Cleaning car interiors, workshop sawdust, or liquid spills often calls for a compact vacuum that does not take up precious garage space. The Armor All® AA155 Wet/Dry Vacuum packs a 2 Peak HP motor and a 1.5-gallon canister into a 4.6-pound frame. While its lightweight housing and wall-mount design offer high convenience, its compact tank size and noise output present specific tradeoffs. This review breaks down suction performance, build quality, usability, and real-world value to help you decide if it fits your detailing routine.
Quick Verdict
Rating: 8.2/10 (Recommended for Car Detailing & Small Workspaces)
Best For: Car owners, apartment dwellers, and hobbyists needing a highly portable wet/dry vacuum for light garage and auto cleanup.
Bottom Line: The Armor All AA155 delivers surprisingly strong suction power and blower versatility in an ultra-portable 4.6 lb frame. However, its 1.5-gallon tank fills quickly during large wet messes, and its 80 dB motor operates loudly in small spaces.

What Is the Armor All AA155 Vacuum?
The Armor All® AA155 is a utility wet/dry vacuum engineered specifically for targeted cleanups in tight spaces, vehicles, and small work areas. Powered by a 2 Peak HP motor, it bridges the gap between weak handheld vacuums and bulky full-size shop vacuums. Its 1.5-gallon poly canister is lightweight yet sturdy, resisting corrosion from damp debris and liquid pick-up.
Weighing just 4.6 pounds and measuring 9.1 x 7.9 x 11.5 inches, the AA155 focuses heavily on portability. A top handle keeps the machine balanced when carried, while the included wall mounting bracket allows you to store the vacuum off the floor when not in use. Additionally, the unit converts into a blower by connecting the hose to the air exhaust port, making it useful for clearing dry leaves or blowing dust out of tight car crevices.
Who Should Buy It?
Best For
- Vehicle owners who need dedicated car interior detailing power.
- Garage and workshop DIYers tackling light sawdust, dry debris, or minor spills.
- Homeowners with limited storage space who prefer wall-mounted utility tools.
Skip If
- You require a heavy-duty shop vacuum to clean up major construction debris or large floor areas.
- You need a quiet vacuum for late-night indoor residential cleaning.
- You want a cordless battery-powered unit for cleaning without electrical wall outlets.
Before You Buy: The Armor All AA155 is a corded utility vacuum that requires a standard 120V wall outlet or extension cord. Its 1.5-gallon capacity is optimized for spot cleaning and vehicle footwells rather than draining flooded basements or vacuuming large home carpets.
Key Features of the Armor All AA155
Suction Power and Blower Functionality
The core strength of the AA155 lies in its 2 Peak HP motor. While modest compared to 5 HP contractor vacuums, it provides substantial suction lift for a vacuum under 5 pounds. It easily picks up ground-in dirt, gravel, dry leaves, and pet hair from automotive carpets. Swapping the 4-foot hose to the rear exhaust port converts the unit into a focused air blower. This air stream is ideal for blowing dust out of dashboard vents, cleaning workbench corners, or clearing leaves from your driveway edge.
Compact Build, Portability, and Wall Mounting
At 4.6 pounds, carrying the vacuum around a car or climbing garage steps requires minimal effort. The top carrying handle keeps the unit balanced during transport. Storage is equally straightforward: the package includes a wall mounting bracket that securely holds the vacuum off your garage floor. Furthermore, integrated storage slots on the powerhead hold up to six accessories, keeping nozzles and extensions organized in one place.
Noise Levels and Operational Considerations
At peak operation, the AA155 generates approximately 80 decibels of sound. This noise level is typical for compact high-RPM shop vacuum motors, but it is noticeably loud inside enclosed vehicles or small utility rooms. Wearing hearing protection during extended cleaning sessions helps maintain comfort.
Pro Tip: When switching from dry dirt to liquid spill cleanup, remove the dry paper filter and install the foam sleeve filter to protect the motor from moisture damage and maintain maximum airflow.
How It Performs in Real Use
Car Detailing and Vehicle Interior Cleaning
The AA155 excels at automotive maintenance. The 4-foot flexible hose combined with crevice tools allows you to reach beneath seats, clean floor mat seams, and clear out cup holders. Its suction effectively extracts sand and dry mud that standard cordless hand vacuums leave behind.
