The Cougar Ash Vacuum comes from the leader in Ash Vacuum technology Loveless Ash and Dustless Technologies. The patented design gives you the safest, most secure way of cleaning ashes out of fireplaces, pellet stoves, grills or any device that creates ash. Its all-metal construction and fire resistant filters make the Cougar Ash Vacuum the right tool for a very important job. What good is an ash vacuum if it spews ash particles into the air whenever you flip the on switch? Unlike other ash vacuums, the Cougar has a proprietary coating on its primary filter that captures extremely fine particles to keep the ash inside the canister. It does not cough out dust when first turned on. You can also clean the primary filter without opening the canister by jiggling the agitator rod located on the top of the lid. Another innovative feature that helps keep the ash inside the canister so your home stays clean and ash free.

  • Patented Heat / Fire-Resistant Filters
  • A proprietary coating on the primary filter captures the extremely fine particles to keep ash inside the canister so it does not cough out dust when it’s first turned on
  • Flexible, flame resistant 5 foot hose
  • 3 gallon capacity canister is made from cold-rolled steel
  • Powerful 6 Amp Electric Motor
  • Works with the following tools and accessories: Model # 4P22 Ash Vacuum Cleaning Tool Package, 3 Pieces. Includes brush tool, pellet stove hose, crevice tool. In case the need for replacement filters, use Dustless Technologies Replacement Primary and Secondary Filter Package, Model # 2F22.

Rated 5 out of 5 by Great ash vac... We've had this ash vac for a year now and have had no problems at all with it. Works great, has really good suction and is easy to empty. Pretty much maintenance free. One person complained that the hose clogged.....it does if you suction up pellets....which it tells you not to do! You can't go wrong with this ash vacuum!!

Rated 5 out of 5 by Does what others wont PROS: It does the job its intended for, to vac ash and smalls partials. We use ours for our pellet stove. No dust, easy to assemble, quitter then a shop vac and some Home Vacuums! CONS: I'd like to have seen a holder for the hose, thats it! Final thoughts: So far, we've used it 5 times, with no need to empty it yet. You can't go wrong with this unit and I've not had one problem at all with it. December 11, 2010
Rated 5 out of 5 by Cougar ash vac This vac is well worth the money ! I use this vac once or twice a day while pellet stove is going,just dial back the pellet feed and let the flames go down then start vacuuming out the hot ash(no red or really hot ambers)but it handles really hot ash just fine and you won't see any ash or dust belching out the exhaust from this vac either. With good pellets I have been able to run the stove 3 weeks straight without shutting down to vac the stove out. Yes its expensive , but its worth every penny . April 10, 2012
