Save Time and Cut Costs. The Tornado 20/11L Walk-Behind Scrubber Does Both
Time is money, and the Tornado® BD 20/11L Walk Behind Auto Scrubber saves you plenty of both. This compact auto scrubber slips through standard doorways while covering an impressive 17,969 square feet per hour. That's a lot of clean floors without breaking a sweat.
Forget about floors that look clean but feel sticky. With 48.5 pounds of down pressure and 155 RPM of aggressive scrubbing action, this machine doesn't just move dirt around, but it actually eliminates it. The superior water recovery system leaves floors dry enough to walk on almost immediately.
We know training new staff can be a headache, so we love how this scrubber features intuitive controls that even your newest team members can master quickly. And when something needs attention? The no-tools-required design lets you change squeegees and brushes in seconds, not minutes.
With noise levels under 70 dB, you can clean anytime without disrupting your environment. Add the optional batteries for up to four hours of continuous cleaning power, and you've got a machine that works as long as you do.
Why cleaning teams love the Tornado BD 20/11L:
-
Double scrubbing made ridiculously simple. The conveniently positioned squeegee lever lets you raise and lower the squeegee with minimal fuss, so you can tackle those extra stubborn spots without breaking your flow.
-
Say goodbye to complicated controls. With just a few intuitive controls, even your newest team members can master this machine quickly, reducing training time and preventing costly mistakes.
-
Maintenance that doesn't make you miserable. The easily accessible, no-tools-required design lets you change squeegees and brushes in seconds rather than minutes, keeping downtime to an absolute minimum.
-
Convenience built right in. The on-board charger means no hunting for the right adapter or connection. Available with batteries (lead acid or AGM) that provide up to four hours of continuous cleaning, or without if you prefer to use your own.
-
See where you're going, not just where you've been. The low-profile design provides clear sight lines, making it easier to navigate around obstacles and into tight spaces without the usual bumper car experience.
-
Choose your drive: Available in both Brush Assist and Traction Drive models to match your specific cleaning needs and operator preferences.
