I actually was in the market for a new vacuum as there were parts breaking on my Bissell 2999. (Dust buildup inside the motor housing leading to bearing whine, brush roller wear that required modification to prevent additional damage, as well as handle damage that prevented the vacuum handle from staying locked in place and later being unable to be removed as it got jammed slightly at an angle.) Moving on, this is actually a step up, despite having got it at a substantially lower price (99 dollars verse the original Bissell 2999 price being around 200 dollars.) I wanted something that people praised for higher reliability, and this advertised a limited 5 year warranty. I got it, because 99 for a well reviewed vacuum was excellent in idea. I then looked at reviews all over the internet only to find out more and more that the Shark NV360 was way better than expected. My only caveats to date are that it has a smaller agitator head, and that it doesn't come with a agitator attachment, you'd need to get the Pro version NV356E to get the agitator attachment. It does come with a smaller crevasse tool and a very functional upholstery tool that also worked very very well on the stairs. Suction on this vacuum is amazing. Especially compared to my Bissell 2999. I have Hoover and Bissell Vacuums, and the 2999 was better than my previous vacuums, but oddly not better than this current one from Shark, the NV360 just to keep things clear. The hose diameter is larger, and that typically means less pressure for most vacuums, however, that is not the case here. You really need to be careful when using the attachments as it will suck up a sock you may have got too close too and it'll all be too fast to recover from anywhere other than the dust bin. Emptying the dustbin is more involved than my Bissell and Hoover vacuums, where a single button press allows you to pull the bin from its' resting place. In the case of the Shark, you will need to undo two latches that secure the bin in place, but while I thought this would be a bigger problem it has not been. Installing the bin has been a bigger issue than removing it but the process is still really simple. The dual latch does offer the better seal though as it allows for more uniform pressure on the seal under neath and keeps the dust flowing down. It does seem that the foam prefilter would need more cleans than my Bissell 2999 required, but I found that dust released from the Bissell system would agitate my nose a touch, because allergies, while I have had zero incidents of that with the shark. (The Bissell 2999 was still the best I had before I got this NV360 for allergies I experienced, I just thought it was because it was kicking something up but dust patterns formed later in its' life showing it was some dust leakage.) Moving this around is easier than the Bissell 2999 as well, but that is partially because the base is smaller. Both were swivel style vacuums but the NV360 does better on tighter turns than the Bissell. The smaller head seems to also focus more of the dust into the dust bin. Going over areas the Bissell seamed done with, I found that there was still a ton of dirt and dust embedded into the carpet even after 8 passes with the Bissell. I only knew there was more because even though I wasn't getting anything more on the 8th pass with the Bissell, going over the same area with the NV360 showed there was still a lot of dust left in the carpet. The Bissell did get all the dog hair though and there was only dust and dirt that the shark was able to extract. (This also lead me to do a carpet clean though, as I have a Bissel carpet cleaner that I really like and I finished the job with that.) My lesson learned though is that even with a great vacuum like the Shark or my previous best Bissell, you may have to vacuum more often than every 3-4 days as that dirt just keeps getting deeper if you dont. Moving on, I am actually very impressed and absolutely can recommend this vacuum to anyone who needs something better. I absolutely can recommend it to anyone who has allergies like me as well. Best vacuum to date. Side note though, when researching vacuums, I did find that the Shark Stratos and Rotator options are more amazing when it comes to airflow and pressure as well as large objects and long hair, but they are between 200 and 300 dollars. For me this is the best option for now, especially seeing it was only 99 dollars when I got it.
