8 Best Robot Vacuums for Thick Carpet

Robot vacuums have been revolutionary, and there’s nothing better than being to sit down and relax while your vacuum does the work by itself.

They come in many designs, but most of them are ideal for smooth surfaces or thin carpets, meaning they might struggle with thicker carpets.

In fact, it can be hard for the robot vacuum to reach the entirety of the thick carpet’s fibers, which then leads to a lot of dirt getting accumulated, unable to be cleaned up.

Over time, this will severely damage your carpet, and it will make using the robot vacuum a bit of a frustrating fail. 

The solution, however, is simple. Make sure the robot vacuum that you’re using is suitable for thick carpets.

As we mentioned, they come in many designs, so look out for one that has the necessary bristles to reach every last inch of carpet, no matter how thick. That way, you’ll be able to actually relax, knowing no amount of dirt is being left behind to accumulate.

To help you look through some of the best robot vacuums designed for thick carpets, we’ve put together a list. Just choose the one most suited to your personal preferences!

Best Robot Vacuums for Thick Carpet Buying Guide

Robot vacuums are incredibly comfortable to use, as you simply set them up, and then leave them to vacuum the house while you relax or do other things.

They’re very efficient, and can leave the house looking cleaner than ever, not to mention that a lot of them have several different advanced features that make them almost completely independent.

So what’s the issue with thick carpets? Well, most robot vacuums are designed for hard floors and low-pile carpets, as they are designed for smooth surfaces.

The issue with thicker carpets, is that if the robot vacuum isn’t suitable, it will struggle to clean them efficiently, and will likely be unable to get to the bottom of the fibers. Plus, they might also struggle with moving on them and might get caught and trapped!

To ensure the robot vacuum is suitable for thicker carpets, you need to check whether it’s compatible with medium-pile carpets, and whether it has a strong enough suction capacity that will be able to deal with that extra thickness.

However, if you want to purchase the best possible vacuum, checking whether it’s minimally suitable isn’t enough. There are plenty of other features to look out for, in order to ensure you’re getting a high-quality and reliable product, that will truly make your life easier.

Let’s look at some of the main basic factors that you can take into consideration when choosing your robot vacuum, keeping in mind that you’re looking for one that is suitable for thick carpets:

Floor Type and Cleaning Modes

The first factor to consider, is whether the robot vacuum is suitable for the type of floor you’re going to use it with. So in the case of thick carpets, you need to make sure it is apt for use on at least medium-pile carpets.

Most robot vacuums will be able to switch between flooring types, so this is definitely something to check. Some vacuums will feature an automatic carpet-boost, in which they will detect the carpet flooring, and enhance the suction power accordingly so that the cleaning remains as efficient.

A lot of robot vacuums will also have different cleaning modes, which you can set up or choose from when putting it to work. These cleaning modes relate to types of floor, but also to types of cleaning.

So for example, you might want to use a Spot cleaning mode to go over a smaller area with enhanced suctioning, if it’s an especially dirty patch of surface.

Other popular cleaning modes are Edge mode, which is to take care of the more hidden corners, or Automatic mode, in which the vacuum will follow its pre-established pattern to clean a larger area of surface.

Suction Power

Suction power is absolutely key when it comes to robot vacuums, and especially if you’re going to use one on a carpet.

On a smooth hard wood surface, there’s no need for too much suction, because the dirt has nowhere to get trapped or hold on to.

On a carpet, on the other hand, the dirt and debris will cling to the fibers that they are buried between, and more suction power is therefore needed to loosen them up and clean them.

If you have a thick carpet, of medium-pile and above, then the fibers of carpet go a lot deeper, and it’s harder for the suction power to reach the very bottom, where most of the dirt will be hiding.

So an enhanced suction power is needed in order to ensure the carpet is truly being cleaned as best as possible.

Look out for robot vacuums that have adjustable suction power, with a boost for carpet surfaces.

Battery

Battery life is quite important when it comes to robot vacuums, as they are designed to automatically go around the house cleaning everything up, and they do so by themselves without being plugged in. The more battery life they have, the more surface area they will be able to cover with each go.

Most robot vacuums will have an auto-recharge feature, so you should 100% aim to have it in yours too. It makes sure that when the power is running low, the vacuum goes back to its base, to dock and recharge. That way it doesn’t just die in the middle of a room.

If the robot vacuum is advanced enough, it will then continue right where it left off, once it’s recharged, and this is a super convenient and useful feature that we recommend you look for.

Navigation and Mapping

Robot vacuums are designed to go around the house by themselves, covering the entirety of the floor surface, picking up all dirt.

That is why, more and more, they are equipped with navigation systems, and mapping capabilities. This helps them navigate the different rooms in your house, until they know where everything is, and can therefore be even more efficient in their cleaning patterns.

The mapping function helps them get to know your house. And eventually, you should be able to schedule them to clean specific rooms or areas of the house, and they will know exactly where to go to get the job done.

