the room, it drives around the house to vacuum the floor. The robot vacuum can follow different cleaning routes: random and systematic.

Random vs systematic

Random

The robot vacuum doesn't have a specific cleaning route and drives around the house at random. In general, you can get robot vacuums with random cleaning routes at a lower price. The disadvantage is that the robot vacuum cleaner may miss or skip spots.

Systematic

A robot vacuum cleaner works systematically if it zigzags through the house, so it can get everywhere. If you want to be extra sure that the robot vacuum cleaner doesn't skip any parts, you need a robot with a systematic cleaning route.

The more, the better

Advanced robot vacuum

The more advanced the robot vacuum is, the more systematic the cleaning route and the better the navigation method. Most basic robot vacuums only have a random cleaning route. Better robot vacuums work more systematically. You can find which cleaning route and navigation method the robots have in the manuals on the product page.

Suction method

By suction method, I mean the way in which the robot vacuum cleaner picks up dust from the ground before it ends up in the dust cup. In some cases, side brushes bring the dirt to the suction brush, while some robot vacuums have a brush inside the suction brush as well.
