Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Rotobrush Dryer Vent Cleaning in Denver: What to Know First
CleanRun Air Duct Cleaning Denver provides independent Rotobrush service for dryer vent cleaning across the metro area, with most jobs scheduled within 3-5 business days and completed in a single visit. Written pricing is delivered before any work begins, every time, under Haven Standard Clause 1. A full Documented Photo Record of the vent run, before and after, is included as a standard deliverable.
This page is for Denver homeowners who own Rotobrush air duct or dryer vent equipment and need cleaning, inspection, or repair work performed by technicians who understand the brand’s specific design and failure patterns. We are not affiliated with or authorized by Rotobrush. We service the full Rotobrush lineup commonly found in Denver homes, including the BrushBeast series, the original Rotobrush Classic, and the portable RotoVent models used in tighter Capitol Hill crawl spaces and Wash Park basements.

How Rotobrush Products Fail - and How We Fix Them
- BrushBeast drive cable binding in long vent runs. The BrushBeast’s .25 hp motor and 12-foot standard cable extension work well in typical suburban ranch layouts, but in Denver’s older Baker or Berkeley bungalows with 25-foot-plus vent runs to the roof, the cable encounters torque fade and binds at the first or second elbow. We switch to a sectional rod system or deploy our Nikro HP20 gas-powered unit for the full run, then photograph the cleared path.
- RotoVent portable units with clogged lint screens. The RotoVent’s compact design, popular in Denver townhomes and Highland condos, has a lint screen positioned directly behind the brush head that cakes solid in high-lint environments, especially with the longer dry cycles common in Denver’s winter low-humidity months. We remove and hand-clean the screen, then verify airflow with an anemometer before signing off.
- Rotobrush Classic vacuum motor seal degradation. The Classic’s original vacuum motor gasket hardens after 6-8 years of thermal cycling, which is accelerated in Denver’s mile-high UV exposure when units are stored in garage or attic spaces. Loss of suction at the vent port means lint is agitated but not extracted. We replace the seal with a quality aftermarket equivalent or OEM upon request, and test static pressure before and after.
- BrushBeast reverse switch failure in forward-only mode. The reverse mechanism on pre-2019 BrushBeast units strips internally when forced against a solid obstruction, leaving the brush spinning in one direction and packing lint tighter. We disassemble the drive head, clear the obstruction with manual rods, and replace the switch assembly. On warranty-active units, we document the failure mode for your claim.
- Corroded vent cap flappers on exterior terminations. Rotobrush equipment does not include the exterior vent cap, but Denver’s freeze-thaw cycles and hail impact warp or seize standard flapper caps, creating back-pressure that overloads the Rotobrush motor. We replace with a Guardsman heavy-duty cap rated for Colorado wind load and install a bird guard where the termination is accessible to nesting sparrows.
Our Rotobrush Dryer Vent Cleaning Process

- 1
Written price delivered first. We inspect the vent run length, termination type, and accessibility, then provide a fixed written price before any panel or cap is removed. Haven Standard Clause 1.
- 2
Photo documentation of the full run. Our technician photographs the interior vent condition at the dryer connection, each elbow, and the exterior termination. Here is what the camera found. Here is what it costs to fix it. You decide.
- 3
Equipment selection based on Rotobrush model and vent geometry. We match the cleaning method to your specific Rotobrush unit’s capabilities and the actual duct configuration, using OEM brushes when specified or quality aftermarket equivalents from our standard equipment roster.
- 4
Mechanical cleaning with debris extraction. The vent run is brushed under negative-pressure extraction, meaning lint is loosened and simultaneously pulled out rather than pushed deeper. We verify with a borescope at the termination.
- 5
Airflow test and final photo record. Post-cleaning airflow is measured in CFM at the exterior cap, compared against the pre-cleaning reading, and recorded in your job file along with before-and-after images of every access point.
- 6
365-Day Done Right Promise activation. The written guarantee is issued with your invoice and photo record. If airflow drops or lint reaccumulates abnormally within one year, we return and correct it.

AfterWhat Rotobrush Dryer Vent Cleaning Costs in Denver
Most Rotobrush dryer vent cleanings in Denver fall between $189 and $349 for a single-family residence, depending on run length, termination height, and whether the vent path requires rerouting or cap replacement. Here’s how the price breaks:
| Scenario | Typical Range |
|---|---|
| Standard ground-floor vent, single elbow, under 15 feet | $189-$229 |
| Second-story or roof termination, 15-30 feet, 2+ elbows | $249-$319 |
| Rotobrush drive cable extraction/repair (bound cable in long run) | $279-$349 |
| Vent rerouting or bird guard installation | $189-$249 additional |
Factors that move the price: roof access requiring ladder work, concealed ductwork behind finished basement ceilings, and the presence of nested debris requiring manual rod work before mechanical cleaning. Every price is written and agreed before work starts. Call (720) 799-2292 for your exact estimate.
Why Denver Homeowners Call CleanRun Air Duct Cleaning Denver for Rotobrush Work

Tomas Reyes and our crew have worked on Rotobrush equipment in Denver since the brand first gained traction here in the mid-2010s. We know the difference between a BrushBeast that needs cable service and one that simply encountered a poorly routed duct, and we do not charge for the latter as if it were the former.
The 365-Day Done Right Promise is issued in writing on every job, not offered as a verbal afterthought. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they arrive with the full equipment roster: Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman. We also service Lennox, Trane, and Carrier systems when the dryer vent intersects with integrated HVAC configurations common in newer Stapleton and Lowry builds.
Since 2013, we have served over 52,000 homes with a written price before every job and a Documented Photo Record when we leave. The photo record is yours to keep, not a marketing claim.
FAQs
No. Rotobrush warranties cover manufacturing defects in the equipment itself, not routine maintenance or vent cleaning services. As an independent Rotobrush service provider, we perform cleaning and repair work that does not void your existing warranty, and we document any factory defects we discover so you can file a claim directly with Rotobrush if applicable.
We stock both. OEM brushes, cables, and seals are available by request and typically add 15-20% to the parts portion of the invoice. Our standard aftermarket equivalents meet manufacturer specifications and carry the same 365-Day Done Right Promise. We state which we are using before any part is installed.
If the motor runs but suction or brush torque drops significantly under load, the unit likely needs service. If performance is normal but dry times are long, the vent duct itself is obstructed. We diagnose both during the initial inspection and show you the camera footage before recommending either path. Call (720) 799-2292 and we’ll put a written diagnosis next to any competitor’s quote under our Free Second Opinion.
Most appointments are available within 3-5 business days. We do not maintain a same-day dispatch model because proper Rotobrush service requires specific brush sizes and drive cables to be loaded based on your model and vent configuration, confirmed when you call.
You will receive dated, labeled images of the vent interior at the dryer connection, each elbow, and the exterior termination, plus the post-cleaning airflow reading in CFM. The record is delivered electronically within 24 hours of job completion and serves as proof of work performed for warranty, insurance, or resale purposes.
