Will It Clean It? – Tennant S9 Walk-Behind Sweeper Test!

Welcome back to Will It Clean It? – the blog where we don’t just believe the hype… we test it. Today, we’re putting the Tennant S9 Walk-Behind Sweeper to work and seeing if it truly lives up to its name.

This industrial-grade sweeper comes from the trusted folks at Robey’s Powerkleen, and it's marketed as a simple, effective solution for quickly cleaning large indoor and outdoor spaces. But… Will it clean it?

🎥 Watch It in Action Below

We put the Tennant S9 to the test on a dusty concrete floor with scattered debris to simulate a typical warehouse or shop setting.

🔧 The Setup:

We tested the Tennant S9 on:

• Concrete flooring with fine dust and grit

• Loose debris like leaves, screws, and dirt

• Indoors and near the threshold of an open garage

We let the debris settle and ran the S9 straight through the mess—no prep, no special treatment.

💡 Features We Noticed:

• Twin side brushes reach corners and edges with ease

• No cords or power required – it’s 100% manual

• Lightweight and easy to maneuver

• Large hopper picks up surprising amounts before needing to empty

• Solid build – this is not your average consumer-grade sweeper

🧪 The Results:

✅ Final Verdict: WILL IT CLEAN IT?

Yes, absolutely.
The Tennant S9 passed with flying colors—easy to use, surprisingly powerful for a manual unit, and ideal for anyone who wants commercial cleaning without the noise, cords, or maintenance of a powered machine.
