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.

AfterRotobrush Dryer Vent Cleaning in Fairfax: What to Know First
CleanRun provides independent Rotobrush dryer vent cleaning in Fairfax with written pricing delivered before any work begins, typically scheduled within 3-5 business days. Most Rotobrush vent jobs run $195-$385 depending on line length, accessibility, and whether the run needs rerouting. We photograph every section of duct before we quote a dollar, and every customer receives that photo record as part of the standard job file.
This page is for Fairfax homeowners who own Rotobrush air duct or dryer vent equipment and need service from a technician who knows the difference between a Rotobrush brush-and-vac system and a standard dryer vent cleaning. We are not affiliated with or authorized by Rotobrush. We service what you own because we’ve worked on these units since they started appearing in Northern Virginia homes in the mid-2010s. If you’re seeing longer dry times, a hot laundry room, or the Rotobrush unit itself pulling weak suction, call (571) 526-0015 for a free estimate with written pricing.
How Rotobrush Products Fail - and How We Fix Them
- Rotobrush BrushBeast and aiR+ models: stripped flex-shaft couplings. The 1/4-inch flexible drive shaft that spins the brush head through the vent line can strip at the motor coupling after roughly 150-200 hours of runtime, especially in Fairfax’s older split-levels where vent runs exceed 25 feet with multiple elbows. The motor runs but the brush stalls in the duct. We replace the coupling with a hardened steel aftermarket unit rated for 400+ hours, or source OEM if the homeowner prefers. We test torque at the register before we leave.
- Rotobrush DuctMaster series: premature HEPA filter loading in high-humidity seasons. Fairfax’s July-August humidity averages 65-70%, and the DuctMaster’s compact HEPA loads faster here than in drier climates, choking airflow and leaving lint in the vent line. We stock the Abatement Technologies HEPA-500 as a backup negative-pressure extractor on DuctMaster jobs, and we photograph filter condition at start and finish so the homeowner sees the difference.
- Rotobrush dryer vent brush kits: backward-installed brush heads on 4-inch rigid pipe. The standard 4-inch nylon brush is directional. If a previous installer ran it backward through a rigid aluminum run, the bristles feather rather than sweep, compacting lint at elbows. We pull the camera first to check bristle orientation marks on the duct wall, then re-run with a reverse-thread brush head or switch to a Nikro 860806 skipper ball for impacted sections.
- Rotobrush vacuum motors: carbon brush wear causing intermittent suction loss. The Lamb Ametek motors in pre-2019 Rotobrush units show brush wear at 800-1,000 hours. Suction drops, dry times climb, and the homeowner assumes the vent is clear because the machine is running. We meter vacuum static pressure at the tool port; if it’s below 80 inches of water lift, we flag the motor issue and give the homeowner a written option: motor rebuild, replacement, or separate vent cleaning with our Nikro HP20 gas-powered unit.
- Rotobrush vent lines: bird guard omission on second-story through-wall terminations. Rotobrush systems don’t include termination hardware. In Fairfax neighborhoods like Mantua and Kings Park West, we’ve found starling nests blocking 4-inch terminations that never had a guard installed after the original Rotobrush cleaning. We fabricate a stainless guard with 1/4-inch mesh, caulk the perimeter with high-temp silicone, and photograph the seal. Haven Standard Clause 6: Documented Completion.
Our Rotobrush Dryer Vent Cleaning Process
- 1
Camera inspection before touch. We run a color inspection camera from the exterior termination to the dryer connection, or reverse if access dictates. The camera goes in first. Then we talk. You see what we see on the tablet before we write a price.
- 2
Written scope and pricing. We deliver a single-page scope with line-item pricing: inspection fee (waived if work proceeds), cleaning labor, parts if needed, and any rerouting. Haven Standard Clause 1: No work starts without a signed written price.
