Your operator has already scrubbed the east corridor, the cafeteria and the long hallway past the gym, and there's still the whole main concourse to go. A loaded 20-inch scrubber weighs around 350 pounds, and on a brush-assist machine the operator's arms and back are what keep it moving, turning and backing out of corners.

The machine stops when the operator lets go of the drive lever, which is exactly what you want in a hallway full of doors. Lift the squeegee before you back up, or you'll fold the blade. And the pad holder comes in the box, but a scrub brush doesn't, so if you want a brush rather than pads, add one to the order. Tornado lists six options, from a soft polypropylene brush for normal floors to a grit brush for heavy soil.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"column\" style=\"text-align: left; padding-top: 3%;\"\u003e\n\u003cimg class=\"center-pic\" loading=\"lazy\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0862\/0883\/9984\/files\/tornado-bd-20-11lt-traction-drive-scrubber-close-up-control-panel.webp?v=1790375746\u0026amp;width=800\" alt=\"Close-up of the Tornado BD 20\/11LT traction-drive walk-behind scrubber control panel\" width=\"800\" height=\"800\" style=\"max-width: 100%; height: auto; border-radius: 1rem;\"\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003chr style=\"width: 70%; border-top: 2px solid #ccc; margin: 20px auto; text-align: center;\"\u003e\n\u003ch2 class=\"product-header-text\" style=\"text-align: center;\"\u003e\u003cspan\u003eWhy You'll Love the Tornado BD 20\/11LT Walk-Behind Floor Scrubber\u003c\/span\u003e\u003c\/h2\u003e\n\u003cdiv class=\"container\" style=\"align-items: flex-start;\"\u003e\n\u003cdiv class=\"column\" style=\"text-align: left;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eTraction drive with a 0.16 hp motor.\u003c\/strong\u003e The machine moves itself, so long corridors don't wear out your operator.\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cspan\u003e\u003cstrong\u003e48.5 lbs of brush pressure at 155 RPM.\u003c\/strong\u003e Enough bite to lift sticky soil in one pass instead of smearing it around.\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cspan\u003e\u003cstrong\u003e11-gallon solution tank.\u003c\/strong\u003e Paired with the 12-gallon recovery tank, it means fewer trips to the sink between passes.\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eUnder 70 dB.\u003c\/strong\u003e Only a little louder than normal conversation (around 60 dB), so you can scrub while the building is open.\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eTool-free squeegee and brush changes.\u003c\/strong\u003e Swap a worn blade or brush in the closet instead of waiting on a service call.\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eOn-board charger.\u003c\/strong\u003e Park it by a 120 V outlet at the end of the shift, plug in, and it's ready tomorrow.\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"column\" style=\"text-align: left; padding-top: 3%;\"\u003e\n\u003cimg class=\"center-pic\" loading=\"lazy\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0862\/0883\/9984\/files\/tornado-bd-20-11lt-traction-drive-scrubber-close-up-brush-deck.webp?v=1790375746\u0026amp;width=800\" alt=\"Close-up of the Tornado BD 20\/11LT traction-drive walk-behind scrubber 20 inch brush deck\" width=\"800\" height=\"800\" style=\"max-width: 100%; height: auto; border-radius: 1rem;\"\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003chr style=\"width: 70%; border-top: 2px solid #ccc; margin: 20px auto; text-align: center;\"\u003e\n\u003ch3 class=\"product-header-text\" style=\"text-align: center;\"\u003e\u003cspan\u003eSetup, Brushes, Daily Care and Parts\u003c\/span\u003e\u003c\/h3\u003e\n\u003cdiv class=\"container\" style=\"align-items: flex-start;\"\u003e\n\u003cdiv class=\"column\" style=\"text-align: left;\"\u003e\n\u003cp\u003e\u003cspan\u003eYour BD 20\/11LT ships on a pallet at about 205 lbs, in a 46 x 26 x 47 in carton.
