Okay, so, I've been looking for a vacuum so that I have something when moving into my new place. I was only really hoping to have a few certain yet important features.- No bags.- Strong suction.- At least a 6ft hose (or around there).- Fully sealed (no allergens get ejected back out).This unit met all of that & more! I won't bother going over everything that's shown since you can just read about it in the descriptions or even look up a video on the unit (I'd suggest doing simple research like that anyway). So instead, let me point out the features that surprised me or just plain pleased me to confirm. To note, I used this for about 40-60 minutes in 2 bedrooms & a hallway, all carpet (that tall stringy type), as well as a hard wood floor living room. For the carpeted area, I ran over everything the day before with what could only best be called a cheap simple store bought vacuum. Enough to do the job on hardwood & still sucks up plenty on carpet, but it isn't gonna win any prizes.1: The suction power. Let me put it this way. Just having the vacuum on, you could feel it trying to pull forward. Dragging backwards was the same. If you use this on carpet, I highly suggest you leave the main body of the unit (the engine & dust bin) attached instead of separating it from the rest of the unit. Their weight will help counter this.2: The noise. It's a vacuum, so it's gonna make noise, but it was much quieter than I thought it'd be, especially for the level of suction it has. I could have a conversation with someone sitting 10ft from me & barely have to raise my voice at all.3: The versatility. It's an upright, but you can pull the main "engine" & dustbin unit off, turning it into a handheld that has long reach & can get under furniture with just a bit of bending over. Both the head & handle have a light to see into dark spaces. You can remove the tube running from the handle to the suction head & use it that way if you so wished. Never mind the attachments that come with it.4: The instruction manual. I know, I know. "You look at the instructions?" My uncle already laughed at me for it, but I prefer to go through the manual so I can know how to put things together the first time & even find nice little tidbits. Which is EXACTLY what I found going through this one. Let me just say that not only does this show you how to put it all together, but it shows exactly how to clean everything & even perform your own maintenance. No calling the support office, no scratching your head to figure out what's wrong. Just look through the manual & it'll give you guides on cleaning, troubleshooting, why it may be doing this, etc. I LOVE when a brand actually gives you the ability to properly & fully maintain & troubleshoot the product you paid for yourself.5: The filters. Four of them total. A mesh hair filter in the collection bin, a "barrel" sponge-like filter & a finer cloth pad filter before the suction engine & then finally a HEPA filter before any air gets shunted back out. All of these sealed up with rubber rings. I checked the filters (all removable & washable by the way, so you can keep them for much longer if you take the extra few minutes to rinse them after each session or so) & was very impressed with how much they grabbed. Honestly, not gonna lie, I sat there for a moment looking at these filters & thought "... is that what I've been living in?".Now, I couldn't finish this review off without mentioning the one downside I had to this vacuum. The extra attachments. Ya know, the little tool heads that come with it & sit in slots on the back of the vacuum. I got a narrow hose head for tight spaces, a furniture head & a "pet brush" (ya know, like a little mini suction head with it's own brush roller). The first is simple & works fine. The second does it's job as much as I'd expect it to as well. The third however... Never mind the fact that the unit only has space for 2 of the 3 attachments, but the pet brush didn't even work. The reason why is just as simple. It felt cheaply made. Out of everything that came with the vacuum, these were the cheap parts. The first two, as I said, work fine since they don't have to do much. The pet brush however didn't even have a proper seal between the top & bottom half. In fact, it had vent slits in the back so that the moment I set it down (lightly I might add) onto fur covered furniture, the brush stopped moving because it was too much & could just pull in suction from those vent slits. I should also mention that this was done on fabric upholstered furniture, not any kind of leather or similar material.Thankfully, I did not buy this vacuum for pets. My parents have them, sure, but I won't. I don't need this vacuum to tackle pets. So, long & short is this. Besides the pet brush attachment not having anywhere to sit & being cheaply made, I don't need it so I'm fine with that being the cheap part. Everything else on this vacuum has already made me decide that the $300 spent on it was very much worth it.We purchased this recently upon moving into our new home. We're trying to keep it as nice as we can with kids and pets.This is by far the most expensive vacuum we've ever had. There are definitely lower priced options that will do the job. Just not as good as this.Maneuverability -This is a very robust vacuum. It pivots surprisingly well for its size. You really can work around corners and furniture easily.The head on this vacuum is thin enough to reach beneath the furniture. It vacuums right up to the baseboard in either direction. I'm happy with it.Ease of use -The cord is adequate in length.The dust collection compartment is easy to empty. Our 12 year old is proficient with all of the functions. After all, it really is his vacuum.The lift away is pretty simple to do.The light on the head is bright enough to see in the darker corners and behind furniture. I like the light quite a bit.The crevice tool and that other thing that we use on the furniture are easily installed and removed. They both work well.Suction power-Possibly the most important aspect of my opinion on this. I'm impressed. I can tell you that your carpet is dirtier than you likely think it is. Our son vacuums upstairs every other day with the exception of the master bedroom. I do that one myself.This thing gets dust out of the carpet when the carpet looks clean. It's really remarkable.In summary -25 years ago I never would have believed that I'm on the Internet reviewing a vacuum cleaner. I'm well within the clutches of adulthood though and this is what it's come to. Seriously though, I'm pleased with this purchase. It was an expensive item for us. We had a lower priced shark before this. It still works and has been a good one. Hopefully this one will have the same longevity. Only time will tell.If you're looking to take your vacuum game up a level I would recommend this one. We do really like it.After owing Dysons for years I was a little hesitant to make this purchase but after lots of good reviews I bought it and LOVE it! Suction is amazing. Now how long it keeps this suction will be a longer term assessment. But this looks good. Love the slim profile so goes under my cabinet overhang in kitchen and bathrooms. Love the lights ( didn’t think that was a big deal until having them!), the swivel tilt really makes it easy to move around things. The lift off is amazing. While vacuuming easy to lift off with one hand and run vacuum under furniture. Having all the controls on handle is convenient. And clearly marked levers so you know what to press to release. Honestly can’t recommend this enough.
