When it comes to cleaning up your home, automobile, or workspace, sometimes a standard vacuum doesn’t cut. In places where messes are especially unpredictable, having a vacuum that can take on a multitude of tough jobs is incredibly important. Vacuums that are able to take on both wet messes and dry messes are handy appliances that most users can’t live without. Finding the right wet/dry vac will truly change the way you keep your spaces clean.

The Armor All AA255, Shop-Vac 2021000, and Vacmaster VP205 are all wet/dry vacs that are similar in price point and design. Because they are so similar, it can be difficult for consumers to know which model will be the right fit for their desired uses. Comparing them to several different areas allows us to break down their features and determine which is the best overall device.


Wet/Dry vacuums are nothing if they are not functional. Although all three models are designed to clean up both wet and dry messes with strong suction power, they have slightly differing functionality. The Armor All AA255 and the Vacmaster VP205 both feature an auto shut-off feature that prevents overflow when in use. Both of these models also convert to a blower, making it easy to clear debris, dry cars, and inflate pool toys when necessary.

While the Shop-Vac 2021000 is meant to be an all-purpose cleaning device, it lacks these convenient extra features. It can quickly tackle both wet and dry messes in your home or workshop. However, when it comes to increased functionality, this device tends to fall short when compared to the other models.

For the most functional wet/dry vac, the Armor All AA255 and the Vacmaster VP205 are nearly identical. They both are great devices to have on hand, as they have superior suction power as well as extras that set them apart.

Design & Capacity

While similar in design, their capacity and intended functioning are where these devices begin to differ. The Shop-Vac 2021000 features a 1-gallon storage tank and a 1-horsepower motor. An incredibly compact device, it is ideal for sudden, unexpected spills. It can handle small messes with ease.

The Armor All AA255 and the Vacmaster VP205 are larger and more thoughtfully designed devices. They each boast 2.5-gallon storage tanks and 2-horsepower motor, making them twice as powerful as their competitor.

Because these vacuums have an impressive storage tank, you’ll find yourself emptying them at a less frequent rate. Their motors are also twice as powerful as the one seen in the Shop-Vac 2021000

When it comes to overall design and capacity, it’s clear that once again, the Armor All AA255 and the Vacmaster VP205 are our top picks. Not only are they more powerful, but they also allow for increased cleaning time and capacity. Nearly identical in this category, both of these models prove to be superior.

Storage & Portability

Unlike other vacuums, wet/dry vacuums need to be incredibly portable to eliminate hard-to-reach messes and take on irregular surfaces like car interiors. Weighing in at 7 pounds, the Armor All AA255 has a top handle which allows for a convenient carry.

There is also onboard storage on the lid for cleaning accessories, meaning the attachments can accompany you with ease. The Vacmaster VP205 also has these features, however, is slightly heavier at 8-pounds overall.

At 5 pounds, the Shop-Vac 2021000 is the lightest model. It also has a convenient carrying handle and an accessory bag for keeping all of your tools organized. Where this device truly shines is its wall mountable feature. Being able to mount this vacuum on your wall makes it incredibly handy and readily available when you need it most. The 6-foot power cord also means you’ll spend more time cleaning and less time searching for an outlet.

While all of these devices weight less than 10 pounds and have top handles for increased portability, the Shop-Vac 2021000 is superior when it comes to portability and storage. Included wall mounts mean that you can permanently keep this vacuum in a location most convenient for use.

Additional Features

Additional features and extra attachments are what set these devices apart. The Vacmaster VP205 features an included 2-in-1 utility nozzle and a crevice tool for reaching small or difficult to clean spaces. The Armor All AA255 also features both of these attachments, as well as a deluxe car nozzle and detail brush for creating a clean interior when it comes to your automobile.

The Shop-Vac 2021000 cannot say the same. While it includes a crevice tool, it’s only other attachment is a gulper nozzle for fast and effective pickup. It does also include a tool bag for storage and a wall bracket for easy wall-mounting. However, its cleaning accessories are slightly lacking when compared to the other two models.

In this area, our pick for the wet/dry vacuum with the most impressive additional features is the Armor All AA255. Not only does it include a variety of attachments that put its power to use, but it also features an automatic noise diffuser that effectively minimizes the volume of this device. Use this in your car, workshop, home, or office without affecting anyone around you.

Armor vs Shop-Vac vs Vacmaster: Conclusion

The Armor All AA255, Shop-Vac 2021000, and Vacmaster VP205 are all powerful vacuums that are able to take on messes of all kinds with ease. The Shop-Vac 2021000, however, has not only the least amount of power but also the smallest capacity.

While incredibly lightweight and portable, this increased portability comes at the cost of power and effectiveness. Featuring a wall mount, it is better for small jobs or as a second device to have on hand in case of emergencies.

While the Armor All AA255 and the Vacmaster VP205 are nearly identical devices, the Armor All AA255 has a slight edge. Designed with impressive capabilities, functionality, and a variety of extra features, it will take on any mess anywhere. Perfect for detailing the interior of your car – and more – the Armor All AA255 is our overall pick for the best wet/dry vacuum.
