Although, I've only used it to wash my van, I'm satisfied with the pressure. Now, when I use it to prepare my deck for new stain, I'll know it's real value.
I was presently surprised how well this product works. I also purchased the power brush attachment which I highly recommend. I cleaned a 100 square foot patio that was very dirty and had quite a bit of mildew on it in 20 minutes. The concrete looked very clean and bright when finished. Easy to put together and use. Very happy with this purchase!
