After using a shop vac for years I bit the bullet and went for the cougar ash vac, the shop vac works well but after having the filter bag rip and fill the house with ash, [ where the bag goes on the cardboard separated from the bag, the wife was pissed !! ] and with new carpet being installed later next week I went for the ash vac, I heard all about how loud, not much power etc. all I can say is its not as loud as the shop vac and yes the suction is a little less but not that much, picked up the acc. kit with it and I'll say cleaning is soo much easier now and does a better job. I cleaned out both stoves in less time it took to do one. both stoves had over 6 bags burned since last time I did a minimal cleaning and it didn't loose any suction, so all in all I'm impressed so far with it, that and after the blow out with the shop vac bag I'd say it was a good investment. The small attachments in the kit I got made doing the fines box, igniter clean out, fan's and all the little nooks in both the 52 and 68 was a snap to do, I'll never go back to the shop vac , well I'm using it to make it clean up after its self !! lol,,,,,
