Buying Guide
- Water temperature and pressure goals: Hot-water systems like the DigMaster are designed for oil and grease removal, with high-flow capabilities. For lighter cleaning or residential use, electric models such as the Westinghouse ePX3500 can suffice.
- Power source and mobility: Gas-powered units provide portable heat and cleaning power without electric outlets, ideal for farms and construction sites. Electric washers offer easier operation and lower maintenance for home use.
- Flow rate and pressure: High PSI and GPM translate to faster cleaning. Consider your typical job size and surface material to balance pressure with surface safety.
- Durability and maintenance: Look for triplex plunger pumps, thermal relief, and safety features (low-oil shutdown, anti-tipping design) to extend tool life and reduce downtime.
- Nozzle versatility: A five-nozzle set and quick-connect fittings improve cleaning precision for decks, siding, vehicles, and concrete. Ensure compatibility with your existing hoses and reels.
- Hose quality and length: Longer, kink-resistant hoses with steel wire braiding reduce downtime and improve reliability at higher pressures.
- Onboard accessories: Built-in soap tanks, spray guns, and compatibility with surface cleaners or foam cannons expand capabilities beyond basic washing.
- Safety and usage environment: Gas-powered units require proper ventilation and safe fuel handling, while electric models are generally safer for indoor or enclosed spaces.
