What is Roomba?

Robotic vacuums are completing the responsibility of cleaning the floors of our houses nowadays pretty well. Roomba is a robot vacuum series with various models produced and sold by the brand named iRobot. In the early 2000s, iRobot introduced this intelligent floor cleaning vacuum series in the market.

The vacuums from this Roomba series come with different sensors to navigate the floor area. In addition, you can command the Roomba with your voice or preset the cleaning area if you are not supposed to be at home. There is also an option for customizability and reprogramming in the vacuums of this Roomba series.

Are Robot Vacuums Good on Thick Carpet?

The robot vacuums can make your household task easier by cleaning your floors whenever required. These intelligent floor cleaners can be operated both manually, and with voice commands. But all the robot vacuums won’t be able to operate properly on the floors that are covered with carpet.

So, when it comes to the thickly carpeted floors, you will have to go for the robot vacuums that are capable of the job. Most of the Roomba series from the iRobot brand is built to clean dust and dirt from the thick carpets. These robot vacuum cleaners are built to clean around your busy schedule and lessen the hassle.

Compared to a typical floor, the thickly carpeted floors are hard to clean for the regular robot vacuums. In this case, a vacuum with high-pressure taking capability is a must. Vacuuming a carpet takes longer than hardwood floors, so you need to go for the vacuums with long battery life.

The vacuums with at least 100 minutes of battery life are necessary for the carpet cleaning task. The robot vacuums also need to be rated for the plushest and high-pile carpets for carpet cleaning. At the same time, you must seek the vacuums that are rated well for pet hair and other hairy dust.

Durability is also an essential factor for the robot vacuums for cleaning more challenging surfaces like thick carpets. Unfortunately, not all robot vacuum cleaners have all these capabilities. Though you can clean the carpet with any random robot vacuum cleaner, the result will not be even closer to what you have expected.

But, most Roomba vacuums come with all these crucial features required to clean the thick carpet floors. These vacuums will clean the dirty carpet of your house according to your command, no matter how thick the carpet is.
