Karcher T5 Surface Cleaner
Best OverallPros
- Durable metal construction
- Wide 15-inch cleaning path
- Compatible with K2 to K7 models
Cons
- Heavier than plastic models
- Not ideal for tight corners
The Karcher T5 Surface Cleaner is a favorite among homeowners for its robust metal housing and wide cleaning path. Owner reviews consistently praise its ability to clean large patios and driveways quickly, reducing cleaning time by up to 75% compared to a standard spray lance. The metal skirt protects against debris, and the integrated swivel joint prevents hose tangles.
Compatibility with Karcher K2 through K7 pressure washers makes it a versatile upgrade. Some users note that it is heavier than plastic alternatives, but the build quality justifies the weight. For large, flat surfaces, this is the most effective Karcher patio cleaner available.
Karcher T2 Surface Cleaner
Best BudgetPros
- Lightweight and easy to handle
- Affordable price point
- Good for small patios and paths
Cons
- Plastic housing less durable
- Smaller cleaning path takes longer
The Karcher T2 is the entry-level patio cleaner that delivers solid results for smaller areas. Its lightweight plastic body makes it easy to maneuver, and it is compatible with most Karcher K2 to K7 pressure washers. Owner reviews highlight its effectiveness on patios up to 200 square feet, where it removes moss and dirt without effort.
The main drawback is the plastic housing, which can crack if dropped on hard surfaces. It also covers less ground per pass than the T5, so larger jobs take longer. For occasional use on a small patio or path, the T2 offers the best value.
Karcher T7 Surface Cleaner
Best Heavy-DutyPros
- Largest cleaning width available
- Extremely durable metal build
- Handles high PSI for tough grime
Cons
- Heavy and bulky to store
- Higher price point
The Karcher T7 is the professional-grade option for large commercial patios and driveways. With an 18-inch cleaning width and a reinforced metal housing, it can handle high-pressure machines up to 3500 PSI. Owner reviews from tradespeople note that it cleans large areas in half the time of smaller models, making it a worthwhile investment for frequent use.
The weight is a factor for portability, and it requires a Karcher K4 or higher pressure washer for optimal performance. For homeowners with a very large patio or those who clean multiple properties, the T7 is the most efficient choice.
Karcher PCL 4 Patio Cleaner
Best for DeckingPros
- Adjustable cleaning angle
- Good for both patios and decking
- Lightweight design
Cons
- Not as durable as full metal models
- Smaller width than T5
The Karcher PCL 4 is designed for versatility, with an adjustable cleaning head that works on flat patios and vertical surfaces like decking. Owner reviews appreciate its ability to switch between surfaces without changing attachments. The 12-inch width is a good compromise between speed and maneuverability.
The mixed plastic and metal construction keeps weight down but is less durable than the T5 or T7. Some users report that the plastic parts can wear over time. For those who need one cleaner for patios and decking, the PCL 4 is a practical choice.
Karcher T 5 Plus Surface Cleaner
Best VersatilityPros
- Includes extra nozzles for different tasks
- Same durable build as T5
- Great for varied cleaning jobs
Cons
- Slightly more expensive than T5
- Extra nozzles may not be needed
The Karcher T 5 Plus is the same base unit as the standard T5 but comes with additional nozzles, including a dirt blaster and a turbo lance. This makes it a versatile kit for users who need to clean patios, driveways, and also tackle stubborn stains on walls or vehicles. Owner reviews like having the extra tools in one box.
The added cost is minimal for the extra accessories, making it a good value for those who want a complete cleaning set. The performance on patios is identical to the T5. If you already have a full set of nozzles, the standard T5 is a better buy.
What to check before buying a Karcher patio cleaner
Compatibility. Ensure the patio cleaner is compatible with your Karcher pressure washer model. Most cleaners work with K2 to K7, but some require a minimum PSI or flow rate. Check the product specifications before purchase.
Cleaning width. A wider cleaning path covers more ground per pass, reducing cleaning time. The T5 (15 inches) is the best balance for most users. The T7 (18 inches) is faster but heavier.
Build material. Metal housing is more durable and better for frequent use. Plastic models are lighter and cheaper but may crack over time. Choose based on how often you will use it.
Weight and storage. Heavier models like the T7 are more stable during use but harder to store. Consider where you will keep the cleaner when not in use.
Mistakes to avoid
Using on uneven surfaces. Patio cleaners work best on flat, level ground. Using them on uneven paving stones can cause the cleaner to tilt and leave streaks or miss spots.
Not using enough water flow. A patio cleaner needs a consistent water supply. Low water pressure can cause the cleaner to vibrate or not spin properly, reducing cleaning effectiveness.
Overlapping passes. Overlapping too much can create swirl marks. Move the cleaner in a steady, straight line and let the rotating jets do the work.
Ignoring the detergent function. Many Karcher cleaners have a detergent nozzle. Using a patio cleaner solution can help lift stubborn moss and algae before pressure washing.

Most Karcher patio cleaners are compatible with K2 to K7 models. Check the product listing for specific compatibility details.
Can I use a Karcher patio cleaner on decking?
Yes, but use low pressure and keep the cleaner moving to avoid damaging the wood. The PCL 4 is specifically designed for decking.
How do I stop my patio cleaner from leaving streaks?
Move the cleaner in a steady, straight line without overlapping too much. Ensure the surface is flat and the cleaner is level.
What is the difference between the T5 and T7?

Can I use a Karcher patio cleaner on block paving?

What is the warranty on Karcher patio cleaners?
Most Karcher patio cleaners come with a 2-year warranty when registered. Check the product documentation for details.
Is the T5 Plus worth the extra cost?
