How Do Robot Vacuum Cleaners Work

Your little robot vacuum rolls around your smart home, happily picking up dust and debris,

doing its job when scheduled,

Ever faithful and always on the search for more dirt.

But have you ever stopped to think about what goes on in its robot body?

Or how it works?

We don’t often think about what makes these little helpers tick. We just let it do its job and enjoy the results, knowing that we didn’t have to do the job ourselves. They map our homes and know the layout of our rooms, and yet what do we really know about them?

Well, we are here to clue you in on how a robot vacuum cleaner does its job.

Most robot vacuum cleaners run on a rechargeable NiMH battery.

How much runtime they have depends on the capacity of the battery.

Some will even dock themselves into their charger and juice up all by themselves. Most have a movement system that uses motor-driven, tracked wheels and they steer by alternating the power to each. This is how they can turn so tightly.

Navigation sensors collect environmental data and send it to the robot’s microprocessor.

In this way,

The robot can map your entire home, knowing where everything is:

  • where the wall is
  • how large the room is
  • where it can move freely.

In this way, it knows the area that it is free to vacuum.


It can even adapt to obstacles that weren’t there before, like a shoe that you left in the way or a chair that has been moved. Those sensors also help it detect things like tassels on rugs, power cords and more. Cliff sensors mounted underneath, point straight down so that your robot vacuum knows if it is on stairs and if there is a steep drop.

Sensors also help your cleaning robot to know when it has hit a particularly dirty area.

When dirt hits the sensor,

It knows how much dirt is there and if it senses a lot, the robot will linger in that area for longer.

Like a conventional vacuum, it uses spinning bristles and a vacuum to suck up dirt.

Most have a side-mounted brush that pushes dirt beneath the machine and then more counter-rotating brushes pick up the dirt and send it to the vacuum, which deposits it in the collection bin.

Though technologically complicated, as you can see, the way that robot vacuums work is fairly simple and straightforward.

Now that you have a better idea of how robot vacuum cleaners work, maybe you can appreciate the things they do for us a bit more.

Like regular vacuum cleaners, along with some other filters in the home, these robot versions help keep our homes a bit more allergy free and ask any allergy sufferer, that is a good thing. Look for one that has AAFA certification

These robots are just a small part of the current home automation trend of devices that make our lives easier.

They may not record TV shows, help to improve our home security, do our laundry or cook our meals, but they are still worthy of our admiration.

So take a moment to just appreciate how these little devices save us some hassle.
