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 Register & Grille Cleaning: The Austin Owner’s Guide
Rotobrush register and grille cleaning in Austin typically runs $220-$380 per system when performed as a standalone service, or $95-$145 when bundled with a full duct cleaning. We stock the full Rotobrush register and grille kit on every truck, and most jobs are completed in under 90 minutes. Most owners realize something’s wrong when they notice dust blowing back out of freshly cleaned vents, or when the vacuum hose won’t maintain seal against curved or oversized grilles common in 1980s Austin builds.
We show the photo first, then talk about what needs to happen next. That means pulling a camera scope to verify debris load behind the register before we quote anything in writing.
Which Rotobrush Models This Applies To
The register and grille cleaning attachment set fits the Rotobrush BrushBeast series (all M1 through M4 motors), the Rotobrush aiR+ XP, and the legacy Rotobrush Classic models manufactured after 2012. The critical compatibility point is the quick-connect collar diameter: BrushBeast units use a 2.5-inch collar, while aiR+ XP and Classic post-2012 use a 2-inch collar. The wrong collar won’t seat, and forcing it cracks the plastic yoke.
To identify your model, check the data plate on the vacuum motor housing, not the brush head. The plate lists the serial prefix: BB for BrushBeast, AIR for aiR+ XP. If the plate is worn off, measure the collar outer diameter with a tape measure. We carry both collar sizes on every CleanRun truck, plus the adapter bushing for the rare 2010-2011 transitional unit.
OEM Rotobrush register and grille kits run $140-$180 wholesale. We also stock a quality aftermarket equivalent from Guardsman that meets the same flex-whip and brush-durometer specs at roughly 60% of OEM cost. Most Austin homeowners choose the Guardsman equivalent; the only functional difference is the warranty period, 2 years versus 5 years on OEM. CleanRun is an independent service provider, not affiliated with Rotobrush.
Signs Your Rotobrush Register & Grille Cleaning Is Failing

- Dust redepositing on furniture within 48 hours of cleaning. The register brush head has worn past its 1.5-inch bristle length, so it’s stirring debris rather than lifting it. In Austin’s caliche-heavy soil, this wear accelerates because the grit acts like sandpaper on nylon bristles.
- Vacuum hose losing seal at the grille edge. The foam gasket on the register attachment has compressed or torn. Without seal, you’re moving air around the room, not extracting from the duct. We see this most in Tarrytown and Clarksville homes with ornate cast-iron grilles that have sharp back edges.
- Brush motor bogging down or tripping thermal overload. The flex whip is kinked internally, usually at the first elbow past the handle. The kink increases amp draw, which overheats the motor. This is a gradual failure: first the motor sounds labored, then it cuts out entirely until it cools.
- Uneven cleaning pattern leaving stripes of debris. The counter-rotating brush assembly has lost synchronization, typically because the drive pin on one head has sheared. The remaining brush spins at full speed while the other freewheels, creating a striped pattern visible on the photo record.
- Plastic yoke cracking at the collar connection. Overtightening or collar mismatch stresses the yoke. Once cracked, the attachment wobbles and eventually separates during operation. In the July heat of an Austin attic, this plastic becomes more brittle and prone to fracture.

AfterReplacement Cost & What’s Included
| Service | Price Range | What’s Included |
|---|---|---|
| Register & grille cleaning, standalone | $220-$380 | Full attachment set, camera inspection of 3+ runs, documented photo record |
| Register & grille cleaning, bundled with full duct cleaning | $95-$145 | Attachment set, integrated into existing scope and photo record |
| Yoke or collar replacement only | $85-$120 | Part, labor, re-test of seal integrity |
The range depends on register count, grille type (standard stamped metal versus ornate cast or wood), and accessibility. Second-story ceilings with popcorn texture take longer to protect and restore. Every price is written before work starts under Haven Standard Clause 1. The 365-Day Done Right Promise covers labor and parts: if the attachment fails or the seal doesn’t hold, we return and make it right. We also service Lennox, Trane, and Carrier systems with equivalent documentation standards.
DIY or Call Us?

What you can safely check yourself: verify the collar size, inspect bristle length (replace if under 1.5 inches), and look for visible cracks in the yoke or gasket tears. These are no-tools observations.
Where DIY goes wrong: the flex whip kink is internal and not visible without disassembling the handle, which voids the motor warranty. The counter-rotating brush synchronization requires a torque wrench to set properly; hand-tightening guarantees premature shear. And any work on the vacuum motor housing involves 120V electrical connections that should be handled by a technician. We don’t recommend homeowners open the motor compartment.
If your Rotobrush attachment is showing any of the five symptoms above, call (737) 243-9544. We’ll pull the camera scope, show you what’s actually in the duct, and put a written price in front of you before any work starts.
FAQs
In Austin’s climate, with caliche dust and high summer attic temperatures, expect 3-4 years of residential use or roughly 150-200 cleaning cycles. Commercial use cuts that in half. The bristles wear faster than the mechanical components. Call (737) 243-9544 and we’ll measure yours during the camera inspection.
Individual components can be: a torn gasket, a cracked yoke, or a worn brush head. But if the flex whip is kinked or the motor housing is involved, replacement is more reliable than repair. We stock components and full kits, so we can offer either option with the price difference in writing. Call (737) 243-9544 for a free second opinion on any repair-versus-replace question.
Typically 45-75 minutes for a standard residential system with 8-12 registers. Ornate grilles, high ceilings, or accessibility issues add 15-30 minutes. The camera inspection and photo record are included in that time, not extra. We don’t quote time; we quote the completed job with a written price.
We stock both OEM Rotobrush and Guardsman equivalent register and grille kits on every truck, in both collar sizes. No ordering delay. If your model is the rare 2010-2011 transitional unit, we carry the adapter bushing as well. Tomas Reyes verifies stock levels each morning; if you’re calling about a specific model, have the serial prefix ready and we’ll confirm fit before we dispatch.
