Great Purchase

I just purchased the Westinghouse Power pressure washer and I used it for the first time this weekend to wash the car and it worked better than I expected. I loved the soap dispenser it made washing the car so easy.

Verified Purchase

Power Washer Great-be careful of Allstate Warranty

If you add the Allstate 4 year warranty, be careful.... Allstate counts the manufactures warranty (1 year) as part of the 4 years... Kind of shady on their part. I ended up canceling the warranty.

Great product

I bought this back in January but I had not had a chance to use it until just recently. Easy assembly and easy to use, excellent performance, great water pressure, light weight and very good gas consumption. One full tank went through the whole driveway and a pretty good size back porch. I'm satisfied with this purchase and I'd buy it again.

So far so good!

It has worked great! Also purchased the16.5” Westinghouse Surface Cleaner for my patio and it works fabulous with the pressure washer…very easy to use as a combo. I would recommend not setting the pressure washer on your concrete surface when running because the vibration of it while in use will create indentation marks where the pads set due to the vibration.

Works Well

Worked like a champ out of the box. Clear directions for assembly. Started up with two pulls. Cleaned 2 years worth of siding mold/mildew easily without any soap. Easy to move around. Connections were solid, no leaks. Only flaw in the design, add a twist tie/ zip tie to the gun water supply tube and detergent tube connector to prevent touching the engine and melting.

Good value for the money

Very good pressure washer, it would have been nice if they had properly secured the soap dispenser line so it didn't rub up to the exhaust and burn it. And the oil was not drained for shipping like it said it was so had to adjust it manually after adding the recommended amount of oil. The pressure washer itself is good though.

Will have to determine reliability with time.

I followed the manual setup instructions carefully, but the WPX3400 pressure washer did not start easily. When I moved the choke from on to run, it started up.

Quality pressure washer for the price

Pressure washer construction is solid and performing well. It gets easier to use/handle after first few minutes of use. Glad I bought this model with high pressure power because I have 2-storey house to clean and getting close to the top and cleaning is not easy. Enjoyed cleaning my driveway and sidewalks - was a breeze and concrete slabs are looking clean. Wish it came with 50-foot-long pressure hose. Overall, pretty good quality pressure washer for the price.

Poor craftsmanship

I used my new pressure washer for about 30 minutes. Was really happy with it until I noticed it was falling apart. A bolt mounting the pump to the motor had fallen off. The next thing I knew, 2 of the flange nuts holding the motor to the frame fell off, If i knew I was going to have to rebuild the machine, I would have bought something else. I'm guessing this will be a systemic issue. I did go back and retighten every bolt on the machine.

Nightmare

Just took it out of the box and put it together. I followed the instructions to the letter. This is the most difficult power washer I have ever had to start!! I've only gotten it started twice, And had to stop it To take a couple of breaks. I'm on my third start and I'm dying trying to start this thing . I sure wish I hadn't bought this
