I bought this along with a Westinghouse pressure washer and used both for the first time today to clean my concrete porch and sidewalk. The surface cleaner works surprising well, leaving a noticeable clean stripe wherever I used it. It's fairly lightweight, so not hard to use. I found it worked best to push it forward, then pull it back over the same spot for effective cleaning in most areas. For a few stubborn spots I just moved the cleaner over the area a couple more time. The surface cleaner is major time saver versus doing the same area with just a spray nozzle.
I bought the plastic 15" surface cleaner for my pool pavers and front walkway. I wanted to see if it would make a difference. Unbelievable! Fantastic job! I used half the water and completed the job in half the time versus using the wand itself.
Only one fair warning though...if you are tall, you will need an extension wand to save your back:)
I had to power wash my patio and I would typically just clean each individual stone with the hose, but after using the Westinghouse surface cleaner, it completely transformed how I power wash. It was so much easier, quicker, and more efficient and the deck looks amazing!
