Best Foam Cannon for Caravans

The Karcher Foam Nozzle is specifically designed for the K Series pressure washers, which are among the most popular for caravan owners. It produces a thick, clingy foam that adheres to vertical caravan sides without running off, allowing the cleaning solution to dwell and break down dirt effectively. Owner reviews consistently praise its build quality and the consistency of the foam it produces.

Its adjustable nozzle lets you switch from a wide fan for large panels to a more focused stream for wheels and arches. While the 0.5L capacity is smaller than some universal models, it is sufficient for a single caravan wash without needing a refill. The brass connector ensures a leak-free seal, a common complaint with cheaper plastic alternatives.

The Nilfisk C110.5-X is a universal foam cannon that works with most pressure washers using an M22 connection, making it a great option for those who do not own a Karcher. Its 1L capacity means you can mix a strong solution and cover a large caravan without stopping to refill, saving time during the wash process.

Owner feedback indicates that while the foam is not as thick as the Karcher nozzle, it is more than adequate for pre-washing and removing light grime from caravan bodies. The adjustable dial allows you to control the dilution ratio. The main trade-off is the plastic construction, which some users report can be less durable than brass alternatives over several seasons of use.

The Bosch Universal Plus Foam Nozzle is designed specifically for Bosch pressure washers, ensuring a secure and leak-free connection. It produces a consistent foam that is ideal for applying snow foam or caravan-specific cleaning solutions. The nozzle is easy to adjust, allowing you to control the spray pattern for different areas of the caravan.

Reviews from Bosch owners highlight its reliability and the quality of the foam it produces, which clings well to vertical surfaces. The 0.5L capacity is standard for this class of accessory, but it may require a refill for larger caravans. Its build quality is solid, with a robust plastic housing that withstands regular use.

The Karcher T5 T-Racer is a surface cleaner that also features a foam dispensing function, making it a versatile tool for large caravan owners. It uses rotating jets to clean flat surfaces and applies foam simultaneously, which can significantly speed up the cleaning process for the large side panels of a caravan. It is particularly useful for removing stubborn road film.

While it is not a dedicated foam cannon, it provides a good layer of foam that helps to loosen dirt before the rotating jets rinse it away. Owner reviews note that it is excellent for the roof and sides of caravans but less effective for detailed areas. The integrated foam tank holds 0.6L, which is adequate for a single pass on a medium-sized caravan.

The VonLux 1L Universal Foam Cannon is an entry-level option that offers great value for money. It comes with multiple adapters to fit most pressure washers and features a 1L tank, which is ideal for covering a caravan without refills. It includes a brass connector, which adds durability compared to all-plastic budget models.

Owner reviews are mixed on foam thickness, with some users achieving great results by adjusting the dilution dial, while others find it less consistent than premium brands. It is a solid choice for occasional caravan cleaning where budget is the primary concern. The build quality is acceptable for the price, though some users report leaks from the bottle seal over time.
