I generally warn folks to stay away from Shark in general, as they do not put a whole lot of emphasis on the longevity of their designs. Most of them, although they have nice features and work well out of the box, have especially dirty bin and filter setups and lack overall build quality. Dyson and Shark are compared directly quite frequently, but Dyson by far offers the better products with superior customer service, in my personal experience at least. I think the price Shark asks for the Stratos cordless is a lot of money for the quality of the machine. I like Vacuum Wars, but his videos do not always take that stuff into account, and I see it in the wild quite frequently from working on all types of vacuum cleaners. It is above your budget, but if you did not see, Dyson is offering a sale at $649 on their V15 Absolute package , which comes with a few fancy attachments, both the universal head for hard floors and carpet and the dedicated hard floor head with the laser, the "Detect" dirt sensor, the powered head you would want for stairs, built-in crevice tool and dusting brush, and so forth. For a unit that they typically sell for $799, the current sale price is actually a solid deal. I am guessing that it is discounted because Dyson is about to roll out a new model, the Gen5 Detect, to dethrone the V15. Since your budget is flexible, I thought it would be worth mentioning, because it really blows the V8 out of the water in about every way. There is some saltiness against Dyson on this subreddit, but the V15 is currently one of the most powerful cordless machines on the market. Dyson designed the V15 to replace a corded machine and I have yet to see evidence that one cannot do so, and the high levels of airflow and suction back that one could. Definitely take any claims that they cannot with a grain of salt, because it likely comes from a place of personal bias. That is an ongoing problem with certain folks. Of course, there are downsides to a cordless machine such as the V15 with examples being run times (though impressive), charge times, and long-term battery life. With that said, I know many people love the convenience of a cordless stick platform vacuum cleaner. If you want something cheaper but of similar quality to a Dyson, LG offers some great deals such as the CordZero A907GMS , which also comes with a universal head, dedicated hard floor roller, and miniature motorized tool for stairs. A few benefits that it has over a Dyson are that it comes with a dual charging stand, it has a cyclone pack that can be washed with the filters, and it has an extender wand. Basically anything from LG would work. They make Kompressor models that are more powerful than the regular models and have a lever that you press to compact the debris in the bin, so definitely search around and find an attachment package and price that is suited for you if you are interested. The main differences between all the models they sell in the CordZero line are the attachments, the amount of batteries, and whether it is a Kompressor model or not. The LGs are of good quality, so no worries there. This is just cordless vacuum cleaners, since that is in what you seem to be interested. I could also list a few corded machines if that would be helpful, because there are benefits to those. More on reddit.com

I don't recommend any Shark products, they work well when they are brand new but when they break most parts aren't covered by their warranty and they are unrepairable. For a mix of carpet and hard floors you'll want a vacuum with a powered brushroll that can turn off. Manual carpet height adjustment is better. For pet hair I have found all vacuums get some hair wrap so the best strategy is to get a brushroll that is easy to clean. You may want to save your Kohl's gift card for something else as some of their vacuums aren't competitively priced. There are a few Kenmores worth looking into but they are more expensive at Kohls than they are on Amazon, but I know that's because there's Kohl's Cash bennies. Kenmore Elite BU1018 $399 is a very capable vacuum cleaner. Hepa bags and hepa filter for great filtration. It has a strong brushroll with shutoff. Downsides are it has a short hose and it is heavy to lift. The identical Kenmore BU1017 is only $249 on Amazon. Kenmore Intuition BU4021 $199 is a compact upright vacuum. It has swivel steering, liftaway mode, hepa bags, and a hepa filter. Downsides are smaller bags, a short hose, and no carpet height adjustment. The Kenmore Intuition BU4050 $189 on Amazon comes with 2 more bags and an anti-tangle brushroll. Sebo Dart $549 is the BIFL option that will last 15-20 years. It comes with a 10-year warranty. The build quality is better and it is quieter than most bagless upright vacuums. The brushroll pops out without any screws for easy cleaning. Downsides are a short hose and it only comes with 2 tools when it should be 3. More on reddit.com

I don't think anybody in this sub is going to recommend you buy a Shark stick so you're probably not going to get the answer you're looking for. Try searching the sub for stick vacuums, you may find something better. More on reddit.com
