Will a Robot Vacuum Fall Down the Stairs?

One of the most common questions we hear from people is “will a robot vacuum fall down the
stairs?” The answer depends on the type of staircase you have, the condition of the carpet, and
the type of flooring.

If the stairs are dark, the robot will not be able to detect them and may fall. The sensors can also be covered, which will prevent the robot from detecting stairs, and may even cause it to fall down the stairs. If you want to avoid this scenario, you can install physical or virtual barriers on the stairway.

Install a virtual wall

The robot vacuum can be programmed to avoid stairs, but it has a higher risk of falling down
them. You can install a Virtual Wall near the stairs to make it impossible for the robot to fall down
the stairs.

But you must ensure that the carpet is not very rough, as this can interfere with the sensors. If you don’t have a staircase, you can place a barrier over the sensor, but the robot will still fall down the stairs.

In order to prevent the robot vacuum from falling down the stairs, you should make sure that you
have placed it in a location where it will not be tripped by anything. If the stair is made of rough
carpet, this will affect the sensors.

If you have carpet, you can cover the sensors by taping them down. But if you live in a house with stairs, you should not do that. Otherwise, the robot will fall down the stair and may not even be aware that it is doing so.

Robot Vacuum uses Infrared sensors

Robot vacuums that use infrared sensors are less likely to fall down the stairs, although they do
fall down occasionally. This is because the infrared sensors are more accurate when they’re
close to the surface, but not if they’re further away.

For example, if you have a flat floor without stairs, you can tape over the sensors if they don’t work. If you have a staircase, you can ignore the infrared sensors, but the robot will still fall down the stairs if it detects that the staircase is a vertical wall.

The chances of the robot vacuum falling down the stairs are lower when the robot has the fall
detection technology. However, you should keep the robot clean, as it has a rotating brush and
the hairs on the brushes can be caught on a bolt and cause the robot to fall.

If the robot’s aren’t in a position to be tucked under carpet, you should tape them over the stairs to avoid the risk of the fall. The robot vacuum with infrared cliff sensors is likely to fall down stairs. However, this is an exception. Often, the robot vacuums will fall down a staircase if the staircase isn’t particularly slippery.

The best robots have no problem with falling down stairs, but you should make sure they’re clean and neat before letting them out of the house. If your stairs aren’t safe, you can force them to clean the area by putting a virtual wall on them.


While there’s no evidence that robot vacuums will fall down the stairs, it’s important to keep them
clean and in a place where they can’t fall down. The most reliable robots are those with infrared
cliff sensors.

While they won’t fall down the stairs when they’re clean, they can still fall. In such
situations, it is important to use a device called the Virtual Wall.

Depending on the design of your staircase, the probability of a robotic vacuum falling down the
stairs is very low. The first thing you can do is set up a Virtual Wall. This device creates an
invisible 10-foot barrier around the stairs.
