An adjustable fan is what separates a general foam cannon from a professional tool. Open the pattern wide to coat a roof and side panels in a few sweeps, or narrow it to concentrate foam on wheels, grilles and the lower rockers where dirt builds up most, so less product is wasted.
- Combine fan adjustment with the soap mix to suit light dust in summer or heavy grime in winter
- Use a wide pattern for pre-wash on large SUVs and vans
- A narrow pattern makes it easier to foam wheel faces and engine bays precisely
- Flush the cannon after each session so dried soap does not restrict the fan
