Can Robot Vacuums Cross Thresholds And Efficiently Clean Your Home?

When it comes to cleaning uneven floors in your home, a robot vacuum can be a real game-changer. These handy little devices can navigate around obstacles, map out your home, and even schedule cleaning routines. But what about thresholds? Will a robot vacuum be able to cross over these raised surfaces and clean both sides of your home?


Can robot vacuums cross thresholds?

Almost always, yes, but it depends on the vacuum robot you choose. Some models are more robust than others, while others may need help to overcome this type of obstacle in some other way. Factors such as the height of the threshold, the material it’s made of, and the robotic vacuum’s suction power can all play a role in whether or not it can successfully cross over.

If you have multiple levels in your home, consider robotic vacuum cleaners specifically designed to navigate obstacles and cross smaller or higher thresholds. These models often have cliff detection sensors, low profiles, and powerful suction to ensure they can easily clean both sides of your home. By choosing the right robot vacuum cleaner, you can enjoy a clean home without worrying about whether it can navigate around your thresholds.

What is a threshold?

A threshold is a raised barrier or material strip separating two different floor surfaces. They are commonly found at doorways, where they help to prevent drafts and maintain temperature control. Thresholds come in various heights, materials, and shapes, affecting a robot vacuum’s ability to cross them.

Types of thresholds

There are several types of thresholds that you may encounter in your home, including:

  • Hardwood floor transitions
  • Plastic thresholds
  • Door thresholds
  • Room separators
  • Recycled rubber safety ramps

Each of these thresholds has unique characteristics that can affect a robot vacuum’s ability to cross them. For example, hardwood floor transitions may have fibers that can get caught in a robot vacuum’s wheels, while plastic thresholds may be slippery and cause the robot to lose traction.

Factors that affect a robot vacuum’s ability to cross thresholds

Several factors can affect a robot vacuum’s ability to cross thresholds, including:

Threshold height

  • Most robot vacuum cleaners can cross thresholds up to a certain height. For example, the Roomba robot vacuum threshold is 5/8in or 15.8mm.

Threshold ramps

  • Some thresholds may have ramps that make them easier to cross.


  • Other obstacles, such as steps or drop-offs, can affect a robot vacuum’s ability to navigate thresholds.


  • The material of the threshold can affect a robot vacuum’s traction and ability to cross it.

  • Placing a carpet or doormat over the threshold can make it easier for a robot vacuum to cross.

Most robot vacuum cleaners and vacuums can cross thresholds in most cases, but height, material, and other factors can affect their ability. By understanding the different types of thresholds and the factors that affect a robot vacuum’s ability to cross them, you can help it navigate your home more effectively.

Tips for using a robot vacuum on thresholds

When using a robot vacuum on thresholds, there are a few things to remember to ensure it can maneuver smoothly and effectively. Here are some tips to help you get the most out of your robot vacuum:

Measure your thresholds

Before purchasing a robot vacuum, it’s essential to measure the thresholds in your house to ensure it can cross them without any issues. Most robot vacuums can cross thresholds up to 2.5 inches, but if your thresholds are higher, you may need to consider other options.

Clear the area

Ensure the area around the threshold is clear of any obstacles, such as furniture or rugs. This will help the robot vacuum maneuver around both small and high threshold more efficiently and prevent bumps or collisions.

Use a ramp or low-pile rug.

If your thresholds exceed 2.5 inches, you may need a ramp or low-pile rug to help the robot vacuum cross them. A ramp can be placed on either side of the threshold to provide a gradual incline, while a low-pile rug can be placed over the threshold to give a smooth surface for the robot vacuum to cross.

Schedule cleaning times

To avoid any issues with the robot vacuum crossing thresholds, scheduling cleaning times when you’re not at home is a good idea. This will give the robot vacuum plenty of time to navigate around your home and cross any thresholds without interruption.

Follow manufacturer instructions

Finally, following the manufacturer’s instructions when using a robot vacuum on thresholds is essential. This will help ensure the robot vacuum operates as intended and the device doesn’t get stuck or damaged while crossing higher or smaller thresholds.

Following this great tip, you can help ensure that your vacuum robots can easily navigate your home and cross thresholds, making cleaning a breeze.


In conclusion, robot vacuums have come a long way in their ability to navigate obstacles and cross thresholds in a home. Most robot vacuums are designed to clean only one level of a home, but some newer models have been designed with multiple levels in mind and can cross thresholds between rooms or floors.

Regarding going over thresholds, robot vacuums are generally designed to handle bumps and transitions efficiently. However, the height and type of threshold can affect how well it can maneuver. If you have a lot of high thresholds in your home, it may be worth investing in a robot vacuum cleaner with a higher threshold height clearance.

The best robot vacuums, such as the iRobot Roomba and the Neato Botvac D80, are designed with powerful suction and brushes for cleaning on both hard floors, wood and carpets. They also feature edge-sensing technology and cliff-detection sensors to prevent falls and damage to furniture.

Regarding cleaning efficiency, robot vacuums are designed to pick up debris, fibers, and dust from floors and carpets. They also can schedule cleaning routines and self-charge when needed.

Overall, the market for robot vacuum cleaners is constantly evolving, with new models and features being introduced regularly. When choosing the best robot vacuum for your home, consider factors such as the maximum height of the threshold, flooring type, and customer service. With the right robot vacuum, you can enjoy a clean home without the hassle of manual cleaning.
