When looking for the right cleaning tool for your business, it is worth understanding the differences between commercial pressure washers for industrial use and domestic ones. Domestic washers are adequate for some cleaning on the weekend, mainly car, patio, or light grime cleaning. However, these devices may lack power for demanding applications.  If your workplace needs consistent cleaning power to complete heavy-duty cleanings, you need to invest in a commercial pressure washer.

Commercial washers are great for cleaning equipment to maintain dirt workshop floors. These washers are designed for time-minimising cleaning. If you are looking for a high-pressure (such as a 3000 PSI Pressure Washer), portable petrol pressure washers, or high flow commercial pressure washer, Tools Warehouse has every possible answer to meet your cleaning challenges.

Key Features to Consider: PSI, Flow Rate & Mobility 

Understanding core specifications will help you choose the right washer for your use case.

1. PSI (Pounds per Square Inch) 

Pressure output determines how effective a washer is at cutting through grime:

• 2,500–3,000 PSI: Good for everyday commercial jobs like building exteriors or light vehicle cleaning.
• 3,000–4,000+ PSI: Essential for stripping paint, removing industrial grease, or deep cleaning concrete.

Many of our bestsellers fall into the 3000 PSI pressure washer range—an ideal balance between power and control for professional users.

2. Flow Rate (Litres Per Minute) 

A high-flow commercial pressure washer uses more water per minute, cleaning faster and more effectively, especially over large areas.

• 10–15 LPM: Sufficient for general-purpose use.
• 15–21+ LPM: Recommended for industrial or high-throughput environments.

Flow rate combined with high PSI ensures maximum cleaning performance in less time.

3. Mobility & Build 

Your workspace and mobility needs also matter:

• Portable petrol washers offer the flexibility to move across job sites.
• Skid or trailer-mounted models are perfect for fleet or contractor businesses.
• Electric units with wall mounts work well in fixed indoor setups like workshops and car wash bays.

Look for models with durable frames, large wheels, hose reels, and lift handles for easy movement and storage.
