Works great! Significantly limits water spray back into clothing. I used it to clean pavers. I did have to use regular nozzle in areas where some pavers were very uneven, but most of the pavers cleaned very well without extra work. Works best by pulling backwards. By concentrating water within the unit, it helps easily dislodge debris from cracks. Much more gentle on the body than using only wand to clean. Faster cleaning than wand only
