Unless it’s a greasy spoon restaurant I use an Orbot Vibe or Life machine. Nothing delivers better cleaning results, appearance retention and shear amount sq foot coverage. Encap is king of CGD. HWE is king of residential.What would be your "go to" for CGD / Commercial type of cleaning?
Now if you only want to HWE, a Bonzer, Zipper or If you are referencing a rotary, the RX 20 with glides can’t be beat.
