Karcher 15m Extension Hose (Original Accessory)
Best OverallPros
- Kink-resistant reinforced design works well around caravan corners
- Quick-connect fittings attach securely to all Karcher models
- Lightweight at 1.2kg, easy to carry in a storage locker
Cons
- Only compatible with Karcher pressure washers without an adapter
- PVC material can feel stiff in cold weather
The Karcher 15m Extension Hose is the most popular choice among caravan owners because it provides the ideal reach for cleaning both sides of a 6-8m tourer without moving the pressure washer. Owner reviews on Amazon and caravan forums consistently praise its ability to resist kinking when dragged around the vehicle, a common frustration with cheaper hoses.
This original Karcher accessory is rated for up to 200 bar, which covers the output of all K2 to K7 models. The reinforced PVC construction holds up well against gravel and grass, though some users note the hose becomes less flexible in temperatures below 5 degrees Celsius. For most touring conditions, this is the most reliable option available.
DeWalt 15m Rubber Pressure Washer Hose
Best Budget / DurabilityPros
- Rubber construction stays flexible in cold weather
- Universal 3/8" BSP fittings work with most non-Karcher machines
- Rated for higher pressure than most caravan washers need
Cons
- Heavier than PVC hoses at 2.4kg
- Requires separate adapters for Karcher quick-connect systems
The DeWalt 15m Rubber Hose is the top choice for caravan owners who use a non-Karcher pressure washer or want a hose that remains pliable in winter conditions. Rubber construction resists abrasion from gravel driveways better than PVC, and the 300 bar rating means it will never be the weak link in your system.
Aggregated owner reviews highlight the hose's ability to lie flat without coiling memory, making it easier to pack away after use. The main trade-off is weight: at nearly double the weight of the Karcher hose, it is less convenient to carry around a campsite. For budget-conscious buyers who prioritise long-term durability, this is the best value hose available.
Nilfisk 15m High Pressure Hose (Original Accessory)
Best for Nilfisk UsersPros
- Genuine Nilfisk accessory with guaranteed fit and seal
- Lightweight and easy to handle around the caravan
- Kink-resistant braiding prevents flow interruptions
Cons
- 150 bar max may limit use with higher-pressure models
- Nilfisk-specific fittings require adapters for other brands
The Nilfisk 15m High Pressure Hose is the direct replacement for owners of Nilfisk C110, C120, and C135 pressure washers. It offers the same kink-resistant performance as the Karcher hose but is tailored to the Nilfisk quick-connect system, which uses a different locking mechanism.
Owner feedback on caravan forums rates this hose highly for its lightweight feel and reliable sealing. The 150 bar rating is adequate for cleaning caravans, as most users run their machines at lower pressures to avoid damaging seals. The main limitation is the proprietary fittings, which make it difficult to use with other pressure washer brands without purchasing additional adapters.
Bosch 10m Extension Hose (Original Accessory)
Best Compact StoragePros
- Compact 10m length coils into a small storage bag
- Genuine Bosch accessory with reliable quick-connect
- Lightest option at 0.9kg
Cons
- 10m may require repositioning the washer for large caravans
- Only compatible with Bosch pressure washers
The Bosch 10m Extension Hose is the best choice for caravan owners with limited storage space. At just 0.9kg, it takes up minimal room in a locker or under a seat, and the 10m length is adequate for cleaning a compact caravan or campervan without excessive slack.
Owner reviews note that the hose is less prone to kinking than generic alternatives, though the shorter length means you will need to move the pressure washer to reach the far side of a twin-axle caravan. For owners of Bosch EasyAquatak or UniversalAquatak machines, this is the most convenient extension hose available.
