There are some considerations to keep in mind. While the foam cannon is effective for creating thick foam, its performance may vary depending on the cleaning concentrate used. Lower-quality soaps can affect the thickness and effectiveness of the foam produced. While the build quality appears solid, it's essential to handle it with care to ensure longevity.
