About Pressure Washers for Patios
For typical block paving and Indian sandstone, aim for 130–160 bar at 7+ L/min, paired with a surface-cleaner attachment (a covered rotating-nozzle disc). This combination cleans 5–10× faster than a fan lance alone and leaves no streaks.
Top patio picks: Kärcher K5 Premium Smart Control (with T7 patio cleaner), Nilfisk Core 140 Pro Patio Bundle and Bosch AdvancedAquatak 160 with surface cleaner. Petrol models suit anything over 100 m² of slabs.
Avoid using turbo nozzles on softer stones like sandstone, limestone and old York paving — they'll pit the surface. Stick to a fan lance or surface cleaner.
