Great pressure washer

[This review was collected as part of a promotion.] This pressure washer works great. Very happy with the purchase. Would highly recommend. Only thing I have a complaint about is one wheel was not pinned in and kept falling off the unit. Once I turned the wheel around and installed the pin properly everything worked great. Nothing in the assembly instructions mentioned the wheel not being pinned in.

Excellent pressure washer

Have had it for a little over 5 years going on my 6th year this June 2026. Never has failed me once the gx200 motor always starts on first pull. Also I make sure to change the pump oil and engine oil periodically.

Love this pressure washer!

Easy assembly, nice fit and finish particularly the aluminum frame. Honda engine is awesome and started on the first pull. Plenty of power to pressure wash deeply for driveways, etc.

Nice Machine

[This review was collected as part of a promotion.] Machine looks very nice everything came ok. Right now it is just too cold out to use but can't wait till it warms up some. Usually Honda motors run good so we will see later. Nice and easy yo move around and since it is aluminum it is lighter and should not rust. The packaging was good too some nice heavy foam to keep it from moving.

Nice machine

So far so good. It came with an out-of-round wheel that I need to resolve with support but the unit itself is impressive.

Perfect

The honda motor and the aluminum body make this the ultimate combo! Light and easy to move, but feels sturdy and well built!

Aluminum ALH3425(-S) - Honda

Great unit. I've had good luck with Honda small engines. Brand new, but I expect the additional cost for the Honda to be with it in the future.

Hard to keep running

I have run the unit 2X. It is difficult to start and keep running. Must constantly be choked even after fully warm. Have tried several water supply options trying to eliminate variables, No water or air pocket issues. Troubleshoot advises cleaning the carburetor and jets as something may have lodged in transit. TBD,