Karcher 20m Heavy Duty Hose (Original Accessory)
Best for Large MotorhomesPros
- 20m length allows cleaning around 8-10m motorhomes without moving the washer
- Heavy-duty construction resists punctures from gravel
- Karcher quick-connect ensures leak-free operation
Cons
- Heavier and bulkier to store than 15m options
- More expensive than shorter alternatives
The Karcher 20m Heavy Duty Hose is designed for owners of large motorhomes or twin-axle caravans who need maximum reach. The extra 5m over the standard 15m hose allows you to clean the entire vehicle without moving the pressure washer, which is especially useful on campsites with limited space.
Owner reviews on caravan forums describe this hose as exceptionally durable, with the reinforced PVC standing up to repeated dragging across gravel and tarmac. The main downside is the bulk: at 1.8kg, it takes up more storage space and is heavier to carry. For owners of large vehicles who prioritise convenience over portability, this is the best hose available.
What to Check Before Buying a Pressure Washer Hose for Your Caravan
Choosing the right hose for caravan cleaning involves more than just picking the longest option. The most important factor is compatibility with your pressure washer's connection system. Karcher uses a proprietary quick-connect system, while Bosch, Nilfisk, and DeWalt each have their own fittings. Universal hoses with 3/8" BSP threads offer the widest compatibility but may require adapters.
Length is the second critical consideration. A 15m hose is the sweet spot for most single-axle caravans, allowing you to clean both sides without moving the washer. For motorhomes over 7m, a 20m hose saves time and effort. Shorter 10m hoses are fine for small campervans but will require repositioning for larger vehicles.
Material choice affects flexibility and durability. Rubber hoses remain flexible in cold weather and resist abrasion better than PVC, but they are heavier. Reinforced PVC hoses are lighter and more affordable but can become stiff in winter and are more prone to kinking if stored incorrectly.
Mistakes to Avoid When Buying a Caravan Pressure Washer Hose
One common mistake is buying a hose that is too long. A 25m or 30m hose may seem convenient, but the extra weight and bulk make it difficult to store and handle, and the pressure drop over such a long hose can reduce cleaning performance. Stick to 15m for most caravans and 20m for large motorhomes.
Another mistake is ignoring the pressure rating. Caravan pressure washers typically operate at 100-150 bar, but using a hose rated for only 100 bar with a 150 bar machine risks bursting. Always choose a hose with a maximum pressure rating that exceeds your pressure washer's output by at least 20%.
Finally, avoid buying cheap universal hoses that come with multiple adapters. Owner reviews frequently report leaks at the adapter connections, which can waste water and reduce pressure. A genuine brand accessory or a high-quality universal hose with proper fittings is a better investment.
FAQs
What length of pressure washer hose do I need for a caravan?
A 15m hose is ideal for most single-axle caravans, while a 20m hose is better for motorhomes over 7m in length.
Can I use a standard garden hose with a pressure washer?
No, standard garden hoses are not rated for high pressure and will burst. Always use a dedicated high-pressure washer hose.
Are Karcher hoses compatible with other pressure washer brands?
Karcher uses a proprietary quick-connect system, so you will need an adapter to use their hoses with other brands.
What is the best material for a caravan pressure washer hose?
Reinforced PVC is lightweight and affordable, while rubber is more durable and flexible in cold weather but heavier.
How do I stop my pressure washer hose from kinking?
Choose a hose with braided reinforcement and store it on a reel or in loose coils to prevent memory kinks.
Can I connect two hoses together for extra length?
Yes, but each connection point is a potential leak source, and longer hoses reduce pressure at the nozzle.
What pressure rating do I need for a caravan hose?
Look for a hose rated at least 150 bar, which covers the output of most domestic pressure washers used for caravans.
Do I need a hose reel for my caravan pressure washer hose?
A hose reel helps prevent kinking and makes storage easier, but it is not essential if you have space to coil the hose loosely.
Are universal hoses as good as brand-specific ones?
Universal hoses with 3/8" BSP fittings can be excellent, but you may need adapters that can introduce leaks.
How do I maintain my pressure washer hose?
Rinse the hose with clean water after each use, drain it completely, and store it away from direct sunlight to prevent UV damage.
