Karcher K7
Best OverallPros
- Highest pressure in domestic class
- Dirt blaster lance is excellent for paving
- Onboard detergent tank for moss treatment
Cons
- Heavy and bulky to move around
- Premium price point
The Karcher K7 is the flagship domestic model and is specifically designed for tough cleaning tasks like block paving. Its 180 bar pressure and 600 litres per hour flow rate provide the power needed to remove ingrained dirt and moss from paving joints quickly. The included dirt blaster lance rotates the jet for concentrated cleaning, which owner reviews consistently praise for reducing cleaning time on large driveways.
Build quality is robust with a metal pump and a large hose reel for tidy storage. The detergent system allows you to apply cleaning agents before rinsing, which is effective for biological growth on paving. Some users note the weight makes it less portable, but for dedicated block paving cleaning, the performance justifies the size.
Nilfisk C130
Best Budget for MossPros
- Excellent detergent pickup system
- Lighter and more portable than K7
- Good value for money
Cons
- Lower pressure than top competitors
- Hose can kink without reel
The Nilfisk C130 is a strong contender for block paving, especially if you need to apply moss killer and detergents frequently. Its unique detergent system draws from any container, making it easy to use specialist paving cleaners. Owner reviews highlight its reliability and the effectiveness of the included turbo nozzle for joint cleaning.
At 130 bar and 500 l/h, it is less powerful than the Karcher K7 but still sufficient for most domestic block paving. The build quality is high, with a European-made pump. It is lighter and easier to manoeuvre, making it a practical choice for smaller patios or areas with access issues.
Bosch UniversalAquatak 135
Best CompactPros
- Compact design for easy storage
- Integrated detergent tank
- Quiet operation
Cons
- Lower flow rate for large areas
- Hose length could be longer
The Bosch UniversalAquatak 135 is a well-regarded compact electric pressure washer that handles block paving effectively. Its 135 bar pressure and 440 l/h flow rate are adequate for cleaning patios and driveways, though larger areas may require more passes. The integrated detergent tank is useful for applying cleaning solutions before rinsing.
Owner reviews often mention its quiet operation compared to other models, which is a benefit in residential areas. The build quality is typical of Bosch, with a reliable pump and easy assembly. For those with limited storage space, its compact footprint is a major advantage, though the hose length may require an extension for large driveways.
Ryobi RY1419MT
Best Battery PoweredPros
- No cord or hose restrictions
- Lightweight and portable
- Part of Ryobi 40V ecosystem
Cons
- Limited run time per battery
- Less power than corded models
The Ryobi RY1419MT is a battery-powered electric pressure washer that offers freedom from power cords, making it ideal for block paving areas far from an outlet. It delivers 1900 PSI, which is sufficient for cleaning paving stones, though it lacks the sustained power of corded units. The included turbo nozzle helps concentrate the spray for joint cleaning.
Owner reviews appreciate its portability and ease of use, especially for quick clean-ups. However, the run time is limited by the battery capacity, so larger driveways may require multiple batteries. It is best suited for smaller patios or spot cleaning where cordless convenience is valued over raw power.
DeWalt DWPW2100
Best LightweightPros
- Lightweight and easy to carry
- Good pressure for the price
- Reliable DeWalt brand
Cons
- Lower flow rate for large areas
- Basic accessories included
The DeWalt DWPW2100 is a lightweight electric pressure washer that offers decent pressure for block paving at a budget-friendly price. Its 2100 PSI rating is competitive, but the 1.2 GPM flow rate is lower than the top picks, meaning it takes longer to clean large areas. The included wand and nozzle are basic but functional for general cleaning.
Owner reviews highlight its portability and ease of use, making it a good choice for smaller patios or occasional use. The build quality is solid for the price point, though it lacks the premium features like a dirt blaster lance or large detergent tank. It is best suited for light-duty block paving cleaning where budget is the primary concern.
What to Check Before Buying an Electric Pressure Washer for Block Paving
Choosing the right electric pressure washer for block paving requires understanding a few key specifications. Pressure (measured in bar or PSI) determines how forcefully water hits the surface, while flow rate (litres per hour or gallons per minute) determines how quickly you can clean an area. For block paving, a balance of both is important to shift dirt from joints without damaging the blocks.
Look for a model with a turbo or dirt blaster nozzle, which rotates the jet to concentrate cleaning power on joints and ingrained dirt. A detergent tank or pickup system is also valuable for applying moss killer or paving cleaner before rinsing. Consider the hose length and overall weight, as block paving areas often require moving around the machine.
Mistakes to Avoid When Cleaning Block Paving
A common mistake is using too high a pressure setting too close to the block paving, which can erode the jointing sand and damage the blocks. Always start with a wider spray pattern at a distance and work closer as needed. Another error is skipping the detergent application for moss and algae, as biological growth often requires chemical treatment before pressure washing.
Failing to seal the paving after cleaning is another oversight, as the joints are left vulnerable to weed growth. After cleaning, allow the area to dry completely before applying a sealant. Finally, avoid using a pressure washer on loose or poorly laid block paving, as the water pressure can displace blocks and cause uneven surfaces.
