Are you contemplating buying a robot vacuum for your home? If so, the first question you should ask yourself is, how long does it take for a robot vacuum to clean a room? Of course, buying a robot vacuum is one of the best decisions you could ever make, since it will save you a lot of time and effort when it comes to cleaning the house.

Robot Vacuum

Even so, you don’t want a robot that takes forever to clean your home. Similarly, you wouldn’t want to buy a vacuum that cleans within a short time, but leaves behind debris and lots of dust. In this article, we discuss how long a high-quality robot vacuum takes to clean a room effectively and how different models of vacuums compare when it comes to the speed of cleaning.


How Long Does It Take for a Robot Vacuum to Clean a Room?

A fully-charged Roomba vacuum cleaner takes about 1-2 hours to clean a standard room size of 2,000 square foot. Most other robot vacuum cleaners take about 90 minutes or more to clean a room of the same size. However, the amount of time that the vacuum cleaner takes to clean is usually determined by a number of factors, such as the floor type (carpet, tiles or hardwood), type and model of the vacuum, floor size, home layout, battery capacity, as well as the amount of furniture in the room. All these factors significantly affect the time the robot vacuum takes to clean a room.

How Long Does Each Roomba Model Take to Clean?

As mentioned in the above subheading, the amount of time that a robot vacuum takes to clean a room is usually determined by its model and type. Consider the following seven common models of the Roomba vacuum cleaner and how long each model takes to clean:


1. Roomba 805

If used to clean a space with a mix of hardwood and carpet flooring, the Roomba 805 model would clean an area of 300 square feet for about one hour. And when the battery runs low, the vacuum cleaner would return to its charging dock and recharge for 2 hours. Once fully charged, you can then restart the vacuum manually to resume cleaning.


2. Roomba 675

With a battery run time of ninety minutes, the Roomba 675 vacuum can clean 500 square feet of cleanable space without running out of charge. When the battery is depleted, the vacuum docks in its charging station, where it charges for 2-3 hours.

After recharging, the machine can then resume cleaning if it had not managed to clean everything well before the battery depleted. The vacuum can either use the WiFi-connected Home app or wait for you to start it up manually.


3. Roomba 614

The Roomba 614 has a battery limit of 90 minutes. Within these 90 minutes, it can effectively clean carpet, tiles and hardwood flooring of about 500 square feet. When the battery is almost drained, the robot vacuum finds its way to the charging dock. After it is fully charged, you can then send the vacuum back manually or via its scheduled cleaning to finish up its work.

4. Roomba E5 (5150)

This model has a battery run time of 90 minutes, which gives it enough power to clean about 600 square feet of cleanable house area. Once the vacuum cleaner gets the job done or runs low on battery, it returns to its charging dock automatically for recharging. The vacuum also sends you a notification about its movements.


5. Roomba 670

The Roomba 670 has a run time of 90 minutes. It can clean a space of approximately 500 square feet. The only downside about this robot vacuum is that it does not have the recharge-and-resume ability like most other similar vacuums. Rather, when the battery begins running low, the vacuum docks in the charging station, where it charges for about 2 hours.


6. Roomba 690

The Roomba 690 vacuum is ideal for cleaning homes with toddlers, dogs, infants and other pets. It usually cleans 500 square feet of space within 90 minutes. The vacuum includes a Dirt Detect feature that guides it on which areas to clean. When the battery runs low, or after each cleaning cycle, the vacuum cleaner will return to its charging station.


7. Roomba 671

This particular vacuum cleaner has a 90-minute battery run time. It cleans approximately 500 square feet of both carpet and hardwood flooring. However, the Roomba 671 has a random cleaning pattern. When the battery runs low, it finds its charging dork and recharges for about 2 hours while waiting for cleaning instructions.



Considering how long does it take for a robot vacuum to clean a room can help you choose the best vacuum for your home. Keep in mind that different models have different battery run time and speeds. Therefore, when buying a robot vacuum, make sure that you choose one which works effectively on your type of flooring and cleans well within a reasonable amount of time.
