If you just shined a flashlight under your lint trap and saw what was down there, you already know why you are here.
If you have not done it yet, do it before you read another word. Pull the trap out. Turn your phone flashlight on. Look at the bottom of that slot.
What you find in there is not supposed to be there. And nothing in your dryer manual ever told you it was building up.
My name is Sarah. I cleaned my lint trap before every single load for 17 years and never missed one. Then one afternoon my dryer stopped keeping up and I shined a flashlight into that slot for the first time. I spent a week looking for something that could actually reach what I found down there.
There was only one thing built for it. This is what it is and why nothing else on the market does what it does.
It is the Lumora's Dryer Vent Cleaning Attachment. It is the only attachment on the market built specifically to reach the cavity below your lint trap slot — the place your lint trap sits above and never cleans. It attaches to the vacuum you already own. The nozzle fits through the lint trap opening. The flexible hose reaches the base of the cavity. The built-in guide screen pulls lint directly into your vacuum canister rather than pushing it around.
You pull your lint trap out the same way you do before every load. You insert the attachment. You run your vacuum for about a minute. That is it. No service call. No scheduling. No taking anything apart.

The lint trap catches a fraction of what each load produces. The rest follows the airflow down into the cavity below the slot and settles there every single time you run the machine. Over months and years it compresses against the heating element area. The dryer keeps running. Clothes keep drying. Nothing on the outside tells you anything is wrong until drying times start climbing or something worse happens.
The U.S. Fire Administration identifies lint accumulation inside the dryer as the leading contributing factor in residential dryer fires. Not the exterior duct in your wall. The interior cavity. The part below the trap. The part that the retail cleaning product industry has never built a tool for.
A professional service call to clean this cavity costs $150 to $200 per visit. Twice a year. There was no at-home solution for this specific opening until Lumora's built one.
The cavity below your lint trap has a specific geometry. The slot opening is narrow. The cavity is deep. The base of it curves. Reaching it requires something the right diameter to enter the opening, the right length to reach the bottom, and flexible enough to follow the interior shape.
Lumora's is the only attachment built to those exact dimensions for that exact slot. You attach it to your existing vacuum, drop it into the lint trap opening, and the built-in guide screen does the rest. Users regularly pull out enough lint to fill a kitchen trash bag on their very first use.
Pull the flammable hidden lint out of the cavity your lint trap was never reaching. The same lint the U.S. Fire Administration identifies as the leading cause of dryer fires. A few minutes once a month gives you real peace of mind every time you run a load.
The flexible hose curves and navigates the interior slot that rigid tools cannot reach. It goes deep into the cavity below the lint trap and stays there until the job is done. No other attachment on the market is built for this specific opening.
Attaches directly to your existing vacuum hose. Dyson, Shark, Bissell, shop vacs, stick vacs. You do not need to buy anything else. Pull out your lint trap, insert the attachment, run your vacuum for a minute.
The built-in guide screen is what makes this work where nothing else does. It keeps the lint flowing into your vacuum canister rather than breaking loose and resettling back into the cavity. One clean pass. Done.
A professional interior dryer cleaning costs $150 to $200 per visit, twice a year. With Lumora's, you do it yourself through the lint trap slot in under two minutes. No scheduling. No waiting around. No recurring bill.
This is the only tool of its kind on the market. It is built to do one job correctly, through the opening you already open before every single load, with the vacuum you already own.
The lint trap catches what it catches. The rest has been falling into the cavity below it since the first load you ever ran in that machine. When people use Lumora's for the first time after years of faithfully cleaning their lint trap before every load, the amount that comes out stops them cold.
It is not a maintenance problem. It is a geometry problem. The lint trap was never designed to reach the cavity below it. Nothing was, until now.
"I cleaned my lint trap before every load for 11 years. First time I used this, my vacuum canister was half full. My dryer has run a full load in one cycle every single time since. I genuinely did not know this cavity existed."

Every load deposits more into that cavity. Every week it builds. The dryer works harder to push air through the accumulation. Drying times climb. Electricity usage goes up. The machine runs hotter. Most homeowners assume the dryer is just getting old and start pricing replacements.
It is not getting old. It is getting choked from the inside. And the opening to the problem has been right there every time you pulled out the lint trap.

Lumora's is built from flexible polymers that navigate the interior slot without wearing down or losing shape over time. The guide screen is integrated, not removable, so lint goes into the canister every pass. The fit on the vacuum hose is secure enough that the attachment does not slip mid-use.
It is designed to do this one job correctly, every month, for years. Because the cavity does not stop filling up just because you cleaned it once.
People who have never thought about the cavity under their lint trap are finding out about it for the first time when they use Lumora's. Here is what they are saying.
Heather M.
(Verified Buyer)I cleaned my lint trap before every single load for years and had no idea what was building up underneath it. The first time I used this I could not believe what came out. My dryer has dried everything in one cycle since. Nothing else on the market does what this does.

Katana L.
(Verified Buyer)I vacuum inside the lint trap slot regularly and thought I was on top of it. But my vacuum tube could not reach the base of the cavity no matter what I tried. This attachment was built for exactly that opening. Best investment ever and I have not seen anything like it anywhere else.

Greg H.
(Verified Buyer)Clipped it onto my Shark cordless and it fit perfectly. The flexible hose goes right down into the cavity and the vacuum pitch changes immediately when it starts pulling lint out. I had been looking for something that could do this for ages. Turns out this is the only one that actually works.

I had no idea this cavity existed under my lint trap. The first time I used this my vacuum canister filled up from a dryer I thought was clean. Very well made and incredibly easy to use.
My dryer dries a full load in one cycle now for the first time in years. I thought the machine was just getting old. It was not getting old. It was getting choked from the inside.
Every load you run from this point forward deposits more lint into that cavity. The longer it goes without being cleaned the more compressed it becomes and the harder it is for air to move through the machine. The dryer works harder, uses more electricity, takes longer to dry, and runs hotter than it should.
Most people who use Lumora's for the first time say the same thing afterward: they wish they had known about this years ago.
Lumora's is the only attachment built for this specific slot. There is nothing else on the market with the same dimensions and guide screen design for the interior lint trap cavity. When they sell out, there is no substitute. Check current availability before your next load.
A few things people ask before they order.
Lumora's is the only dryer vent attachment built for the interior cavity below the lint trap slot. It attaches to the vacuum you already own. It reaches what nothing else reaches. It takes under two minutes once a month.
