Versatile Foam Attachment for Cars: Tested Impact on Detailing Speed

Among the arsenal of tools streamlining modern detailing, the foam cannon attachment stands out for its efficiency. But versatility becomes its true strength—and the rapid iterations of off-the-shelf products highlight this potential. Testing the impact of specific models directly on speed, we encountered three notable contenders.

There was the specialist Pressure Washer Tee, a designated splitter allowing two nozzles to run simultaneously off a single wand. Complementing this were the Dual Pressure Washer Nozzle with its 4PCS Spray Nozzles—easily clipped into the Tee—offering rapid switching yet requiring manual adaptation for pure foam duty. Then, the Foam Cannon Dual-Connector Accessory presented a more integrated solution, feeding foam from a dedicated line (requires a splitter at the source). This unit’s built-in sprayer array added an immediate layer of diversification without the need for multiple tips attached to its dual-deck connection.

Ultimately, the results showed that the integrated cannon-based system provided the quickest transition to and from high-pressure cleaning, though the Tee setup offered unique redundancy in power wash/free rinse scenarios, proving that speed hinges as much on workflow planning as the tool itself.
