Can Roomba Detect Stairs? All You Need To Know

Can Roomba Detect Stairs? Most robot vacuum cleaners are equipped with “break sensors” designed to prevent them from falling down the stairs.  In fact, over the years, sensors have become more sophisticated, so robot vacuum cleaners almost never fall off the stairs.  However, outdated models can fall off the stairs.

Can Roomba Detect Stairs?

Currently, robot vacuum cleaners are equipped with several sensors that collect useful environmental data.  Most robot vacuum cleaners not only have mapping technology, but also have several sensors that help them navigate. One such sensor is a break sensor designed to measure the distance between the robot and the floor.  Rock sensors are infrared sensors installed under a robot vacuum cleaner.  It is directed downwards so that the robot vacuum cleaner can detect stairs or steep falls, as falls can cause serious damage to the robot.

What Is Best Roomba To Detect Stairs?

Nowadays, it is rare to see a robot vacuum without cliff sensors. But the Roomba e5 Series is well equipped with cliff sensors that prevent it from falling down stairs. You can have peace of mind knowing that this robot vacuums is equipped with cliff sensors. Also check the 5 Best Roomba with Mapping 

How Do The Roomba Cliff Sensors Work?

The rock sensors work by constantly emitting infrared light.  This light returns to the device immediately.  If it doesn’t get an answer, it knows a cliff is approaching.  After that, the robot vacuum cleaner will stop and change direction.  Sensors are placed on the edges of the device to prevent it from escaping

Nowadays, it is rare to see a robot vacuum cleaner without break sensors.  In fact, the Roomba 500, 600, 700, 800, 900, e Series and i Series are equipped with breakage sensors that prevent you from falling down stairs.  You can rest easy knowing that most robot vacuum cleaners are equipped with break sensors.

Will Roomba Fall Down The Stairs?

Roomba 980 is equipped with built-in Cliff Detect sensors.  These Cliff Detect sensors detect when the device is on a higher surface and must be lowered to continue to operate.  When Roomba 980 discovers the stairs, it begins to roll over the descents.

The rollover function protects the Roomba 980 from any damage or breakage, so it continues to run smoothly and cleans your stairs from every angle.  This frees your home from dirt and is actually the best device for automatic floor cleaning.

This way, you can use the Roomba 980 without fear of it falling off the stairs and stopping working or something because it won’t.  Roomba 980 is already designed to stay away from stairs.  The Cliff Detect sensor will detect altitude and allow Roomba to change direction and move away from the stairs.  Cliff Detect sensors are very efficient and detect stairs quickly.

How Reliable Are Roomba Cliff Sensors?

These iRobot Roomba vacuum cleaner sensors are considered to be quite reliable in typical operating conditions.  However, they can become covered in dust and dirt after a while during gadget vacuuming sessions. If the remnants interfere with the device’s breakage sensors, it’s likely that they’re having trouble sending and receiving infrared signals that allow the gadget to detect that it’s near the ground.

Why Does My Roomba Fall From The Stairs?

It depends on whether your stairs have a carpet, whether they are made of wood and so on.  And, of course, the type of roomba vacuum cleaner.  But as a general rule, you would first need to keep your robot vacuum neat. As you may know, the device below has lots of brushes that are constantly rotating. If you let too many hairs get inside of it, your robot vacuum could get trapped on a bolt and it will catapult right to the first floor.

Secondly, the break sensors.  When your device is brand new, you will not experience these problems, but in six months or even a year.  This can be a problem  These sensors are contaminated for many reasons.  If you accidentally spill the juice and vacuum it, it will cover the glass with a sticky layer.  And when he climbs the stairs, you will see him fly!

How To Prevent Roomba From Falling Down The Stairs?

Clean the Roomba sensors

To prevent the roomba from falling down the stairs, the first thing you need to do is clean the Roomba break sensors regularly.  This will greatly help you stop Roomba from falling down the stairs.  Because Roomba break sensors are the only way to detect stairs and stones, he may have trouble determining the boundaries of stairs if they are dirty.

Break sensors also have problems on black or dark carpets.  Start by turning the vacuum cleaner upside down to clean the break sensors.  Using a clean, dry cloth, wipe each break sensor.  To prevent the roomba from falling off stairs and edges, regularly clean the sensors on it, especially the break sensors.  But be careful.  Water can get into the room and damage it.

