  • Westinghouse Undercarriage Washer
Undercarriage Washer worked great, even with an Electric Pressure Washer. Pressure was great, and washed several pounds of beach sand from the undercarriage of my Ford Bronco. The key is going slow when spraying the undercarriage to ensure all sand and debris are removed. I would highly recommend for undercarriage washing / cleaning. ... show more

  • Works great, quick shipping, reasonable price
Easy to assemble- connections are secure. Adequate water spray but not super powerful under my lifted jeep with 35" tires. Gets mud off nicely. Rolls easily, Only used once so far but seems durable. Easy to adjust by adding extensions. Used with my 2100 psi pressure washer. Would recommend. Reasonable price. ... show more

  • Works perfectly!
This seems like good quality & does what I intended. It has a nice, strong steady stream from the nozzles. I can clean all the salt from the bottom of my car in the wintertime. I'm happy!

  • Great product
Love it!! Delivery was quick as always. Product was very well packaged. Instructions were clear and easy to follow. One of the first things that I noticed was how well built it was. You could immediately tell that it wasn’t cheaply designed and built. The wheels are great quality and not some worthless plastic. It was cold the day I received it so I couldn’t hook it up and try it out. I believe it will work like it should. ... show more

  • Works pretty darn well when hooked up to a gas powered pressure washer.
The spray pattern was better than expected and the overall operation was easy to hook up and maneuver under my truck. Comes with a nice complement of extensions. Over all it is heavy duty and well constructed for this price point. I have only used it twice and don't have tons of use cases lined up, but my gut tells me it will last for years to come. ... show more

  • Westinghouse 16” water broom
Pleasantly surprised at how well this works and how easy it is to maneuver. I bought this to clean my painted pool deck since the normal surface cleaner will actually remove the paint. Used with a 3100 psi 2.5 gpm gas pressure washer, plenty of power to remove the grime, but not so much that it removes the paint. I’ll update this review if I have any failures down the road. ... show more
