Capacity, Power, and Build Specs
Tank Capacity
Edge: Shop-Vac 12 Gal Pump Wet Dry Vac
The Shop-Vac 5871205 offers a 12-gallon tank, while the Shop-Vac 8 Gallon Stainless Steel model provides 8 gallons. The larger tank on the 5871205 allows you to collect more debris and liquid before needing to empty it. This makes it better for larger jobsites or workshops where you generate significant waste. The 8-gallon unit is more compact but requires more frequent emptying during heavy use. If you need to handle larger volumes of water or dry debris without interruption, the 12-gallon capacity is the practical choice for sustained work.
Motor Power
Edge: Shop-Vac 8 Gallon Stainless Steel Wet/Dry Vac
The Shop-Vac 8 Gallon Stainless Steel Wet/Dry Vac features a 6.0 Peak HP motor, whereas the 5871205 uses a 5.0 Peak HP motor. Higher peak horsepower generally indicates stronger suction power for picking up heavy debris. The 6.0 HP motor in the stainless steel model gives it an advantage in raw power for demanding tasks. The 5.0 HP motor in the 12-gallon unit is still capable for standard wet and dry cleaning, but the 8-gallon model has the edge in stated motor performance. You should consider this if suction strength is your primary concern.
Tank Material
Edge: Shop-Vac 8 Gallon Stainless Steel Wet/Dry Vac
The Shop-Vac 8 Gallon Stainless Steel model is built with a heavy-duty stainless steel tank. The 5871205 model uses a black tank, which is typically plastic in this product line. Stainless steel is more resistant to corrosion, dents, and punctures compared to standard plastic tanks. This makes the 8-gallon unit more durable for harsh job site environments or prolonged exposure to moisture. If you work in wet conditions or rough areas, the stainless steel construction offers better longevity and protection for the vacuum body.
Hose Length
Edge: Shop-Vac 12 Gal Pump Wet Dry Vac
The Shop-Vac 5871205 comes with an 8-foot hose, while the Shop-Vac 8 Gallon Stainless Steel model includes a 7-foot hose. The longer hose on the 5871205 provides a slightly greater reach without moving the vacuum itself. This can be helpful when cleaning large floors or hard-to-reach corners in a workshop or garage. The difference is small, but the extra foot of hose on the 12-gallon model offers a minor convenience advantage for extended cleaning ranges. Both lengths are sufficient for most standard household and job site tasks.
Airflow Performance
Edge: Shop-Vac 8 Gallon Stainless Steel Wet/Dry Vac
The Shop-Vac 8 Gallon Stainless Steel model delivers 145 CFM of airflow. The airflow specification for the 5871205 is not listed in the provided data. Higher CFM generally means faster debris removal and better ability to lift heavier materials. The 145 CFM rating on the 8-gallon model indicates strong air movement for its size. Without the specific CFM value for the 5871205, we cannot directly compare their airflow efficiency. You should rely on the stated 145 CFM for the 8-gallon unit as a measure of its air performance.
