Karcher T5 Surface Cleaner
Best OverallPros
- Compact size reaches tight caravan corners
- Low-pressure design protects paint and decals
- Anti-splash guard reduces mess
Cons
- Only compatible with Karcher pressure washers
- Smaller diameter means slower coverage
The Karcher T5 is purpose-built for lighter cleaning tasks, making it ideal for caravan exteriors. Its 12-inch diameter allows you to manoeuvre around windows, vents, and awning rails without overspray. Owner reviews on Amazon consistently praise its ability to remove algae and road grime without etching caravan graphics.
The integrated dirt blaster technology channels water into a focused jet, while the low profile prevents water from splashing up onto already-cleaned areas. It connects directly to Karcher's K2 to K7 range via a quick-release coupling, though you will need an adapter for older models.
VonHaus Universal Patio Cleaner Attachment
Best BudgetPros
- Works with most pressure washer brands
- Soft bristle edge prevents scratching
- Very affordable price point
Cons
- Plastic housing feels less durable
- Some users report leaking after heavy use
The VonHaus universal attachment is an excellent entry-level option for caravan owners who do not want to commit to a brand-specific tool. It includes three adapters to fit Karcher, Bosch, Nilfisk, and most other pressure washers. The 14-inch head provides a good balance of coverage and control on caravan sides.
Owner feedback on Amazon highlights its effectiveness on light moss and dirt, though it struggles with stubborn grime compared to higher-end models. The soft bristle ring is a thoughtful addition for protecting caravan decals and paintwork. For occasional use, this is a solid choice.
Bosch F016800498 Patio Cleaner
Best DurabilityPros
- Steel housing withstands drops and bumps
- Large coverage reduces cleaning time
- Easy to disassemble for cleaning
Cons
- Heavier than most competitors
- Only fits Bosch pressure washers natively
The Bosch F016800498 is built like a tank, with a full steel shroud that protects the internal mechanism from knocks. This makes it a great choice for caravan owners who store their gear in tight lockers. The 15-inch head covers ground quickly, so you can clean a full caravan side in fewer passes.
Amazon reviews note that it maintains consistent pressure even on higher PSI settings, and the rotating nozzles do not clog easily. The main trade-off is weight: at 2.4 kg, it is noticeably heavier than the Karcher T5. It also requires a Bosch pressure washer for a direct fit, though adapters are available.
Nilfisk 128472857 Patio Cleaner
Best for Large AreasPros
- Largest head for fast cleaning
- Rotatable handle for awkward angles
- Good water flow management
Cons
- Heavy and bulky for storage
- Plastic components can crack if dropped
The Nilfisk 128472857 is designed for covering large flat surfaces quickly, making it suitable for caravan awnings and large side panels. The 16-inch rotating head and ergonomic handle allow you to clean with less fatigue, though the weight is a factor when working overhead on a caravan roof.
Owner reviews on Amazon and retailer sites mention that it works exceptionally well on Nilfisk pressure washers, delivering streak-free results on painted surfaces. The main drawback is its size: it can be cumbersome to store in a caravan locker, and the plastic housing has been reported to crack if subjected to rough handling.
Ryobi RYAC802 Patio Cleaner
Best VersatilityPros
- Dual nozzle system for different surfaces
- Includes universal adapter kit
- Lightweight and easy to handle
Cons
- Plastic bristles can wear quickly
- Not as effective on heavy moss
The Ryobi RYAC802 offers versatility with its dual nozzle system, allowing you to switch between a wide fan for general cleaning and a concentrated jet for stubborn spots. It comes with a universal adapter that fits most major pressure washer brands, including Karcher, Bosch, and Nilfisk. The 14-inch head is a good middle ground for caravan use.
Amazon and retailer reviews indicate it is a reliable performer for regular caravan washing, particularly on painted surfaces and awnings. However, the plastic bristle ring is less durable than the rubber skirts found on premium models, and some users report it wearing out after a season of heavy use.
What to Check Before Buying a Patio Cleaner for Your Caravan
Choosing the right patio cleaner for your caravan involves more than just picking the cheapest option. Consider these factors to avoid damaging your vehicle's finish.
Pressure compatibility: Caravan paint and decals are more delicate than concrete or block paving. Look for a cleaner rated for 1000-2000 PSI. Higher pressures can strip paint or etch graphics.
Diameter and manoeuvrability: A 12-14 inch head is ideal for caravans. Larger heads cover more area but are harder to control around windows, vents, and awnings. Smaller heads offer better precision.
Connection type: Check whether the cleaner uses a proprietary fitting (like Karcher's quick-connect) or a universal M22 thread. Universal models offer more flexibility if you own multiple pressure washers.
Material and build quality: Steel housings are more durable but heavier. Plastic models are lighter but may crack if stored roughly. Consider how you will store the cleaner in your caravan.
Mistakes to Avoid When Using a Patio Cleaner on a Caravan
Even the best patio cleaner can cause damage if used incorrectly. Here are common pitfalls to avoid.
Using too high a pressure: Many caravan owners assume higher PSI means faster cleaning. In reality, pressures above 2000 PSI can damage seals, decals, and paint. Stick to the manufacturer's recommended range.
Neglecting the skirt condition: The rubber or bristle skirt on a patio cleaner prevents water spray and protects the surface. A worn skirt can cause scratches. Replace it as soon as you notice wear.
Cleaning in direct sunlight: Hot surfaces cause cleaning solutions to dry too quickly, leaving streaks. Wash your caravan in the shade or during cooler parts of the day for best results.
Forgetting to rinse the cleaner: After each use, flush the patio cleaner with clean water to remove grit and debris. This prevents internal damage and extends the tool's life.
FAQs
Can I use a patio cleaner on my caravan's roof?
Yes, but use a lightweight model like the Karcher T5 to reduce fatigue and avoid damaging roof seals.
Will a patio cleaner damage my caravan's decals?
Not if you keep the pressure below 1800 PSI and maintain a safe distance. Always test on an inconspicuous area first.
Do I need a special pressure washer for a caravan patio cleaner?
No, most patio cleaners attach to standard pressure washers. Check the connection type and use adapters if needed.
How often should I clean my caravan with a patio cleaner?
Every 3-4 months is sufficient for most climates. More frequent cleaning may be needed if you park under trees or near the coast.
Can I use a patio cleaner on my caravan's awning?
Yes, but use a low-pressure setting and avoid direct contact with the fabric. A soft bristle attachment is safer.

A 12-14 inch diameter offers the best balance of coverage and control for caravan walls and awnings.
Is a universal patio cleaner as good as a brand-specific one?

How do I clean the patio cleaner after use?
Flush it with clean water by running the pressure washer for 30 seconds without the trigger locked. Dry it before storage.
