Shark Detect Clean & Empty Auto-Empty System - Lightweight Cordless Vacuum Cleaner with HEPA Filter, Portable Handheld Attachment, Crevice Tool, Ideal Stick Vacuum for Pet Hair, White, IW3511

Okay, so we have big needs when it comes to a vacuum. We have two large dogs, three cats (two that are long hair) and a toddler (plus me and her mom) all living in a 1000sq ft single floor home. We MUST vacuum daily. We have a robot vacuum that does most of the heavy lifting when it comes to daily vacuuming, but it of course doesn't get crevices, furniture, doesn't do well in corners, under cabinets, etc. So, we had a corded Bissell to take care of big messes, and what the robot couldnt get. We went through three of these corded Bissell over the course of two years. THREE. All failed after 8-10 months. Plus, being corded, it really didn't get used as much as it should. Who wants to dole out a 25 ft cord to vacuum one piece of furniture? Or do clean up the dirt the dogs just tracked in? Yeah, nobody.So, we decided to try out a cordless. We settled on this shark here. We loved the fact it has auto empty feature. It may sound gimmicky, but let me tell you, it's awesome! My wife especially used to hate emptying the bin on our old corded vac. Anyone with pets knows that when you let pet hair/dander sit in a vacuum for a week or two, it really starts to stink. So, the air coming out of the vacuum would stink, and emptying the bin in the trash would spread stink everywhere, along with dust and dander. The auto empty feature of this shark is awesome. Put it on the dock, and poof, everything's gone and vacuum is ready to go for it's next use. The amount of filters in the vacuum and the auto empty base ensures absolutely no smells or dust escapes. It is totally worth it and one of the main things we love about this vacuum.The vacuum itself is also extremely good. We were worried about run time and suction power, being cordless, but on auto mode we have enough battery to vacuum the whole 1000sq ft floor, plus do our big sectional couch. You'll definitely use the battery quicker when the roller brush and suction are on high, but it seems to have plenty of battery for us. If you have a large home or lots of rugs/furniture, you may run through the battery quite quickly. Suction on this shark is great as well. It is as good if not better than our old corded Bissell. The roller brush truly is anti-tangle as well. Our dogs are starting their spring shed right now and even with all the hair we have sucked up, the roller brush is completely free of hair. This is the first truly tangle free roller head we've ever had on a vacuum.The only cons to this vacuum definitely aren't deal breakers, more so just quirks. In detect mode, the vacuum is a bit slow detecting. It's slow detecting amount of dirt, it's slow detecting when it's against an edge, and it's slow when its detecting carpet or furniture. When I say slow, I don't mean it takes forever, but if you're vacuuming quickly, you can easily run across a door mat and the vacuum will just be kicking up the suction as you're leaving the mat. If you vacuum a little slower on carpets or against walls, it easily detects them and will do it's thing, but if you're a quick vacuum-er, you'll find the vacuum confused and varying the suction and roller speed constantly as it's trying to catch up to what you're doing.Also, another quirk, the wheels are smooth hard plastic. Our laminate floors are very slippery against smooth hard plastic. So, again if you're vacuuming quickly, and you try to turn the vacuum, it'll have a tendency to want to slide around. Not overly annoying, and if you just slow down a bit it's not noticable, but some rubber coated wheels (like our old Bissell had) would go a long way to fixing this.Overall, this is a great vacuum. Battery life is on par for a cordless vacuum and is plenty for a smaller home, suction is great, auto empty dock is a must have. We find ourselves using this vacuum way more than our old corded model because it's so easy to use. And, for the first few weeks, the auto empty is so fun to watch!EDIT 5/8/2025This vacuum is a little over a year old. A year of moderate to heavy use, it's still going strong! The roller head STILL has not had ANY tangles, very impressed with that. Battery life has taken a bit of a hit, we can still vacuum the floors throughout the whole house but sometimes dont have enough battery to do the couches. Pretty on par for any rechargeable device though.10/10 would still recommend.

I bought this product "Like New" from a seller that has many poor reviews. I was skeptical on what the condition of the product would be in, but as I unboxed it, I was super satisfied. For it being less than half the price of a new unit, I got what appears to be a new unit without the original box. Everything was packaged in its original plastics and had its original stickers. The roller, canister, the bin, and filters had ZERO debris of it ever being used. Like I said, the only thing it didn't come with was the box and manual. It did come with a piece of paper with a qr code to the online manual. As for the product itself, I dont know how long it will last. I include a picture of where the handle attaches to the stick that seems to be a little wonky and have some slight play to it where I can see this becoming an issue down the road. The vacuum is light and easy to push around. If you dont ram it into objects or walls, it might last for a while. My home is around 700sq ft and I was able to vacuum it and go over half of it a second time before dying in auto detection mode. The 1st of 4 lights on the battery indicator went off quickly, but when the last light went out indicating me to charge it, I got about another 5 minutes before it completely shut off. When I put it on the docking station, the canister was packed pretty tight, but the auto empty sucked the canister completely empty in a blink of an eye. I read reviews that over time, the auto empty looses power and doesn't do a good job, but we will see. Like I said, I got this for 65% off the original price, so if it lasts even 2 years I'll consider it money we'll spent.

I wanted a stick vacuum and after my sister got the Shark self cleaning vacuum I began researching which one I wanted. This one went on sale and I am so happy I purchased it. (I have a pet, she doesn’t)I only had one issue, the suction was almost too good. I vacuumed my entire house and was surprised how much stuff it got considering I was replacing a Dyson. I didn’t realize when it emptied itself it clogged down near the docking canister. After a few more uses I couldn’t figure out why it wasn’t emptying or what was going on and when I figured it out, it was super easy to empty and clean. It has worked perfectly before and since this little setback.I have hardwood, tile, carpet and stairs for reference. It easily transitions from surface to surface making my life so much easier.Love this vacuum, so glad I got it.
