Bests & Worsts Reviews from Amazon

First off, I'm a guy. I'm a former Marine and I don't like cleaning. It gives me flashbacks of our Thursday night field day cleaning duties. But I do maintain a clean house. I've been out for a number of years and I can afford to have a cleaning crew once a week. So I don't need a full featured vacuum, but I wanted a good one for in between cleanings. I live in a small one story house. Most of my floors are hardwood or tile, but I have a couple of bedrooms with brand new dense carpet. My old Hoover Windtunnel would just not work on the new carpet, it wouldn't move when you turned on the brushes, I think the brushes would not turn in the thick new carpet, for whatever reason. It was easily ten years old and had served me well. I didn't want to spend top dollar on a full size Dyson or even a full size Shark or other maker vacuum. I was at Sam's club last week and noticed they had this model. I did my due diligence, read all the reviews on Amazon and today picked it up for $159 at Sam's. I brought it home, set it up in a minute (so easy to do,really) and set out to do my carpets. The Shark N450 did have some problems with the new carpet. It's a really dense expensive carpet and I'm sure that its just tough to vacuum these kinds of carpets. The N450 was able to get it done with some effort. The suction is very powerful and sucked up stuff that my house cleaner's vacuum (they were here three days ago) missed. The dustbin really filled up with some nasty hair and dust. I live alone and I have a German Shepherd and he sheds like all dogs, so it's something I have to deal with, and this works fine for that purpose. The rotator steering works fine. I don't really need it in my house but it works as advertised. The brush head switch is easily accessible high up on the machine and once I shut it off I did my wood floors and area rugs with ease. What is particularly easy is transitioning from rugs/carpets to bare floors since the brush roll switch is high up and you don't have to bend down to get at it. The lights work fine for shadowy areas or if you're doing low light cleaning operations :). Emptying the dust cup was very easy, but because it's new machine for me I wanted it to stay new looking so cleaned it out and air dried the parts. So easy to do I did it in my kitchen sink, took a few seconds to hose everything out. I don't see a downside for me with this purchase, especially compared to my old Windtunnel which was much heavier, took up more room, and I had to buy bags for it. If you don't need a full size vacuum, this can't be beat in my opinion. I'll tell you that I'm so glad I didn't drop $350 on the smaller Dyson.
