Buying Guide: Power and Cleaning—What to Consider
- Power needs: Determine the max PSI and GPM you require for your cleaning tasks. Higher PSI helps with stubborn dirt but may be unnecessary for light maintenance.
- Portability: If you need a unit for on-the-go use, consider weight, handle design, and wheels. Inverters and compact models are easier to move and store.
- Outlets and fuel: For generators, confirm outlet types (120V, RV, DC) and run-time per tank. For electric washers, ensure compatibility with your power source and any extension requirements.
- Detergent compatibility: Onboard soap tanks or foam cannons simplify applying detergents to many surfaces.
- Maintenance: Look for simple assembly, easy storage, and durable components (wand, hose, nozzle set) to lengthen the life of your equipment.
- Use-case scenarios: RV camping, emergency home backup, deck cleaning, driveway sanitation—match the product’s power, weight, and water delivery to the task.
