I buy this after get feed up with empty my canister vacuum and suck dust , and who know what else , each time . I just could not quantify spending as much money as I do only to inhale everything I would just clean out of my house . the end result be that I vacuum less when the canister begin to get on the full side because I hate the idea of have to empty it . so that be why I buy it in the first place . as soon as I take it out of the box I be pretty thrill with the purchase . all of the accessory attach to the unit securely and I have not have a single piece pop off on it be own even when lug it up stair , down stair , and put it in the back of my car . at the same time they be easy to put on and take off when you want . the only slight exception may be the power paw and the ` wide ' attachment for the hose . I have not have any problem with they but I can see how they might cause problem . the power paw be the least securely attach and the wide attachment be the most securely attach and slightly cover by the cord when wind up . pro : where do I start ? 1 -rrb- it be powerful . this be easily one of the most powerful vacuum I have ever use . it suck the litter right out of my litter-catcher-rug that I have in front of we cat box . I use to have to shake the rug out and vacuum the litter off the tile , but now I just pop on the wide attachment for the hose and go to town . 2 -rrb- it have as all the most practical attachment include plus the power paw . this pro be just about standard . all vacuum should come with the primary attachment and this one do and they throw in the power paw which be really great for stair ... just like they advertise it to be . as for the power paw , it rotate via suction . I have a bagless with this attachment and it would lose suction so quickly -lrb- pet hair in the filter -rrb- that this attachment be useless . on this vacuum the power paw be like a freak chainsaw no matter how much hair it suck up . 3 -rrb- it be easy and fast to switch from floor to hose setting and back again . I can literally go from vacuum the floor to use the hose in 5 seconds or less and I can go from vacuum the floor to use the hose with any attachment + the extension in 10 seconds or less and it only take very slightly longer to put it all back and continue vacuum the floor . go be the day for I that I do all my floor vacuum and then follow up with the hose . now I can do everything in one pass . 4 -rrb- the floor brush can be engaged\/disengaged with the flick of a switch for easy transition from carpet to bare floor . this be the first vacuum I have own that I can do this on and I will never go back ! vacuum bare floor while the brush be spin be like ... well ... it just do not work . all it do be turn everything on the floor into tiny projectile that be launch at my foot and shin . be able to turn off the brush ... it be one of those , `` finally ! '' moment for I . what I mean be , I can finally just use the vacuum on my bare floor instead of the vacuum\/broom combo . I use to sweep the bare floor up then follow up with the vacuum to get all the corner the the broom could not clear . now , because of this feature and # 3 , just the vacuum , easy peasy . 5 -rrb- it have a hepa filter that be easy to access for removal and installation . I have not have to replace it yet but I do open it up and remove it and install it just to see what it be like . Super easy . 6 -rrb- it have a light on the base for dark corner . this be good for unlit or not-well-lit area of the room . personally , I have find this more of a novelty than something I would require in a future vacuum purchase . 7 -rrb- the bag be easy to remove and install . again , this be just about standard . the last bagged vacuum I have be a soft top -lrb- the bag be inside of a zippered bag -rrb- so it be ridiculous to get the bag out and put it back it . it be the vacuum that put I off bagged vacuum . I go to canister and do not go back until now ... over a decade later . 8 -rrb- wide track . this be just a convenient feature . wider track = less pass . I have not , as of yet , have any situation where it be too wide to fit somewhere I need it to . 9 -rrb- it be a bagged vacuum . like I say on # 7 , I have be use bagless\/canister vacuum for over a decade now . I finally get so feed up with the dust cloud when empty they and tap out the filter so I would not have to spend another $ 20 so soon . I even make a special tool so that I could attach my filter to my drill and spin the dust that be pack so tightly in there out with centrifugal force . this , obviously , just make the dust cloud during canister empty worse but if I want the vacuum to have any suction it be necessary . even then , I would lose suction steadily as I suck up the cat hair . since I do not feel like dish out $ 300 - $ 600 for a canister vacuum that `` never lose suction '' yet still deal with the cloud of nasty when I empty the canister I buy this bagged vacuum . there be still the bit of dust that poof up when you detach the bag from the vacuum and there be a possibility of dust that puff out if you compress the bag but nowhere near the amount of a canister . if you be careful , there be no dust cloud at all , which be freak awesome . no more dust mask and goggles for I while empty canister ! 10 -rrb- last minute addition after write in my con . there be a second handle low on the vacuum for carry up stair . it make it so much easier to handle ... no pun intend . con : 1 -rrb- it be loud , as with every other vacuum I have ever own . not really a true con as all vacuum be loud but it be still advisory to wear hearing protection when use it . 2 -rrb- it be kind of heavy . this be not a con for I but my wife have some trouble with it when it come to stair . 3 -rrb- the handle be not as comfortable as it could be . although not entirely uncomfortable it be not as nice as some of they other model . 4 -rrb- the light on the base be not quite as bright as it could be . at first I think that it would be a really great feature but it be not quite bright enough to make a significant difference in visibility in my opinion . they could have put a much brighter system in here quite easily . Hope this help you with you decision !
