How Does Roomba Work on Carpets?(Comparing All Models)

Last updated on February 15th, 2024

Some of the higher-end range Roomba models like s9+/i7+ work efficiently on carpets. But have you ever wondered how does Roomba work on carpets? Does their cleaning efficiency remain the same or change on different surfaces? In this article, we will explore how these robots work on carpets and their cleaning efficiency on different types of carpets.

Yes, various Roomba models like j7+, s9+, and i7+ are efficient in cleaning carpets. These models are designed in such a way that the robot adjusts the height of the cleaning head when the carpet is detected by its sensors. It should be noted that not all Roomba models can clean the carpets efficiently.

Some of the top models that are efficient in cleaning carpets are shown in the table below.

Roomba ModelFeatures
Roomba s9+Advanced mapping technology, self-emptying bin, powerful suction, tangle-free brushes
Roomba i7+Advanced mapping technology, self-emptying bin
Roomba 980Powerful suction, tangle-free brushes
Roomba 960Strong suction, high-efficiency filter
Roomba e5Rubber brushes for pet hair and long fibers
Roomba 675Multi-surface brushes, adaptive navigation

How does Roomba work on carpets?

Roomba uses two main features: adjustable cleaning heads and variable suction power to clean a carpet efficiently. As soon as the sensor detects a carpet in the floor space, it automatically adjusts these two features to clean different types of dirt and debris from the carpet.

Understanding the working

These vacuum robots are equipped with specialized sensors, that easily detect different types of surfaces. So when a carpet is detected, the suction power and height of the cleaning head change according to the carpet’s height, and the robot enters a deep-cleaning mode. It follows a systematic cleaning pattern while cleaning the carpet. The corners of a carpet get cleaned with the help of edge-sweeping brushes. In this way, a Roomba cleans a carpet.

Can Roomba clean all carpet types?

The carpets in your home can have different heights, it could be low-pile, medium-pile, or high-pile carpet. Based on the thickness of the carpet, the efficiency of Roomba may vary. Though these robot vacuums can easily climb onto a carpet size of up to three-quarters of an inch (around 20mm) and continue their cleaning routine, they may not be able to pull out the dirt stuck deep in a thick carpet.

How does Roomba work on thick carpets?

Higher-quality Roomba models are generally more effective at handling high-pile carpets, while other robotic vacuums may not perform as well. A Roomba must have good airflow, powerful suction, dual turbines, or similar capabilities that can effectively clean thicker carpets.

For example, the Roomba s9/s9+ has 40 times more suction power and three times better airflow than the Roomba 600 series. So it can clean a thick carpet more efficiently.

However, when a carpet becomes excessively rough, it may be difficult for a robot vacuum to handle it and may require alternative cleaning methods like manual vacuuming, or specialized carpet cleaning equipment.

Roombas getting stuck on rugs & tips to avoid it

Thick or high-pile rugs with long fibers might make Roomba’s mobility difficult as they get tangled in the brushes or wheels of the Roombas. Though newer Roomba models have enhanced sensors and software algorithms to address this issue, a Roomba can still get trapped on some carpets. If your Roomba routinely gets stuck on rugs, try the following strategies to help:

  • Tie down loose rug edges: If the rug contains fringes or tassels, try using rug tape, or any other method to secure them to the rug’s body. This reduces the possibility of the rug becoming entangled with the Roomba’s components.
  • Elevate the rug: If the rug is small enough, consider raising it by laying it on top of a non-slip mat or securing it with double-sided tape. This decreases the likelihood of Roomba becoming entangled on the rug’s edges.
  • Use virtual wall barriers or magnetic strips to establish boundaries: Some Roomba models usually come with virtual wall barriers or magnetic strips that can be used to create boundaries. With this, you can create no-go zones for your robot and avoid those places where it gets stuck.
  • Supervise or use manual mode: If you have some carpets that are difficult to clean, you may supervise Roomba’s cleaning sessions to guarantee no problems arise. Alternatively, certain Roomba models include a manual mode that lets you directly control the vacuum’s movement.

Note: You can make a schedule to manually clean the robot’s sensors, brushes, wheels, and other movable parts. This reduces the chances of loose fibers getting stuck on them.

Why is my Roomba avoiding my carpet?

There are several reasons why your Roomba may be avoiding your carpet. or any specific part of the carpet:

  • Variable rug height: Sometimes due to the carpet’s varying height or texture, the robot’s sensors may perceive it as an obstacle and avoid cleaning that specific part of the carpet.
  • Furniture or object: If there are toys, furniture, or any physical object on the carpet, the robot may not clean that area.
  • Power settings: For successful carpet cleaning, ensure that you have selected the proper power setting or carpet boost mode. If that mode is automatic, make sure that the Roomba is in the deep-cleaning mode.
  • Virtual walls or boundaries: Check whether you’ve created any virtual walls or borders that are restricting your Roomba movement on the carpeted areas.
  • Sensor failure: If the problem persists, it might be a sensor failure, and you should contact the manufacturer for assistance.

Note: Roomba robots often avoid cleaning dark-colored carpets because their sensors perceive them as potential hazards or obstacles.


Does Roomba work on a thick carpet?

Not all Roomba models can work on thick carpets, only those models with advanced technology, equipped with high suction power and dual turbines, excel at efficiently cleaning thick carpets.

Do robot vacuums mop carpets?

No, robot vacuums do not mop carpets because their cleaning mechanisms are primarily designed for dry vacuuming rather than wet mopping.