Workshop and DIY Debris Cleanup
On workbenches and around power tools, the 1.5-gallon tank easily collects sawdust, wood shavings, and drywall dust. The compact footprint means you can place the vacuum directly on a workbench without overcrowding your workspace.
Liquid Spills and Damp Messes
For minor plumbing drips or wet floor mats, the wet suction mode safely draws water into the poly tank. Because the tank holds 1.5 gallons, you will need to empty it frequently during moderate liquid spills, but for quick emergency cleanup, it works reliably.
Maintenance and Safety Guidelines
To ensure optimal suction and prolong motor life, clean or inspect the internal filter regularly. Empty the poly tank after wet cleaning to prevent mold, odors, and mineral buildup. Always disconnect the power cord before removing the motor housing or changing filters. Avoid vacuuming flammable liquids, hot ashes, or fine toxic powders without appropriate high-efficiency filter media.
Pros and Cons
Pros
- Impressive 2 Peak HP suction for a lightweight 4.6-pound vacuum.
- Dual wet/dry functionality plus a convenient rear blower port.
- Includes wall mount bracket and on-board storage for 6 accessories.
- Compact footprint fits easily on garage shelves or workbenches.
Cons
- 1.5-gallon capacity requires frequent emptying during larger jobs.
- Motor operates at 80 dB, which can feel loud in tight spaces.
- Short 4-foot hose requires moving the main unit frequently around larger vehicles.
Is It Worth the Price?
The Armor All AA155 sits in an affordable budget utility category. Considering it offers a 2 Peak HP motor, blower capability, wall bracket, and integrated accessory storage, it delivers strong value for buyers who want an organized, dedicated garage tool.
If you primarily need a portable vac for vehicle detailing or minor workshop dust, it offers a cost-effective alternative to full-sized shop vacuums. However, if your projects regularly involve heavy contractor cleanup or whole-house carpet vacuuming, investing in a larger 5-to-6 gallon vacuum will better suit your needs.
How It Compares to Alternatives
Compared to standard cordless hand vacuums, the Armor All AA155 provides significantly stronger suction power and consistent corded runtime, though it requires access to an electrical outlet. When compared to larger 5-gallon wet/dry vacuums from Craftsman or Stanley, the AA155 is far lighter and easier to store, but has a smaller tank capacity and a shorter 4-foot hose. It hits a sweet spot for targeted car detailing and space-conscious garage storage.
Frequently Asked Questions
Can the Armor All AA155 handle pet hair effectively?
Yes. The 2 Peak HP motor generates strong suction that lifts embedded pet hair from automotive upholstery and trunk carpets, especially when paired with a detail nozzle or utility brush attachment.
Is the Armor All AA155 corded or battery-powered?
The AA155 is a corded electric vacuum powered by a standard 120V household AC wall outlet. It does not use a rechargeable battery, ensuring consistent suction power without battery drain issues during cleaning sessions.
What surfaces can this wet/dry vacuum clean?
The AA155 effectively cleans automotive carpets, hard floor surfaces, upholstered car seats, workshop tables, and concrete garage floors. It handles dry dirt, sawdust, and liquid spills with ease.
How do you convert the AA155 into a blower?
To use the blower feature, disconnect the hose from the front suction intake port and attach it securely to the air exhaust port located on the back of the motor housing.
Are replacement filters readily available for the AA155?
Yes, replacement foam filters for wet pick-up and reusable cloth/paper filters for dry dust are widely available online and at major auto parts retailers. Regular cleaning or replacement maintains suction efficiency.
How does the wall mount bracket work?
The included wall mounting bracket screws directly into garage wall studs or drywall anchors. The vacuum locks securely onto the bracket when stored, keeping it elevated and off your garage floor.
The Bottom Line
The Armor All® AA155 Wet/Dry Vacuum proves that compact tools can still deliver serious cleaning capability. With its 2 Peak HP motor, lightweight 4.6-pound frame, and versatile blower functionality, it is an outstanding choice for car detailing and small garage cleanups. While its 1.5-gallon capacity is not meant for major renovation debris, its wall-mounted convenience and performance make it a smart investment for everyday vehicle and workshop maintenance.
