Armor All AA255: problems, parts and running costs
Checked: 2026-10-09
Summary
The AA255 is a compact 2.5-gallon wet/dry utility vac that goes wrong mostly through filter misuse: fine dust such as drywall dust or fireplace ash passes the standard filter and can damage the motor. Running costs are limited to replacement filters, and the research located no prices or replacement intervals for them. It is a good buy at $55 or less from stores like McCoy’s; above $75 the small tank is hard to justify.
Common problems and fixes
- Fine dust getting into the motor — the operator manual warns against vacuuming drywall dust or fireplace soot and ash with the standard filter, because those fine particles may not be captured and can damage the motor [1]. For that kind of cleanup, the fine dust cartridge V2CFF is the safer fit where Cleva still sells it [3]. Warranty: 2-year limited under household use, 90-day limited for commercial, industrial or rental use; the warranty covers defects in workmanship and materials, and the manual’s dust warning implies dust damage is not a defect claim [1][3].
- Filter mix-ups between wet and dry jobs — the foam sleeve filter must be removed after liquid pickup and the reusable cloth filter installed before dry pickup; forgetting the swap is the most common maintenance mistake [1].
- Blower not blowing — the blower works only with the hose inserted into the separate blowing port, not the standard intake [1][3].
- Vacuum will not operate — the manual’s troubleshooting lists no power supply or a faulty power cord as the primary causes to check [1].
- Stock and parts risk — the vac no longer appears on Armor All’s own website and Cleva’s direct store lists it sold out, so it may be legacy or discontinued [2][3].

When it is a good buy
- At $55 or less it is a strong value for a compact wet/dry vac with blower function and car-detailing nozzles; McCoy’s Building Supply lists it at $52.99 (October 2026) [3][5].
- At $56-70 it is still reasonable for the feature set, though competing 2.5-gallon shop vacs from Craftsman and Shop-Vac are available at similar prices [5].
- Above $75 it is weak value — Cleva’s direct store lists it at $75.99 marked sold out, and larger-capacity alternatives exist at that money [3].
- The black AA255W variant sells at Walmart for $67.99-$69.99; it is the same body in a different color, not a different capacity [4].
- Alternatives: a Craftsman or Shop-Vac larger-capacity shop vac is the better choice when the 2.5-gallon tank is too small for your jobs [5].
