Rotobrush Register & Grille Cleaning: The Fort Lauderdale Owner’s Guide
If you own a Rotobrush system and the register and grille cleaning attachment has stopped doing its job, we stock compatible parts here in Fort Lauderdale and typically install them for $145 to $385 depending on your model and what actually failed. Most jobs are done in under an hour once the right part is in hand. Where owners usually catch it first is at a supply register in a bedroom or hallway: the brush spins but doesn’t make contact, or the air-driven head stops turning entirely because a bearing finally gave out.
We’re an independent service company, not a Rotobrush affiliate. That means we tell you straight whether the OEM part is worth the money or a quality aftermarket equivalent will do the same work for less. Roy Castellanos has been running duct systems in Fort Lauderdale long enough to know which Rotobrush parts fail from honest wear and which ones fail because Florida humidity got to them first.
Which Rotobrush Models This Applies To
Rotobrush has made several generations of register and grille cleaning attachments over the years, and they are not interchangeable the way some owners assume. The older manual brush kits with the wooden handles take a completely different head assembly than the later air-driven models that attach to the main vacuum hose. If you’re looking at a Rotobrush aiR+ or the R5000 series, the register cleaning attachment typically runs off the same negative-air source as the main brush system, which means the coupler size has to match exactly.
The quickest way to identify what you need: look at the coupler end of the attachment. Measure the inside diameter of the fitting in millimeters with a tape or caliper. Most Rotobrush register attachments we see in Fort Lauderdale are either 38mm or 50mm couplers, and that measurement alone eliminates half the wrong parts before you ever call. The OEM part will have a Rotobrush part number stamped near the coupler or on the body; aftermarket equivalents made for Rotobrush machines usually list the compatible series right on the packaging. One gotcha worth knowing: the register brush heads for the aiR+ line have a shorter shaft length than the older rotobrush 100 series, and installing the longer shaft on a newer machine will bind the head against the register opening. We see that mistake more than we’d like.
Styles & brands we work with




Signs Your Rotobrush Register & Grille Cleaning Attachment Is Failing
- Brush spins but no scrubbing action. The bristles on the rotating head have worn down to the backing plate. This is the most common cause we replace in Fort Lauderdale homes, especially on systems used in multiple units or across condo buildings.
- Attachment head binds or stops turning under light pressure. The internal bearing has seized, usually from fine dust working its way past the seal. Florida’s humidity turns that dust into a paste that accelerates the failure.
- Air leaks where the coupler meets the hose. The rubber or plastic coupler lip has cracked or stretched from repeated connection cycles. You’ll hear a hiss at the joint and lose suction at the register.
- Visible rust on the shaft or metal components. Salt air near Fort Lauderdale Beach and along the Intracoastal gets into everything. Rotobrush attachments stored in a van or garage near the coast rust faster than the same part used inland.
- Bristles are brittle, flattened, or falling out. Heat plus humidity breaks down nylon bristle material over time. Once bristles start shedding, the attachment is past cleaning and into replacement territory.

AfterReplacement Cost & What’s Included
For Rotobrush register and grille cleaning attachments in Fort Lauderdale, plan on $145 to $385 installed. The range breaks down like this:
- Replacement bristle head only: $145 to $190. This covers the rotating head with new bristles when the coupler and shaft are still in good shape.
- Full attachment assembly (head, shaft, coupler): $225 to $315. This is the most common job we do when the bearing has failed and the coupler is worn.
- Complete kit including extension pieces and case: $320 to $385. Only needed when multiple components have failed or been damaged in transport.
Every one of those prices is written down before we touch the part, and it does not change when the work is done. That’s The Garrison Standard, and it’s how every Hollis Air Duct location runs. The replacement itself is covered by our 365-Day Done Right Promise: if the part fails within a year, we come back and make it right at no charge, including a free second visit.
DIY or Call Us?
Replacing a register cleaning attachment is not dangerous work the way a tensioned garage spring or a live electrical panel is. Nothing on this part is under load when it’s in your hand. What an owner can safely do is clean the attachment, inspect the bristles and coupler for visible wear, and confirm the measurements before ordering anything. Where DIY goes sideways is parts matching. We’ve had Fort Lauderdale customers buy the right-looking part online, only to find the coupler is 38mm when their machine takes a 50mm, or the shaft length is wrong for their Rotobrush series. By the time they’ve paid return shipping twice, they’ve spent more than our installed price. If you want it done once and done right, call us at (754) 354-3644 and we’ll match the part to your machine before we ever show up.
FAQs
In Fort Lauderdale’s humidity and salt air, expect 18 to 36 months of regular use from the bristle head, and 3 to 5 years from the full assembly before the bearing or coupler typically fails. Machines used in coastal buildings near the beach skew toward the lower end. Call (754) 354-3644 and we’ll give you an honest read on whether yours is worth another season.
Sometimes. If the bristles are worn but the bearing and coupler are intact, a replacement head for $145 to $190 gets the job done. If the bearing has seized or the coupler is cracked, rebuilding costs more than a new assembly, so we’ll tell you to replace it. Either way, the price is written before any work starts.
Most Rotobrush register attachment replacements take under an hour once the correct part is on the truck. We’ll confirm your model and measurements before we arrive so there’s no second trip.
We stock the most common Rotobrush attachment heads and couplers on the truck, and for specialty series we source the part the same week. If we need to order it, we’ll tell you that on the first call, not after we’ve arrived. We also handle parts for other major brands including Lennox, Trane, and Carrier if your system uses a mix.
Clean ducts move air. Everything else is just noise. Call Hollis Air Duct Fort Lauderdale at (754) 354-3644 for a free estimate on your Rotobrush register and grille cleaning replacement, and we’ll quote the number before we touch the part.
