Delicate surfaces like wood, painted surfaces, and certain types of siding may require lower pressure or specialized attachments. It's important to read the manufacturer's guidelines and adjust the pressure accordingly for different surfaces.

Yes, pressure washers come in various types to suit different applications and cleaning needs. The common types include:

• Electric Pressure Washers: These are suitable for many different sectors including domestic, commercial, and industrial. Applications include Truck Wash, Food Industry, Manufacturing, Contract Cleaning, and Farming.

Gasoline-powered pressure washers offer greater mobility and are commonly used in commercial and professional settings. Particularly useful for contract cleaners who don't always have access to mains electricity at the job site.

However, it's essential to use cleaning agents specifically recommended by the pressure washer manufacturer to avoid damage or clogging.

When used correctly, pressure washers are generally safe. However, it's important to follow safety guidelines and precautions to prevent injuries or damage.
