Flame Resistant for Safety
The Cougar is designed with safety in mind. It features a steel nozzle with a five-foot flame-resistant hose and a fireproof three-gallon steel chamber. The patented filter system uses fire-resistant fabric rated up to 1,200 degrees Fahrenheit, and the remaining parts are all made out of thermo-plastics to withstand high temperatures.

NOTE: Never use a household, or shop vacuum to clean a fireplace, because warm embers can be hidden under ash, which acts like an insulator and can keep embers hot for days after you think the fire is out. The combination of swirling air and debris inside a flammable paper bag filter is an extremely dangerous fire hazard.

Filter System Captures the Smallest Airborne Ash Particles
The Cougar features a double filter system that ensures no ash escapes the vacuum. This system leaves your air ash free and makes the process of cleaning your fireplace simple, clean, and healthy.

Each of the system's filters is designed to trap the finest ash, and the second filter even captures sub-micron particles. This double-filter action effectively traps ash, so your air stays clear.

Clean Filters Without Removing the Lid
Your Cougar's filters can be cleaned without removing them from the vacuum, eliminating any potential mess. For a quick dust-off, simply remove the brass cap from the lid and jiggle the agitator rod from side to side to shake the filters and make ash particles fall off.

After you have vacuumed up 60 to 80 gallons of ash, your Cougar will be ready for a thorough cleaning. Just detach and vacuum the secondary and primary filters to clean them.

Three-Gallon Canister Requires No Bags
The Cougar Ash Vacuum features a cold-rolled steel canister that will hold up to three gallons of ash. This fireproof canister safely contains your ashes without bags, so you'll never need to worry about expensive and annoying replacements. Just remove the canister's lid when it's time to empty your ashes.

Removes Ash Quickly and Quietly
Thanks to its powerful, six-amp electric motor, the Cougar can suck up ash quickly and easily. What's more, specially designed motor housing makes operation as quiet as can be. In fact, the Cougar is the cadillac of ash vacuums, operating with 60% less noise than the Dustless Technologies Cheetah II.

To help speed up ash removal, the Cougar's crimped steel nozzle is designed to quickly pick up ash and leave larger debris behind--for burning at a later time. To use, just place the vacuum nozzle directly on the hearth and swipe it in a circular motion. Ash will flow smoothly through the hose without clogging.

The Dustless Technologies MU405 Cougar Ash Vacuum is backed by a one-year limited warranty for home use.

Customer Reviews

This Vacuum works great for cleaning ash out of my pellet stove.
The filter system works very well so there is no worries about the vacuum filling your room up with a fine dust.
The hose has a metal tip that does not attach to the hose so it falls off if not carried just right.

With a fat Amazon gift certificate burning a hole in my jammies, visions of a clean coal stove danced in my head. I had been lusting after one of these ash-vacs for years, and now finally, it would be mine...

Boy do I wish I had read a review like this one prior to purchasing this vacuum (which I will return tomorrow). Didn't even have to dirty it, reading the instructions was all it took. Unfortunately, it required getting in to my livingroom to figure this out, since in none of the online descriptions at various sites, including Amazon, did it mention that this unit is for FINE ASH ONLY. In other words, the steel nozzle opening, approximately the diameter of a nickel, is designed to admit fine powder ONLY, and even that in small bits with the nozzle pressed against the firebrick in a "small circular pattern", allowing the ash to "sift" into the hose incrementally. (The instructions went on to detail all the various ways the thing could get itself plugged up...)

HELLO! Has anyone out there ever heated with solid fuel full time? It would take all day to suck up ash in that manner, not to mention that burning wood/coal does not produce exclusively fine ash. For coal especially, clinkers - the molten residue of trace minerals found in anthracite coal, are part of the bargain, and are produced in such abundance that it would render this tool effectively useless for coal burners.

In addition, though the hose is metal, intimating that the odd live coal is no biggie, the filter system in this thing is CLOTH - ie. you can burn holes in it with live material. Then it leaks. Right.

I'll have my 200+ bucks back and suck my ash chamber out with my shop vac, thanks - especially since the stuff would have to be cool anyway. (You can buy fine particle filters and bags at Home Depot). So much for my simplified stove cleaning fantasies...Oh well.

You know I read and yes, re-read those other reviews prior to going out and purchasing mine. I on one hand was using my own personal vacuum (wind tunnel hoover) to pick up the ash that my fireplace insert pellet stove was producing and I clean mine everyday. Using a ordinary vacuum is insane to say the least and messy so I finally went out and looked at the vacuums and came to this one online at Amazon but I went to my local fireplace center and purchased it there - to avoid shipping cost and they wanted nearly $270.00 for it but I got it at the same price as Amazon just no shipping - Well I LOVE IT - no mess not too loud - (the dog barks at my regular vacuum) no dog barking at this one. The flexible tube I have no issue with as of yet - it moves with ease and no cracking - no problems, no mess - I must tell you that it does not come with tools and I use and need the tools so I purchased them separetly well dont use your own vacuum tools they fit and why spend the $15.00 as you have no where to store them on the vacuum anyways. This vacuum is intended to pick up ash - not the hard stuff that looks like volcanic stuff that sits in the pan - just the ash and for us, no problem it does the job that my vacuum was dying over.

If you have a pellet stove, this vacuum is an absolute must. I don't really see the benefit of using it for a fireplace, though; we have a wood-burning furnace and continue to use a shovel to clean it out. The crimped nozzle design and the idea of vacuuming with the nozzle against the firebrick to only pick up ash and leave solids behind sounds good, in THEORY. The problem is that the solids quickly build up around the nozzle from the suction and any particles too large to fit inside the nozzle get stuck there the second you lift the nozzle to position it elsewhere. This design would work if there was perhaps a screen fitted over the nozzle to prevent this from happening.

To clean a pellet stove, though, it is absolutely ideal. Pellets are small enough to get picked up by the nozzle without any problems. Also, as anyone with a pellet stove knows, these stoves are a real nightmare to clean by hand because of the many parts involved that need to be cleaned on a regular basis - not only do you have an ashpan to empty, you have to clean a burnpot, air inlet chambers, heat exchanger tubes, etc. It used to take me over an hour to try and clean this with a brush and small shovel, and it always made a huge mesh. This vacuum has really simplified this chore and made it a breeze!

I purchased this ash vacuum less than one month ago for use with a pellet stove. In that time, and with only light use, the "flexible" hose has cracked, the motor is making a funny noise as it winds down, and the suction is significantly decreased long before the canister needs emptying. I would never buy this again, and would recommend to anyone needing an ash vac to look elswhere.

We purchased an ash vacuum cleaner for our pellet stove on the advice of a friend. He mentioned that he used a Loveless Ash vacuum and was well pleased. So we decided to shop online and found a good deal on one. We were happy with the order process, pricing and the speediness of the delivery, but none of that could compare to our overall pleasure for the product itself.

This thing works wonders, was quick to put together and great on function. I'd recommend this product to anyone that needs to vacuum up ash and as not tried it. No conventional vacuum can do what this can - I originally tried using one and made a major dust storm in the house! No fun cleaning that one up! With this Loveless vacuum, there is no dust in the air, no concern about slightly hot "coals" with the metal hose, so no worries at all.

Great product!
