Improvements in technology have made things possible that would have appeared impossible just a few years ago. For example, robots have now become practical alternatives for a number of duties. They are able to work unsupervised and achieve results that are as good as, if not better, than what we would have achieved doing the work ourselves.

Robot vacuum cleaners are by far the most popular household robots globally. They were among the first to be built and adopted widely in households all over the world. These devices are compact, functional and very convenient.

The main barrier that has kept many people away from these devices has been their high price tags, but with the introduction of some low-cost options that perform a decent cleaning job, this is no longer the case.

However, even with all the many options available, it is important that you pick a vacuum cleaner that will work best in your particular situation. There are models specifically made to tackle different surfaces.

For example, there are models that will work best on hard floors while there are others that will perform better on carpets. If you have pets, pick one that will not have a problem sucking up pet hair and dander.

Buying Guide

We have already mentioned that thick carpets can be hard nuts to crack for most vacuum cleaners. To ensure that you choose a device that will get the work done, here are a number of things to look out for:

Large Wheels

Most homes with thick carpets don’t have the carpets covering the entire floor surface. This means that there will be a point where the carpeted surface ends and the rest of the surface starts. Since robot vacuum cleaners manage their own cleaning patters, this transition needs to be something they can comfortably make.

Large wheels will help the robot to easily climb up into the carpet and back down as the need arises. Large wheels also make it easy for the vacuum to move around on the carpet fabric despite the large fibers. You don’t want the wheels to get tangled on the fibers as the vacuum moves over the carpet.

Strong Suction

The thick fibers on the carpet are comfortable when you are walking on it, but they are a totally different nightmare when the time comes for cleaning. This thickness provides more hiding spaces where dirt and debris can hide from vacuum cleaners.

To be able to remove all the particles from between the fibers effectively, a vacuum cleaner will need to have a strong suction power that reaches far into the carpet fibers. Start your search with the models listed below that have been proven to deliver strong suction.

Turbo Boost

Turbo boost is a feature that steps up the vacuum to get all the dirt out of difficult environments. This will be particularly useful in thick carpets because they need more suction. Different models call this feature different names, but the principle is the same. The important thing to look out for is some way of boosting the suction power from the device.

Robot Vacuum for Carpet


In addition to sucking up particles from the floor, robot vacuums have to try and dislodge any particles that are stuck on the floor surface. This is achieved by the use of rubber or bristle brushes that rotate underneath the robot.

Some models have two brushes that rotate in opposite direction to pick up the particles after they have been dislodged from the floor surface. Good brushes make work easier for the vacuum because the particles will be easy to suck once they have been beaten by the brush.

What's the best robot vacuum for carpet?

Floor Mapping

Floor mapping helps the vacuum better understand the area that it needs to vacuum so that it can come up with an efficient cleaning pattern. This will ensure that cleaning is completed faster hence a lower chance of running out of charge.

This is very important in thick carpets because the high suction required to clean them consumes higher battery power than normal.

Floor Surface Detector

This will feature will be more important to you if you have different floor types in your home. Thick carpets need more suction than hardwood and other hard surfaces. A robot that detects the type of floor will be able to adjust the settings accordingly so that every floor surface gets the best possible clean.

This means boosting suction when it reaches carpets and lowering it for hardwood and other such floors.

Are robot vacuums good on carpet?


Why do thick carpets need special cleaning?

Vacuum cleaners were invented for carpets. Without them, keeping carpets clean would have been a very difficult chore. Thanks to the invention of these devices, we can enjoy a nice, comfortable and clean floor surface.

Despite being even more comfortable than standard carpets, thick carpets can be hard to clean. The long fibers that feel good on your feet are also perfect hiding spots for dirt and debris. Vacuum cleaners will need to work extra hard to get all this dirt out of the carpets.

This is why you need to make sure that you buy a vacuum cleaner that will be able to handle the hard work of getting embedded particles out of the carpet.