Install a virtual wall barrier

For your Roomba, iRobot has technology that can create an invisible wall called a “virtual wall”.  The iRobot Virtual Wall Barrier is compatible with Roombas 600, 700, 800 and 900 series. It’s easy to set up and your Roomba won’t cross the border.  It runs on a pair of conventional AA batteries and does not require recharging.

You don’t have to worry about Roomba falling if you install virtual wall barriers in front of your stairs.  If you allow the device to run out, your Roomba will ignore it.  In general, this is a very flexible solution.  This allows you to fine-tune the wall to your specific needs.  This way, you can install a virtual wall to prevent the roomba from falling down the stairs.

Remap your home

Roombas are able to outline your entire home.  However, they may not always accurately reflect your home.  Open doors in them can be considered a wall.  They could miss this part of the house the next time they vacuum.

The easiest way to fix this is to ask your Roomba to reassign the area where your stairs are located.  This is especially important if there is already a physical or virtual barrier in the way of the stairs.  Roombas make mistakes and don’t always tell the difference.  So to prevent roomba from falling down the stairs, you can reassign your roomba from i-Robot.

Replace non-functional cliff sensors

Because the Roomba break sensor is so sensitive, it usually breaks for many users.  Fortunately, this also means that finding new components is easy.  To replace a broken Roomba sensor, you can purchase a “caSino187 Cliff” and a bumper.  They are suitable for a wide range of Roombas, and they are easy to configure even for non-technicians.

It’s as simple as unplugging Roomba, unplugging old ones, and plugging in new ones as soon as you get replacement sensors. This process takes only a few hand tools and a couple of hours.  The useful iFixit guide will walk you through the whole process.  The sensors are connected to the computer’s motherboard via a standard contact connector.  Old sensors are easy to remove, but be careful not to damage the motherboard.

Remove any carpets from the area around your stairs.

Your Roomba believes that your black carpet is a rock, which is an interesting fact.  Because the breakage sensor cannot detect light reflected from black surfaces, it avoids this area.  However, this is not always the case.  The ability to distinguish between carpet and rock has improved significantly in the latest model roombas.  But there is a catch.  A dark carpet may be visible to your Roomba, but the stairs will seem part of your carpet.

Instead, make sure you have a bright rug.  Roombas are best complemented by white, ivory, beige, gray and pastel shades.  You can save your comfortable stairs without turning off your Roomba.

Can Roomba Detect Stairs FAQs

How Does Roomba Sense and Avoid Stairs?

Robot vacuum cleaners are equipped with convenient break sensors that prevent the approach of an automatic vacuum cleaner near the ledges and stairs.  They do this by transferring data to a small microprocessor inside the device, which uses the information to change the cleaning path.

Four small infrared sensors on the front panel and under vacuum prevent the device from hitting objects when crossing the floor.  Moreover, if he thinks that there may be a ladder, the vacuum cleaner will stop and “think” about it – will process the sensor data – to be doubly sure that he will not fall down the stairs.

How Good Is Roomba With Stairs?

Your Roomba should recognize the stairs thanks to the break sensors we just mentioned.  These sensors are located at the bottom of the Roomba.  At the front edge there are three or four sensors to detect any rocks or protrusions.  When the landing is found, Roomba must retreat safely.

How Do You Keep A Roomba From Going Down Stairs?

You can also change the way you clean Roomba with strategically placed items such as furniture or books.  Placing items along the top of the stairs can prevent Roomba from falling down the stairs.


Can Roomba Detect Stairs? They are really equipped with break sensors that prevent them from falling down the stairs.  Such sensors are able to stop the work when it approaches the ledge – so they can be useful in residential areas that emit stairwells.  However, these robotic vacuum cleaners from iRobot can still face problems if they are left unattended for a really long time.

If the robot is facing the flight of stairs and is so that it does not fully extend beyond the edge of the steps, its break sensors will inform the AWARE system that the distance between the ground and break sensors has increased.

As soon as the AWARE intelligent system receives information that the gadget is in danger of falling, it will find a way to safely move the car away from the edge of the steps. Such protective lighting should protect the robot vacuum cleaner, as it – for a short time remains unattended and is useful for vacuuming houses with ledges or stairways.
