How Long Does Roomba Take To Clean? (Must Know)

The watchword with gadgets or machines is always efficiency. That is something the iRobot Roomba vacuum cleaner certainly offers.

It’s not a humanoid robot that can replace a person, but it does an excellent job cleaning room floors.

The catchy name of this vacuum may leave some people imagining a vacuum robot from a sci-fi movie. But hold your high horse for a moment, and do a reality check.

The makers of Roomba put tremendous effort into the vacuum cleaner. Roomba cleans rooms very efficiently, but there’s a difference between the reality and the high expectations of customers.

One may expect a product tagged iRobot to work magic, but it doesn’t work that way. While Roomba is very reliable, how long it takes to clean depends on various factors. 

How long it takes Roomba to clean rooms depends on the room size. It also matters if there’s a rug in the room because Roomba will spend more time drawing out hair and dust. Your Roomba model also determines the cleaning time. The cleaning cycle for an average room size lasts about 25 minutes. It lasts longer for larger spaces.

How Long Does Roomba Take to Clean a Room?

How long any Roomba cleaning cycle is down to the room size. The units are so efficient they can adapt to cleaning different room sizes.

There is no pre-set dimension for the Roomba vacuum. Instead, it uses infrared technology to estimate the size of any room it’s set to clean.

Then it scans every square foot of the room for dirt and dust to clean them up.

Most Roomba vacuum cleaners can clean without human aid. After you press the ‘clean’ button on Roomba, you can leave it to do its thing.

When the cleaning cycle is complete, Roomba returns to base on its own. That’s pretty neat.

The cleaning cycle for an average room size lasts about 25 minutes. By average room size, we mean rooms that measure at least 224 square feet.

For a further breakdown of the cleaning cycle length, Roomba spends roughly 1 minute per 9 square feet.

That statistic reveals a good measure of efficiency. Also, considering that Roomba does an excellent cleaning job.

The Roomba battery life also determines how long cleaning cycles last. The efficiency drops with reduced power.

So, you will always get the best cleaning time when your Roomba has a full battery charge. Cleaning will also last longer if you charge your Roomba vacuum during the cycle.

Room flooring affects the length of Roomba cleaning cycles a great deal. For example, if your room has a rug, Roomba will take more time than usual to clean dirt.

That is because it’ll have to attend to more dust and dirt on the rug. So, Roomba’s cleaning time for two rooms of the same size will differ if one has a rug.

Objects in the room also affect the length of a cleaning cycle. Some Roomba models have object avoidance technology.

So, it’s easier for them to work around obstacles. Models that lack the technology spend time meant for cleaning and avoiding obstacles in the room.

Don’t expect the time Roomba takes to clean a room to increase precisely as the room size increases.

Roomba’s efficiency ensures that it always gives the best results within the shortest possible time.

How Long Does It Take for an iRobot Roomba to Clean 500 Square Feet?

Barring any obstacles in a 500 square feet space, Roomba can take up to 90 minutes to clean.

When using Roomba to clean 500 square feet, one full battery charge is enough for the cycle.

So, regardless of the Roomba model, you don’t have to bother about charging in-between cycles.

But you may rethink that if the room has many obstacles and packs a lot of dirt.

Roomba exerts more power when it has lots of work to do. Therefore, Roomba will spend more time and battery charge when there’s a lot of dirt in the room.

In essence, the length of average cleaning cycles applies to spaces with few obstacles. So, don’t expect Roomba to finish cleaning in record time if you have a lot of stuff.

That said, Roomba will complete the cleaning cycle for 500 square feet based on the setup of the space.

So it’ll spend the least time cleaning the space when there are fewer obstacles and dirt. But the cleaning cycle will be considerably longer if conditions differ.

How Long Does It Take Roomba to Clean 1000 Square Feet?

It can take up to 2 hours for a Roomba model to clean 1000 square feet. So if the model has a runtime of under 2 hours, it’ll need a recharge before it can complete the cleaning cycle. 

For spaces over the average size, the Roomba model and battery life are significant factors during cycles.

If the battery runs down midway through a cycle, Roomba returns to base to recharge. For some models, you must pick the Roomba and move it to the charging base.

So, the charging time adds to the total time Roomba will take to complete a cleaning cycle.

A space that measures 1000 square feet is many times over average. So, you must consider the Roomba battery life at this point.

Some models would need a recharge in-between the cleaning cycle before covering 1000 square feet.

That means you’ll get shorter cleaning cycles with long-lasting Roomba batteries.

The Roomba 690, for example, has a runtime of 90 minutes. So it’ll take 2-3 hours of charging added to the cleaning time.

You can clean 1000 square feet on one full charge with Roomba models like 960 and i7.

But as always, the exact time for a model depends on obstacles and dirt in the 1000-square foot space.

Why Does My Roomba Take So Long to Clean?

There are two things you should watch out for; dirt and obstacles. These two factors affect how long any Roomba cleaning cycle lasts, regardless of the room size.

Roomba’s design ensures that it cleans every part of the floor thoroughly. The dirt detection technology is responsible for that action.

So, as long as Roomba detects dirt in an area, it’ll vacuum until it doesn’t.

Roomba will also spend time maneuvering obstacles in a space it’s cleaning. While it’s most times good at clearing an obstacle course, Roomba spends time meant for cleaning doing that.

So, they’ll slow Roomba down if you have lots of furniture or equipment. A rug is also something that keeps Roomba busy.

Rugs pack a lot of dirt and hide them pretty well. So, Roomba will vacuum a rug until it doesn’t detect any dirt.

But, if obstacles and dirt loads aren’t the problem, it may be down to a poor Wi-Fi connection.

That is, for models that can work with Wi-Fi. They depend on wireless transmission of data to function efficiently.

If there’s a drag with data, Roomba will take more time than usual to execute functions. So, ensure the Wi-Fi network is at its best, and Roomba will do the rest.

Some Roomba models have an intelligent mapping feature. The feature helps Roomba vacuum cleaners know their way around a house.

So, they can access a building’s floor plan and use it to move without a hiccup. Smart mapping helps when Roomba has to clean larger spaces – upwards of 1000 square feet.

What Is the Best iRobot Roomba to Get for a Big House?

For large spaces, it’s best to go for models with long-lasting Roomba batteries and the latest intelligent features.

But as you know, all high-end gadgets don’t come cheap. But not to worry, we have a solution for you.

We have two Roomba models that are a perfect fit for large homes. One is pocket-friendly, and the other might put a dent in it.

Conclusion

Roomba vacuum cleaners are arguably the best robotic vacuums on the market. Cleaning cycles usually last 25 minutes for average room sizes.

But, it can exceed 2 hours for larger spaces. Dirt and obstacles can also add to the cleaning time.

Also, if the Roomba model has a short battery life, you’ll need to charge in-between cycles.
