  • AMAZING!!!
Style: 16.5" Stainless Steel Surface Cleaner
This surface cleaner is AMAZING! It is very sturdy and easy to connect and use. I have already used it for 2 days and it has saved me a ton of time and soreness!!! It cleans evenly and even on the worst areas of the deck, it only took a couple of passes to get it completely clean! I highly recommend this item!!! ... show more

  • A STAR IS BORN
Style: 16.5" Stainless Steel Surface Cleaner
Extensive research led me to the Westinghouse 16.5” stainless steel surface cleaner (my first SC). The performance leap from the standard spray gun is massive! Westinghouse delivers the best surface cleaner value: unmatched stainless steel construction at this price. The 4-wheel design is a game-changer, cleaning concrete so effectively I skipped chemical pre-treatment. Kudos to Westinghouse for an exceptional, affordable product! ... show more

  • Surprisingly Better Performance at a Lower Price
Style: 16.5" Stainless Steel Surface Cleaner
Surprisingly Better Performance at a Lower Price: I always believed higher-priced products meant better quality, but my recent experience proved me wrong. I purchased two surface cleaners: • Westinghouse 16.5” Surface Cleaner for $97.19 (with tax) • 14.5” SMX ProMax for $152.87 (with tax) I used both to clean my driveway. To my surprise, the Westinghouse not only cost $55.68 less but also performed better. It cleaned more evenly, felt steady, and gave me more confidence in its durability. The SMX ProMax vibrated so much while running that it felt unstable and seemed like it might break. I ended up returning the ProMax and keeping the Westinghouse. This experience really changed how I think about product pricing and value. Sometimes the less expensive option is the smarter choice. ... show more

  • Solidly built, works great.
Style: 16.5" Stainless Steel Surface Cleaner
I really like this surface cleaner. It did a great job, made cleaning the driveway of my home quick and easy. The construction is solid, and I appreciate that it has wheels, it made it so much easier to use over the plastic models that kind of just "floats" over the surface of the ground.

  • Surface Cleaner:
Style: 16.5" Stainless Steel Surface Cleaner
Why did you pick this product vs others?: This product worked well on a cement patio in areas that were not heavily soiled but struggled to adequately remove residue from bushes that settled on the patio. It moves with great ease.

  • So worth the money
Style: 16.5" Stainless Steel Surface Cleaner
Just used the Westinghouse 16.5" Surface Cleaner for the first time and I’m seriously impressed. The stainless steel feels tough and high-quality—definitely not cheap plastic like some others I’ve tried. The rotating wheels are a game changer. It moves super smoothly without me having to fight it the whole time. Cleaned my patio and driveway way faster than I expected, and it left everything looking almost brand new. If you're on the fence, go for it. Totally worth the money. ... show more

  • Powerful Surface Cleaner
Style: 16.5" Stainless Steel Surface Cleaner
Easy to use, comes assembled and ready to go. Attached this to my 2400 PSI pressure washer and had no issues. Used over pool deck concrete surface area. Old grime came off with good results. Some cleaning agents on the surface may have made the process even faster. Large head design good for efficient cleaning; on the downside of course is it wont fit into tight areas - but this is expected. Casters work well, not overly heavy. ... show more

  • A SOLID Upgrade!
Style: 16.5" Stainless Steel Surface Cleaner
An absolute solid unit over my Generac. I use a Generac pressure washer so thinking that I had to stick with brand surface cleaner I was wrong. Not only bigger, made from high quality steel, the wheels made a night and day difference versus not having any. I feel like it’s not a battle trying to keep the unit on the ground like the plastic one. And the wheels allow for even glides. I came across this one based on a lot of reviews and review sites and I got a great one. Would love in the future a pro line version like the pros use but $90 vs $900+ for what I do doesn’t justify. Have my neighbors wanting one now. Cannot find any negatives, I can’t say the price because my Generac years ago was $60+ and for about $30 more I feel like the Westinghouse is a great deal. Not much splashback and have no negatives unless you’re worried about weight over a plastic one. Although it makes up for it being on wheels, it is significantly heavier versus the plastic ones so that may be a downside but honestly it makes it feel more solid doing driveways. ... show more
