Flow rate

10 days ago
I just purchased this to potentially start a pressure washing business because it had a good pump and a 4 gallon per minute flow rate. So far it's working excellent.

The ultimate machine

12 days ago
The PowerShot PS60843 49-State is an absolute beast of a machine. From the first use, you can tell it’s built for serious work. The pressure is strong and consistent, making it easy to clean driveways, sidewalks, siding, and heavy grime without struggling. It starts up reliably and runs smooth, even during longer jobs. The build quality feels solid and durable, and the mobility makes it easy to move around job sites. It definitely saves time and delivers professional-level results. If you’re serious about pressure washing—whether for business or home use—this machine is worth every dollar.
