Flex XCE 10-8 125 vs 3401: A Detailed Comparison 

The Flex XCE 10-8-125 is an updated version of the legendary Flex 3401. Airflow has been optimized in the Flex XCE 8-125 cooling system. Along with this, the system’s new design ensures that the gears are always at a safe temperature and don’t get too hot.

Moreover, the new model comes with both corded and cordless versions, which is always an added benefit. Let’s check what other alterations were made in the newer model –

Power Input:

Before buying any machine polisher it’s very important to check the power input of the machine. A polisher with higher power will be able to remove the painting defects more quickly. 

But at the same time higher power input can be more susceptible to damage to the paintwork. The user must be more careful when using a higher-power input polisher. They also need to be cautious of the car polish they use.

Some car polishes are simply too abrasive to the car and can damage the paintwork when used frequently. You can try the 3D Speed Car Scratch Remover Polish & Wax. It is considered one of the best car polishes that are both economical and effective.

The Flex XCE 10-8-125 (corded & cordless) and Flex XC 3401 both have a 1010-watt power input. This is a considerably higher power input for a machine polisher. If not used carefully both can easily damage the paintwork of your car.

Summary: So, it’s a tie between Flex XCE 10-8-125 and XC 3401 with both having 1010-watt power input.

Power Output:

Flex XCE 10-8-125

You can expect 590-watt power output from Flex XCE 10-8-125 (corded & cordless) and XC 3401. This amount will give you a moderate output force which is sufficient for most polishing work.

You can use these polishers without fear of ruining the paintwork. Removing heavy defects might be difficult with using these two polishers.  But never use these machine polishers to remove silicone from car paint. That might worsen the problem.

Summary: It’s a tie between Flex XCE 10-8-125 and Flex XC 3401 regarding power output as well with 590 watts from both polishers.

Type of  Polisher:

Flex XCE 10-8-125 is a Dual Action Polisher with the power of a rotary polisher. It can easily remove severe paintwork blemishes and can finish with professional detailing. But it may take some time to get used to this machine. If you are not careful while using this you can easily damage the paintwork of your car.

On the other hand, the Flex XC 3401 VRG is a dual-action polisher. This is great for taking out light scratches. You can use this user-friendly machine regularly without worrying about it burning through the paint. Regular use of this machine won’t add any holograms to the paint either. 

Summary: Flex XCE 10-8-125 is a dual-action polisher with rotary power but the Flex XC 3401 is a dual-action polisher. 

Orbit Size:

The orbit size of a machine polisher describes the diameter of the backing plate’s circular motion. The larger the orbit size the more area it will be able to cover with each stroke.

Both flex XCE 10-8-125 (corded & cordless) and XC 3401 have an 8 mm orbit size. This is a great size for removing scratches with precision. Removing fine scratches and getting into tight corners like windows between the truck cab and cap will be easier with this orbit size.

Summary: Both of these polishers have an 8mm orbit size.

Speed Range (No Load):

A machine polisher’s speed range refers to the range of speeds at which the polisher can operate. You can alter the speed of a machine polisher to suit the particular task at hand if it has a wider speed range. A machine polisher with a limited speed range might not be as adaptable.

This is where the XCE and the XC version of the Flex machine polisher differ the most. With no load, the Flex XCE 10-8-125 corded version has a speed range of 140-430 rpm. 

But the cordless version’s starting speed is higher than the corded one.  The cordless version’s speed is around 280-430 rpm. The Flex XC 3401, on the other hand, has a speed range (without load) of 160-480 rpm.

Summary: The Flex XC 3401 has a higher speed range. But with a low starting speed on the XCE, it might be easier to use.

Cable Length:

A longer cable length will allow more flexibility while working. But at the same time, it may be a hassle to manage the longer cable.

Flex XCE 10-8-125 corded version comes with a 13 ft cable whereas the Flex XC 3401 comes with a 25 ft cable. This longer cable of flex XC 3401 will help to reach further spots without using an extension cord. But it can get tangled and can be hard to store.

The Cordless version of Flex XCE 10-8-125 outshines the other two in this section. You can reach tighter spots with this without worrying about the cable getting tangled. But you might need to change the battery from time to time with this. Two 18V 5.0A batteries are included with the Flex XCE 10-8 125 cordless sets.

Summary: Flex XC 3401 comes with a longer cable of 25 ft.


The weight of a machine polisher is always an important factor to consider while buying. Lighter polishers are easier to use. The Flex XCE 10-8-125 weighs around 2.2 kg whereas the Flex XC 3401 weighs slightly more. It is usually around 2.6 kg.

The cordless version of the Flex XCE 10-8-125 might weigh a little more because of the battery size.

Summary: Flex XC 3401 is heavier than the other two.


The Flex XCE 10-8-125 corded is priced between $445 and $450, with the cordless version being slightly more expensive. The cordless version costs between $590 and 620. The Flex XC 3401, on the other hand, costs between $ 465 and $ 470. 

Summary: The Flex XCE 10-8-125  cordless version is more expensive than the other two. 

Flex XCE 10-8-125 vs 3401: Which One to Buy?

Ultimately it depends on you which machine polisher will be preferable. If you’ve been using a machine polisher for some time then the new XCE 10-8-125 won’t be hard to get used to. The XC 3401, on the other hand, has always been a beginner-friendly polisher.

However, the XCE 10-8-125 is significantly lighter and stays cool even when used for extended periods of time. Furthermore, the cordless version is unquestionably an advantage.
