Customer Reviews
With 800 PSI and 1.5 GPM, this thing packs a serious punch, delivering way more force than your childhood water blaster ever dreamed of. It doesn’t just spray—it attacks dirt, mud, and stubborn gunk with a vengeance. The 6-in-1 nozzle adds versatility, letting you adjust from gentle spray to full-blown pressure surge, kind of like switching from casual mist to "absolutely wreck everything in its path" mode. It’s not quite a full-sized pressure washer, but for quick cleanups, car washes, and patio maintenance, it’s perfect.
Worked great right out of the box! Tested it on my patio and it’s a remarkable difference!
This cordless pressure washer exceeded my expectations right out of the box. First of all, the battery arrived fully charged, which was a nice surprise and meant I could jump right into using it. Assembly was super easy; I didn’t even need the instructions, though I did glance at them to figure out what a couple of the optional add-ons were for. Everything clicked into place smoothly. Highly recommend for anyone who wants an easy-to-use pressure washer without the hassle of gas or cords! I know I'll be hesitant to use it on the full blast stream setting at first. I don't want to remove my car's paint! That is probably a better setting for the tires. lol Overall, it's very easy for anyone to use, even if you've never handled a pressure washer before (like me). I'm very pleased.
This comes in a case and really has everything needed. I charged it up and spread the lawn with fertilizer. The 40-degree spray sent the liquid about eight feet. Good enough for me, but I'm not washing cars all day with it, either.
The Andeman Cordless Pressure Washer with a 3.0Ah battery, 800 PSI, and 1.5 GPM flow rate is designed for portability and versatility, making it a practical choice for cleaning cars, patios, fences, and more. The 6-in-1 nozzle offers flexibility for different spray patterns without the hassle of changing attachments, and the included foam bottle is a bonus for car washing. Assembly is straightforward, and the unit is lightweight and compact for easy storage. However, it may not be ideal for heavy-duty cleaning tasks like stripping paint or deep-cleaning concrete. The pressure is best for maintenance rather than deep grime removal. All in all, excellent value for the money.
