The best pressure washers for cleaning paving stones need to have high water pressure and flow to effectively remove dirt and stains. At the same time, high-quality materials and structural durability are also required to prevent problems during the use of the machine.
When choosing a pressure washer for paving stones, there are several key factors to consider, including equipment type, pressure, flow, and accessories. Here are some recommendations and considerations:
Types of pressure washers
- Electric pressure washers: Suitable for home use, usually with pressures between 1300-2000 psi, which is enough to deal with dirt on most paving stones. Lightweight and easy to operate, suitable for small-scale cleaning.
- Gasoline-powered pressure washers: Provide higher pressure (up to 3000 psi or more), suitable for more stubborn dirt and large-area cleaning. Suitable for outdoor use without power restrictions.
Key parameters
Pressure: For paving stones, it is recommended to choose equipment with a pressure of 1500-3000 psi to effectively remove moss, dirt and other attachments.
Flow rate: The higher the flow rate, the higher the cleaning efficiency. Generally, a flow rate of 1.5-2.5 GPM (gallons per minute) is ideal.
Recommended accessories
Swivel nozzles: These nozzles produce a rotating stream of water, which combines concentrated water flow with wide coverage, making them particularly useful for removing stubborn dirt.
Surface cleaners: For large flat surfaces, such as driveways or patios, they can increase efficiency and prevent splashing.
Tips
When cleaning, keep the nozzle 20 to 30 cm away from the paving surface to avoid damaging the stone.
Start with areas with less dirt and gradually move to areas with heavier dirt to better control the cleaning results.
Summary
For high-pressure cleaning of paving stones, choose an electric or gasoline-powered pressure washer equipped with a swivel nozzle or surface cleaner to effectively remove moss and dirt. Make sure to select the right pressure and flow rate for your specific needs to achieve the best cleaning results.
