Its triplex plunger pump is designed for reliability under demanding workloads, making it suitable for medium to heavy-duty outdoor cleaning, including decks, driveways, and industrial surfaces. The included five quick-connect tips expand cleaning options beyond the standard spray settings, including a chemical nozzle for tough stains.
Canpump Gas Pressure Washer: 3600 psi / 5 GPM
Designed for professional concrete and fleet cleaning, this Canpump model delivers 3600 psi at 5.0 GPM and uses a Loncin G390F engine for robust performance. The CE 3650 S triplex pump provides durability with a forged brass manifold and ceramic-coated plungers, while the external unloader facilitates easier maintenance. This combination is well-suited for large outdoor areas and demanding cleaning tasks across commercial applications.
WOJET 20″ Pressure Washer Surface Cleaner
WOJET’s 20-inch surface cleaner attachment is designed to deliver stripe-free cleaning over large flat surfaces like driveways, sidewalks, decks, and patios. With four wheels and dual handles, it offers improved mobility and control, reducing operator fatigue. The stainless steel construction and sealed swivel minimize maintenance needs while maintaining durability under high-pressure operation. It’s a practical upgrade for expanding a belt-driven setup to surface-wide cleaning tasks.
Simpson Cleaning 4400 PSI Gas Pressure Washer
The Simpson 4400 PSI power washer combines a CRX engine with a AAA industrial triplex pump, delivering 4400 PSI at 4.0 GPM for professional-grade cleaning. It includes a 50-foot high-pressure hose and a comprehensive nozzle tip assortment for versatile tasks, from decks and siding to concrete surfaces. The design emphasizes reliability and ease of use for contractors and maintenance crews handling frequent cleaning jobs.
Canpump Belt Drive High Flow 3600 PSI / 5 GPM
This belt-driven Canpump model provides 3600 psi at 5 GPM with a 13 HP Loncin engine and electric start for convenient ignition. The belt-drive design reduces wear, helping extend pump life, and the external unloader adds straightforward maintenance access. It’s positioned for heavy-duty commercial use, offering a balance of flow, power, and reliability for frequent cleaning cycles in industrial settings.
Buying Guide: Key Purchase Considerations
When selecting a belt-driven pressure washer, consider these factors to ensure the best fit for your needs:
- Power and flow: Higher PSI and GPM configurations accelerate cleaning on tough surfaces but require appropriate nozzles and safety practices. For large areas, aim for 3600–4400 PSI with 4–5 GPM.
- Pump type and drive: Triplex pumps are durable and repairable; belt-driven drives reduce engine wear and can slow pump RPM for longer life, though they may trade some startup responsiveness.
- Engine and fuel: Gas engines (e.g., Loncin, CH series) provide mobility and power; consider fuel availability, starting reliability, and maintenance requirements for frequent use.
- Hose and reach: A long non-marking hose minimizes surface damage and streaking. Look for 50-foot or longer hoses with quick-connect fittings for ease of use.
- Accessories: Quick-connect nozzles expand versatility (0°, 15°, 25°, 40°, chemical or soap). Surface cleaners improve efficiency on large flat surfaces and reduce operator fatigue.
- Maintenance and serviceability: External unloaders, accessible pump components, and straightforward maintenance features reduce downtime and long-term costs.
- Portability and setup: Weight, wheel configurations, and handle design influence transport across work sites. Electric start can simplify ignition, especially in cold conditions.
- Surface care: For property owners, non-marking hoses and surface-cleaner attachments help protect concrete, wood, and siding while delivering professional results.
