Pressure washer classes compared
3520, 8840, and 17600 Cleaning Units classes with example VEVOR listings and NO_MATCH ceiling.
| Class | Best for | Trade-off |
|---|---|---|
| Electric · 2000×1.76 (3520 CU) | Vehicles, furniture, and light outdoor jobs under the soft PSI cap | Not enough CU for large concrete or paint strip work |
| Gas · 3400×2.6 (8840 CU) | Decks, fences, and driveway / brick patio cleaning | Too aggressive for soft paint if forced onto job codes 1–2 |
| Gas · 4400×4.0 (17600 CU) | Heavy paint and tough concrete near the consumer ceiling | Still below commercial continuous demand — job 6 is NO_MATCH |
| Above 17600 CU | Commercial continuous / industrial wash | NO_MATCH on this site — need a commercial class |
