It vibrates in tiny circles, so there's no torque pulling the machine sideways the way a big disk can, and the square front edge gets into corners a round brush leaves for the mop. Pair that with a traction drive and your operator is steering, not wrestling, which matters on a two-hour route.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eNow the honest part. This is a big walk-behind: 60 inches long, 39 inches across the squeegee and 348 pounds before four batteries go in. Measure your doorways, elevator and storage spot before you order. If most of your square footage is small rooms, the OB 20\/14 will get more use. And on finish removal, Tornado says the high-speed orbital action can strip without chemicals. I'd treat that as something to test on your own floor, with the right pad, before you promise a client a chemical-free strip.

An orbital head moves a flat pad in very small, very fast orbits, here 3,530 times a minute. The result is a lot of scrubbing action with less solution on the floor, which is why Tornado says the OB 28\/20 cuts water and chemical use in daily cleaning and dries faster.

The operator manual, though, has no stripping procedure, and for everyday scrubbing it calls for a low-foam detergent. How well a water-only strip works depends on the finish, how many coats are down and the pad you use. If stripping is the main reason you're buying, tell us your finish and floor type first and we'll check with Tornado before you order.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 class=\"product-header-text\"\u003e\u003cspan\u003eHow to Set Up and Care for Your OB 28\/20\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eSweep or dust mop first; the manual is clear that the scrubber isn't for loose debris. Fill the solution tank through the large fill port, watching the sight tube, and use a low-foaming, non-flammable cleaner. Fit the pad by raising the base with its switch, sliding the pad underneath and lowering the base onto it. Turn the key, switch on the vacuum, lower the head and squeegee, and squeeze the drive levers: the pad and solution start as the machine moves and stop when you let go.

Clean the inline solution filter every week or so, and close the solution valve first or the tank drains out through it. The rear squeegee blade has four usable edges, so flip it before you replace it.
