I actually just bought in and will say it is sturdy and what little I have done do far works good. I am anxious to continue cleaner the other surfaces around my home.
I bought 2 of these, one for my dad, one for myself. We're both over the moon about it! Where has this been all my life? This will save me bundles of cash wasted at car washes!
Used first time over concrete,sidewalk pavers and wood deck. Wanted a product that would spread the power spray indirectly over the surface vs power sprayer wand which can be too direct causing damage. Power level from power sprayer is important. My 2.6 gas sprayer did a good job removing one year's worth of grime but had to go over the area several times for built up grime.