- 3
Equipment selection based on duct construction. Rotobrush brush-and-vac for flexible foil or semi-rigid lines in good condition. Nikro skipper ball and reverse-air ball for impacted rigid lines. Abatement Technologies negative-pressure HEPA for homes with finished basements where dust control matters.
- 4
Cleaning and real-time verification. We clean section by section, camera-checking after each 10-foot run. If we hit a blockage we can’t clear, we stop and show you. No surprise discoveries after the price is signed.
- 5
Airflow test and photo record delivery. We measure exhaust velocity at the termination with a vane anemometer. Target is 1,000+ FPM for gas dryers, 800+ for electric. Before-and-after photos of every section, plus the airflow reading, go into your job file within 24 hours.
- 6
365-Day Done Right Promise activation. The written guarantee goes into the same file. If dry times climb again within a year, we return and make it right.

Why Fairfax Homeowners Call CleanRun Air Duct Cleaning Fairfax for Rotobrush Work
We’ve been in Fairfax homes since 2013, and Rotobrush equipment has been part of our regular workload since these units became common in new construction and retrofit jobs across Northern Virginia. Tomas Reyes, our owner, trained on building systems in Queens and built this crew around the idea that a customer should see the problem before paying to fix it. That means the photo record isn’t a marketing promise; it’s the first step of every job.
Our technicians carry Rotobrush-compatible parts and also work on Lennox, Trane, and Carrier integrated systems when the dryer vent ties into a larger HVAC configuration. The 365-Day Done Right Promise is in writing on every invoice, not a website footnote. Background-checked, uniformed crews. License number published where you can verify it. And if you have a competitor’s written estimate, we’ll put ours next to it for free under our Second Opinion policy.
FAQs
No. As an independent Rotobrush service provider, we use warranty-safe practices: OEM or equivalent-spec parts, no modification to factory wiring or safety controls, and documentation of serial numbers and part sources for your records. Rotobrush warranties cover manufacturing defects, not who performs routine maintenance. We note any existing warranty status on your written scope so you have full transparency. Call (571) 526-0015 if you’d like us to review your unit’s warranty position before scheduling.
The clearest sign is suction strength at the tool port: if the motor sounds normal but the brush head lacks torque, or if the vacuum hose pulls weakly at the register boot, the issue is likely mechanical (coupling, motor brushes, or HEPA loading) rather than a dirty vent. We meter static pressure and photograph filter condition during our free estimate to separate vent blockage from equipment failure. Call (571) 526-0015 and we’ll diagnose which it is before quoting either service.
We stock common Rotobrush wear items: flex-shaft couplings, brush heads in 4-inch and 6-inch, HEPA filters, and carbon motor brushes. For less common parts, our Fairfax warehouse receives daily deliveries from Baltimore-area distributors. If a part must be ordered, we give you a written timeline before you commit, and we don’t charge storage or return-trip fees. Most Rotobrush jobs in Fairfax complete in a single visit.
We answer this with numbers, not pressure. If the repair exceeds 40% of replacement cost and the unit has over 1,500 runtime hours, we show you both options in writing. For units under 5 years with under 1,000 hours, repair is usually the better value. We don’t sell Rotobrush equipment, so our recommendation carries no commission bias. The camera footage and written scope make the case either way. Call (571) 526-0015 for an honest assessment.
For typical Fairfax households doing 4-6 loads weekly, every 12-18 months. Homes with long runs, multiple bends, or residents who forget to clean the lint trap after every load should schedule annually. We date-stamp your photo record and send a maintenance reminder at 14 months unless you opt out. The 365-Day Done Right Promise covers workmanship; it doesn’t replace periodic maintenance. Call (571) 526-0015 to set a schedule that fits your usage.
Ready to see what’s actually inside your vent? Call (571) 526-0015 for a free estimate with written pricing. We’ll photograph every foot of duct before we quote, deliver the photo record when we leave, and back the work with the 365-Day Done Right Promise in writing.