Not all robot vacuums have these features, but they’re very useful, and they really do take the robot aspect to the next level. With this, you can usually set up the schedule from an app, and then sit back and relax while they go about the vacuuming.

Sensors and Protection Features

Robot vacuums don’t have eyes. (Although you could draw some on or stick some on, for fun. Just remember that they won’t actually be able to see through them.)

So they have to be able to get by through other means. It is normal, in any household, for different objects or items to be scattered around the floor, and the robot vacuum has to somehow get by, while doing its job, without getting trapped, struck, and without falling off any edges.

This is where the sensors and protector features come in. Most robot vacuums will have infrared-sensors, for objects, and will have drop-sensing technology to avoid any edges from which they could fall off.

Nevertheless, somoe vacuums are more efficient than others at overcoming these obstacles. More advanced vacuums will recalibrate their pattern and get around, over, or under.

Other vacuums will get stuck, and will be unable to move and continue vacuuming until you set them free from their situation. The latter can be very annoying and inconvenient, so always check the sensor capabilities beforehand!

Control and Scheduling

Robot vacuums can be controlled in four different main ways:

  • Manual button control:
    Most of the vacuums will have a few manual buttons to control the main features and cleaning modes. But once you have them set up, you shouldn’t have to bother with pressing an actual button on them, as there are more comfortable ways of controlling them.
  • Voice control:
    This one is very convenient, and very comfortable to use. There will be a few basic voice commands that you can use, that will vary from vacuum to vacuum, and that will allow you to control the on and off, as well as the cleaning modes and others.
    Some more advanced robot vacuums have a feature in which they can interrupt their schedule or cleaning pattern to answer to an “emergency”, such as you telling them to go and clean under the kitchen table. And once they’ve done that, they will resume their previous task.
  • App-Control:
    This is one of the most popular and commonly used. If your robot vacuum comes with this, there will be a specific smartphone app that you can download, and use to control every single aspect of the vacuum, including the cleaning modes and the schedules.
  • Connection through Alexa or Google Assistant:
    You can usually connect most robot vacuums to the Alexa or Google Assistant that you have installed in your home, and can then order it about using them. It works very similarly to the voice command.

As for the scheduling, different robot vacuums will have different capacities. More advanced vacuums will be able to schedule specific tasks, times, and rooms. And some might even begin to suggest personalized cleaning patterns, based on the parts of the house that need the most cleaning.

Dirt Capacity

The dirt capacity is the amount of dirt and debris that your robot vacuum can hold and store, before it needs emptying. The more capacity, the less regularly you will have to empty it.

Some advanced robot vacuums will have a container at their base, in which they can self-empty the dirt. That way you only have to empty that bigger container, and it’s a lot less regular. Some even have a capacity for 60 days worth of dirt, meaning you only ever have to interfere with the vacuum once every two months!

A good dirt capacity can be super convenient, but it’s not that essential. Depends on what your priorities and preferences are with the vacuum! 

FAQ's

Do robot vacuums clean in a straight line?

This depends on the robot vacuum, and its specific capabilities. Most robot vacuums will have a pre-established pattern that they automatically use for covering large surface areas.

Usually this pattern is a combination of straight lines and turns, or it could be a Z-shaped pattern.

However, if the robot vacuum has a navigation system and enough sensors, it will clean in a way that avoids the obstacles, while still attempting to get to every last bit of surface.

How often should you run the robot vacuum?

There is no exact answer to this question, as it completely depends on each house, and the specific cleaning needs.

You should run the robot vacuum as often as needed, or as often as you want it to run. A few times a week is usually the average, although there are people that like running it on a daily basis.

You could also run it more regularly in some areas of the house, and less often in others. The robot vacuum is there as a tool, and it will clean as often as you schedule it to.

Can robot vacuums clean in the dark?

Robot vacuums don’t ‘see’ where they are going, but rather, they are navigating with the help of different sensors, or with a mapping system.

So, usually, it’s perfectly fine for them to be in the dark, and they will be able to clean just as well.

However, there are some robot vacuums that use camera and laser based navigation, and these will require a minimum amount of light, even if it isn’t full of daylight.

What vacuum works best on thick carpet?

When it comes to thicker carpets, it’s important that you use a suitable robot vacuum. Otherwise, the cleaning will be inefficient, and the carpet will just be accumulating dirt and debris at the very bottom.

Look for vacuums that are suitable for carpets of at least medium-pile, or more. And look out for higher suction power, specifically, for carper auto-boost suction that will really be able to get all the dirt loose and out.

Are robot vacuums worth it?

The simple answer is: yes. Robot vacuums are absolutely worth it. They are incredibly convenient and comfortable to use, and they free up your time so that you can get on with other things while the vacuuming is taken care of by itself.

Robot vacuums are also packed with innovative technology and plenty of useful features, so they tend to have a very powerful suction capability, as well as being able to adapt to different floor types automatically, thanks to the different cleaning modes they come with.
