Cordless vs. robot vacuums: which one should you buy?

When it comes to keeping your floors clean, robot vacuums and cordless vacuums are among the best products you can buy. Robot vacuums have become increasingly popular over the past few years — thanks to premium models like the Ecovacs X2 Omni and Roborock S8 Pro Ultra — but cordless vacuums offer plenty of advantages over their robotic counterparts.

Deciding between the two isn’t easy, and thankfully, it’s hard to make a wrong decision. Both are well-equipped to clean your floors, but there are some big trade-offs you’ll have to make for each class. So, which is better? Robot vacuums or cordless vacuums?

Here’s a closer look to help you decide which is best for your smart home.

Cordless vacuums offer a better cleaning

Robot vacuums have made massive strides, but there’s no denying that cordless vacuums typically provide you with a better cleaning experience. Their larger size allows them to produce impressive suction and airflow numbers, enabling them to pull up all sorts of debris from your carpets. They also tend to come with additional attachments so that you can clean furniture or nooks and crannies throughout your home.

Many robot vacuums advertise impressive suction numbers, but they can’t match the cleaning prowess of cordless vacuums. Of course, this can vary widely based on specific models, but cordless vacuums generally provide you with a more robust cleaning experience than robot vacuums.

Robot vacuums are more convenient

There’s something to be said for coming home to a house that’s already been vacuumed. The big appeal of robot vacuums is that they’re essentially an extra pair of hands — once you’ve gone through the mapping process and set up a schedule, they’ll clean your home without any additional input. If you’re constantly finding yourself forgetting to vacuum or tied up with other chores, adding a robot vacuum to your house is a great decision.

Cordless vacuums are starting to make strides in this area, with premium products now designed with built-in dustbins. After you’re done with your cleaning, placing the cordless vacuum in its dock will automatically empty its dustbin into an attached reservoir. This isn’t nearly as much automation as you’ll find in robot vacuums — but at least it helps keep your hands clean.

Cordless vacuums are more affordable

All the fancy tech packed into robot vacuums makes them shockingly expensive. Premium models often carry price tags well above $1,000, whereas you can snag a great cordless vacuum for less than $500. That’s a pretty massive price difference, so if budget is a big concern, cordless vacuums are a better pick. You can certainly find robot vacuums for less than $500, but they may not be as automated as you’d like (meaning you’ll still need to interact with them after each cleaning cycle).

Robot vacuums can also mop

If you’re looking at the best robot vacuums, you’ll notice many of them double as mops. Not only will they automatically mop your hardwood floors, but they’ll retract their mops when traveling on carpet, allowing them to vacuum and mop in a single run. This can save a lot of time for homes with multiple types of flooring.

Of course, it’s possible to find cordless vacuum/mops, but most of them are hard to recommend due to their less-than-stellar performance. Meanwhile, robot vacuum and mop combos tend to perform both tasks reasonably well without sacrificing one for the other.

Cordless vacuums are better for a quick clean

Most robot vacuums take a long time to sweep up your floors. An area that takes around 15 minutes to handle with a cordless vacuum takes nearly twice as long for my Ecovacs X2 Omni and Roomba Combo j9+. Robot vacuums are also creatures of habit, meaning they’re best used to clean the same areas repeatedly. For example, many users will program their robot to clean their living space several times a week, with little variation between cycles.

A cordless vacuum, by contrast, can be used to clean smaller, more confined areas without hassle. Simply disconnect it from its charging station, sweep up the area that needs attention, and then place it back in its dock. This makes them great at handling one-off cleanings, such as when dirt gets in your entryway or if you spill food crumbs on the carpet.

It’s possible to tackle these problems with most robot vacuums, but you’ll either need to open up your app and program in a new cleaning location or take manual control of the device like an R/C car (both of which are time-consuming).

Is a robot vacuum better than a cordless vacuum?

Robot vacuums and cordless vacuums are both excellent products, but neither is better than the other. While they’re both designed to keep your floors clean, that’s where the similarities end.

Cordless vacuums are ideal for homes that need a superior clean and for folks who don’t mind tackling the task manually. Robot vacuums are for homeowners content with an automated clean — even if it isn’t the best clean possible. Consider picking up a robot vacuum if you’re looking to free up time in your schedule and a cordless vacuum if you need a superior cleaning experience.

Oddly enough, many homes bundle the two products together to keep their floors as pristine as possible. For example, you can run your robot vacuum three times a week, then perform a manual cleaning with a cordless vacuum on the weekends. This makes it easy to eliminate pet fur and allergens lurking in your carpets, and is especially ideal for households with several children (or pets) roaming around the halls.

Ecovacs reveals robot vacuum with new technology ideal for carpeted homes

Ecovacs just launched the Deebot X8 Pro Omni in February, which we found to be an excellent choice for hard floors -- thanks to its innovative roller mop that tackles all sorts of spills with ease. For March, it looks like the focus is on carpets, with the newly launched Ecovacs Deebot T50 Max Pro Omni incorporating new technology designed to better extract debris from plush floors.

The Ecovacs T50 Max Pro Omni is the first Ecovacs product to use BLAST Technology. An acronym for Boosted Large-Airflow Suction Technology, the new system uses both suction and optimized airflow to better pull debris, dust, and pet hair from deep within carpet fibers. Using a high-toque 100W motor, Ecovacs says the robot can achieve a 50% higher discharge current while generating 50% less heat than traditional robot vacuums. In other words, it's built to have a longer lifespan while also providing you with a superior carpet cleaning experience.

The Roborock Saros 10 and Saros 10R are two of the best robot vacuums on the market. Capable of mopping, vacuuming, and automatically cleaning themselves, they can go weeks without requiring any manual input. However, like all electronics, they’re not free from issues. And though we didn't run into any serious issues during our testing, a handful of users are reporting minor errors with their products. Thankfully, these are usually quick fixes -- with just a few minutes of maintenance, your Roborock will be back in working order.

Running into any issues with your robot vacuum? Here’s a look at the most common errors on the Roborock Saros 10 and how to fix them. Note that these tips will also work for the Saros 10R.
How to fix Error 5
This error relates to the main brush of the robot. To resolve the problem, make sure the brush isn’t caught on anything and that nothing is blocking it from spinning. This includes removing the brush from the robot and checking its installation chamber, as debris and hair can get trapped inside. Once you’ve cleared out any debris, the error should fix itself.

iRobot reveals gigantic lineup of affordable Roomba robot vacuums
All the upcoming Roomba robots on display

iRobot is one of the most popular manufacturers of robot vacuums, and its lineup is about to grow much more enticing. Several new models will be up for presale on March 18 -- all of which feature prices under $1,000. That makes them affordable alternatives to expensive options like the Roomba Combo 10 Max or Roborock Saros 10R, both of which carry hefty price tags of around $1,500. This is the largest product launch in the history of iRobot (featuring eight products), and it’s designed to offer a solution for every budget.

The most expensive of the bunch is the Roomba Plus 505 Combo Robot + AutoWash Dock. Designed with dual rotating mop pads that can swing outward, 70 times more suction than the older Roomba 600 series, and a LiDAR system that should deftly maneuver your home day or night, it looks like a well-equipped robot for $999.
