Used this patio cleaner with a Karcher K5 compact pressure washer (you need a Karcher to quick connect adaptor that's not included but are readily available for a few pounds). Efficiently cleans patio slabs and much quicker than using the Karcher gun. The Vevor patio cleaner contains the spray and prevents the overspray when using the gun. I cleaned the patio in about half the time compared with using the gun. Feels really well built and sturdy, heavy weight stops it from lifting and the wheels allow easy movement unless your slabs are very uneven. Highly recommend as long as your pressure washer has enough power.

Very good but only one problem is that it rotates on its on and does not stay where you want it to be. I think it needs something to lock it so it doesn't rotates on it on.
