I recently purchased this and used for an hour right after assembly. I am impressed with the power of the water stream and the fact that several nozzle spray patterns are provided. For the price, I doubt you can find a more powerful pressure washer. This washer will easily handle any cleaning job around the house or workshop.

Bought this to replace a very old power washer and was not disappointed. Easy assembly, informative but not complicated user guide as far as details on proper care and products to use. Used it a handful of times without fail, super happy with it. Then it started to sound like the engine started choking and kept stopping. Start up, then stopped. Appeared gas was emptying out of the black plastic manifold under the carburetor. Not sure what the issue is.

I bought this so I could get the drive and walkway of our home cleaned up as well as the house when we paint. We live in Florida any anyone here will tell you concrete takes a beating during the rainy season. Needed something to get ride of the green slimy stuff and dirt. This pressure washer did it. Paired with the Westinghouse 16.5 Surface cleaner the job was done before noon. Worked great, cleaned vertically well, was easy to use and start up was a breeze. One hiccup, watch where your hose is sitting, tire vibration will eventually cut a rubber hose.

Wanted to get a powerful gas pressure washer. This Westinghouse 3400 comes highly recommended. Assembly was very easy. Just carefully followed instructions and did a quick job to get acclimated. All went well. Look forward to tending to my cement driveway and walkways soon. Happy with my purchase.

The unit does what its supposed to do. Easy to set up, and use. Cleaned my lanai area and a PVC fence behind my yard over the course of a couple hours. Plenty of power. The only thing keeping this from 5 stars is that it is a challenge to start. Even after the engine is warm. Once started, no issues.

Assembly was easy and machine cranked right up. Worked great to wash my truck. Looking forward to using the driveway cleaning attachment. Only issue so far is the red and white nozzle degree markings are different on the machine and the paper manual. I think what is on the machine is correct.

I have used it three times so far in two months. Great design and features, but concerned with starting issues. I will be contacting support to see what the issue can be. I used fresh gas and it is brand new. I would expect it to start on two pulls, three max.

The WPX3400 gas version is a compelling option if you: Have relatively heavy cleanup jobs (driveways, decks, siding) where high PSI is beneficial. Don't mind the maintenance and care that a gas unit requires (fuel, oil, winterization). Want strong performance at a more affordable price than premium brands. However, if you'll only occasionally use it or have mostly lighter tasks, a high-end electric or smaller gas unit might suffice with greater convenience and lower maintenance.

Purchased the WPX3400 to replace a previous Westinghouse pressure washer that has served me well but finally failed. Was happy with the performance, so I stuck with the brand. Note: registration card asks for a serial number, but the label on the new unit is not the same as the one pictured on the registration instructions. I could not find a serial number anywhere on the washer and I looked thoroughly.

Ran it for about five hours the first day I used it for cleaning steps, porches, painted fences, and concrete surfaces and it performed wonderfully. It worked well with the Westinghouse 16.5" stainless steel surface cleaner to clean a concrete driveway, three-car concrete parking pad, and two walkways it much less time than using a nozzle. I also like the relatively small footprint compared to other brands with similar PSI making it easier to store.
