At United Rotary Brush, we know that a clean street is about more than just appearance. It’s about safety, drainage, and protecting infrastructure. One tool plays a central role in this work—main brooms.
These brooms sweep debris off the road and into the path of collection. Without them, leaves, trash, and sediment stay behind. Over time, that debris gets pushed into drains. Once drains clog, streets flood. Pavement breaks down. Property gets damaged.
That’s why we build main brooms to perform under pressure. Let’s take a closer look at how they work—and why they matter so much for drain health.
The Connection Between Sweeping and Drainage
Stormwater needs a clear path. When streets are clean, water flows freely into the storm drain system. But if trash, leaves, or grit pile up near the curb, that water backs up. It pools on the road. In heavy storms, it floods intersections and low-lying areas.
Main brooms are the first line of defense. They clear heavy debris that would otherwise sit and collect. The main brooms’ job is to sweep everything into the hopper after the gutter broom sweeps the debris from the curbline into the path of the main broom.
We design our brooms to do that job consistently—day after day, mile after mile.
How Main Brooms Work in the Sweeper System
Every part of a street sweeper plays a role. But the main broom is what makes the first contact. It rotates beneath the machine, scraping and lifting debris into the collection area.
When main brooms are worn or damaged, they miss material. They leave behind clumps that later get washed into drains. That small miss creates bigger problems.
We work with sweeper teams across the country. They rely on our brooms to sweep clean in one pass—especially before heavy rain or storm events.

Signs It’s Time for a Main Broom Replacement
No broom lasts forever. Over time, bristles wear down. Coverage becomes uneven. The broom may skip, leave streaks, or make multiple passes without fully clearing the surface.
If you’re seeing these signs, it’s time for a main broom replacement.
Delaying replacement puts the entire system at risk. It also leads to more clogged drains, more flooding, and more service calls. That costs time and money.
We make it easy to find the right broom fast. Our team helps match the exact size, type, and fit for your sweeper.
Why Fit and Quality Matter
As a long-standing main broom manufacturer, we know that details matter. Using the wrong broom size or material can lead to issues. The wrong filament size can leave behind fine dust or heavy debris.
We build brooms to match your equipment, your road conditions, and your sweeping goals. Whether you need a general-purpose broom or one built for heavy spring cleanup, we’ve got the right brooms for you.
Supporting Complete Street Sweeping Systems
Good drainage depends on full coverage. That includes curb lines and medians. If only part of the road is clean, water will still carry debris to the drain.
That’s why we also support full system sweeping. Our tube brooms handle dense debris and high-friction surfaces.
As a trusted tube broom manufacturer, we ensure every product meets performance expectations in both urban and rural environments.
Conclusion
Main brooms are more than just a part of a street sweeper. They protect roads, prevent flooding, and support clean, functional drainage systems.
When they’re working well, water flows. Streets stay dry. Property is safe. But when they wear out, it doesn’t take long for the damage to show.
