The suction is fine, the brush USED TO WORK fine, and the vacuum has a built-in propulsion system, so it pulls the unit forward to ease in pushing it across thick carpet. It's a lot quieter than the Hoover vacuum it had replaced. The hose is very short, though, so despite a lot of pictures of these Shark vacuums showing a long hose that is easily extended, that is not the case. It just barely stretches any further than the way it appears at rest when the hose attachment is connected and upright on the vacuum. It's not a huge deal because the wand is long enough to reach our 9ft ceilings, but if you have anything much higher, you will be pulling the vacuum and knocking it over, or you'll have to detach the canister assembly and hold it while using the wand with the other hand. As long as your arms don't fatigue easily from being held aloft, using only one to hold the wand while the other is holding the canister, you might be ok. The unit is a bit top heavy, which might feel awkward for some--my wife included, but I quickly adapter and got used to it. The LED lighting on the base is very bright, and easily illuminates any dark corners for ease of use. Now for the worst part:We just purchased the vacuum along with the Asurion protection plan in November of 2020. As of mid-July, I noticed that the vacuum wasn't picking up debris from the carpet. I tried a few more passes, giving the vac more chances as any lazy person would do, before simply picking up the bits of paper and lint by hand. I then tried going across my hardwood laminate flooring, to see if maybe the vacuum was losing suction or something. I didn't hear the telltale scrubbing noise, and then I realized the brush wasn't turning. Keep in mind, the vacuum has only been in my possession for 7 months, and we haven't used it very much in that time, though I keep the canister clean, and I've taken the thing apart to thoroughly rinse it and wash out the foam filter, so it definitely hasn't failed due to neglect or dirt buildup. I checked the very thin belt that drives the brush, and it was still flexible, supple, not overly loose. It looked like a brand new belt, with not a speck of dirt on it. I detached the hose, the wand, the canister, and put everything back together, but still nothing. The hose attachment still has suction and makes the usual vacuum noise, so it's only the brush motor assembly that's failed. I took the vacuum apart and checked the connections going into the main board, and to the motor. The unit is getting power all the way to the motor, so the motor is definitely dead. It doesn't have a burnt smell, so that's not the issue--there is some other internal failure that's caused it to not turn anymore.I reached out to Asurion through the Amazon website, and it provided me a message saying that I was still within the manufacturer's warranty, so contact them, which I did. It was too late at night, and after getting the model number, serial number, and number stamped on the side of the power cord prong (?) the Shark Ninja rep told me I'd need to call back earlier in the day to do a video call with them, so they could discuss warranty options. He told me that their warranty only covers the blower motor (suction), not the brush motor, so I'd need to go through Asurion (which already directed me to Shark Ninja). So I'm, being sent in circles because the part that failed isn't covered by Shark Ninja (it's their vacuum), and I guess it's too soon for Asurion, leaving me in the time-valley of despair. Because Shark Ninja had already told me they won't cover the brush motor assembly, I went out to a brick and mortar store, and bought another vacuum cleaner, anticipating the worst--$200 for the vacuum and however much for the Asurion warranty being a waste of money.I still contacted Shark Ninja again today, and did the video call, wherein the young lady had me disconnect and reconnect the wand, hose, and canister, as well as show her the roller brush status light (which is off, since the brush isn't turning). All that to then offer to SELL ME a replacement brush assembly. I suppose I was expected to be thrilled that I was offered the part at 50% off the regular $89.99 price, and they'd waive the shipping (yay). I explained to her that it didn't seem worth it b/c the vacuum was still a fairly recent purchase, plus I had already bought the Asurion warranty, so it didn't make sense to then have to buy a replacement part, and then it could still fail in the future. She again offered me to buy the part, after providing the canned empathy statements (I know it's part of the job). I politely declined, and asked if they'd send an email or anything so I could have documentation that they could only offer to sell me another part for my vacuum. They offer no such records, but she said if I called again (why would I want to call again??) then they'd have a record of my previous interaction, so I'm left to take them at their word. This was not a good experience, and ultimately I've spent nearly $400 total between two vacuums just to have one that works. Before getting the Shark Ninja, I had never spent more than maybe 70 bux on a vacuum, and all the cheap ones lasted years before gradually failing. The previous homeowner where we currently live even left one of her old cheap vacuums, and it was still working fine, 6 years after we moved in, and I only threw it out because it didn't want to stand up on its own anymore. There's no telling how old our hand-me-down vacuum actually was, but it outlasted the Shark vacuum by far.The attached pics show the shark vacuum, and the video is intended to illustrate that while the vacuum turns on, the brush does not turn at all. The brush indicator light does not turn on, so the vacuum knows that the brush is not turning. I feel like spending more has gotten me less, and I regret the purchase.PS - we don't have any pets, and have never had any animals in our house, so the vacuum has never been overstressed from picking up any pet hair/fur/feathers, etc.
