Wen 6369 vs 6377 | Battle of the Drywall Sanders

Are you in the market for a drywall sander? Deciding between the Wen 6369 and the 6377 can be difficult and tedious due to the products’ similarities. They have a swiveling head with a speed of 600 to 2500 rpm, an automatic dust removal system and a 5-amp motor.

Still, there are differences you should be aware of. Write a list of your interests and compare them to competing tools. This article will give you an overview of each grinder, its advantages and disadvantages, how to use it and its functions.

Wen 6369

Wen 6369 has a variable speed adjustment feature that operates from 600 to 1500 RPM. The hook-and-loop base pad makes changing sandpaper easier. It features a 5-Amp head-mounted motor for maximum torque to the sanding disk. 

For an effective dust removal system, you have an automatic system combined with the 15-foot dust hose minimizing clean-up. You will not have to spend much time cleaning during and after your project. The package includes 60, 80, 120, 150, 180, and 240-grit hook-and-loop 9-inch sanding discs.

What determines the time taken is the grit number and sandpaper brand you use. The lower the number, the bigger the grit, and the faster it takes. However, you are more likely to have scratches on your material. The smaller the grit, the slower it goes, leaving a smoother finish. You may start with a larger grit and finish with a smoother one. 

Although it is lightweight, try not to hold it up to the ceiling for long. Even though it has an adjustable handle and strap, it is not easy for a shorter person. Use a ladder to redistribute the weight. You might struggle to locate the on-off switch unless you get used to it. A different color on the handle would have been better to mark it easily. If you are in a hurry, you might spend more time figuring it out.

The 8.5″ head swivels in all directions, making adjustments automatic. It becomes versatile to get into any surface, including tight corners and ceilings.

Automatic Dust Removal

You do not have to clean up after a busy day on your project. Messy workspaces slow down your progress. The dust vacuum hose is flexible enough to stretch up to 15 feet for reliable dust removal.

Variable Speed Motor

The variable speed dial adjusts 600 to 1500 RPM, while the 5-amp head-mounted motor design maximizes torque during operation. The motor on the head is a bit top-heavy, but with time, you get used to it.

Dust vacuum hose

It features a 5-amp head-mounted motor that provides maximum torque to the sanding disk.

Feature comparison


When you first look at these tools, you can hardly notice the difference. The 6369 drywall sander is more comfortable than you expect, as it causes less hand fatigue. Hence, we will give the winner title in mobility to this tool.


The motor power shows off a strong resemblance between these two tools. Both of them feature a 5 Amp, 120 V head-mounted engine to maximise the torque to the disk. That is how they manage to tackle projects with ease. You can operate two WEN products on a variety of materials. 


WEN 6369 is 9.2 pounds, whereas the 6377 is 7.26 pounds heavier.

What could be better

Wen 6369

  • Improve the speed control and on/off. The sanding machine would have been allowed to stop while the sanding pad is against the surface so the dust would not escape.
  • The on/off switch should not be in an area where your hand often goes, which is why it shuts off a few times while using.
  • A longer cord would have been better.

Wen 6377

  • The hose could have been lighter.
  • The On/Off switch could have been in a convenient location and easy to reach.
  • Maximum removal of dust would do. 

Similar Features

  • They operate at the same speed variance of 600 to 1500 rpm. 
  • Both have a 5-Amp motor.
  • They have sanding discs of the same size.
  • They are heavy. 
  • Both have an automatic dust removal system with the dust hose stretching up to 15 feet. 
  • They have a pivoting head meant to swivel in all directions.
  • Their sanding discs are available in 6 different grits.

Key Differences between WEN 6377 and WEN 6369

  • WEN 6377 is more impressive than the 6369 because of its exclusive feature.
  • Wen 6377 has added two hook-and-loop sanding heads, including triangular and circular ones, making it easy to swap on the desired pad shape, depending on the demands of your task.

The verdict

In summation, the above tools are almost identical but have differences that keep them separate. If you want a sanding machine for a homeowner looking to ditch their popcorn ceilings, Wen 6369 might be your perfect pick. For a more impressive drywall sander, WEN 6377 is ideal. I assume you have made your decision based on the above reviews.
