very brief review
4 Stars
very brief review
very small, minimalistic, looks nice as if its an apple product.with that naturally, battery and the canister are very limited and small, even compared to dyson's smallest vacuum.first time owning the stand with auto empty, now i feel like i cant buy any cordless vacuum without that setup.now to the main cons.1) the light feature is below one star. why is it even there? shark spent more resources yet the execution of this feature is beyond terrible.2) lack of the extra heads. just wanted at least one smaller motor head for beds and sofas.overall it would've been 5 stars no question if the lightning feature was at least adequate. hence it gets low 4 stars.

Style: Auto-Empty SystemVerified Purchase
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!

My husband does all the vacuuming in our home and when he wanted this for his birthday, I thought he was nuts. I've had other rechargeable small vacuum cleaners and none of them had any suction at all. They might pick up dust and that's about it - anything heavier than a feather, forget it. This vacuum is small, easy to handle, and has suction power as good as our full-sized electric Dysons and Sharks. The charge doesn't last long due to the suction power, so he vacuums just one room at a time. It's lightweight enough that even I can use it for small jobs (I'm disabled and not able to push a full-sized vacuum.) My husband gets a big kick out of watching it suck the accumulated debris into the disposal receptacle when he puts it on the charger. We're very happy with this purchase. Not sure how long it will last but hoping it's durable and will keep its effectiveness for a few years.

Just think about how many vacuum cleaner designs you've seen over a lifetime! Of all the many variations I've seen, this one is superior in every way. Lightweight, cordless, and high suction. It automatically empties dirt into base unit when docked. Lights up cleaning area. Compact and slim enough to fully reach under low-slung furniture. Handle detaches for providing suction cleaning to small areas and furniture. Great for getting up dog hair. Long battery life.
Overall, a well designed product. If Hoover had been able to come up with this design 70 years ago, everybody would have had a lot easier time cleaning!

The Shark IW3511 is a powerful and versatile vacuum cleaner that offers impressive suction power and convenient features. Its sleek design makes it easy to maneuver around furniture and tight spaces, while its large dust bin capacity ensures fewer interruptions during cleaning sessions. The various attachments provided allow for thorough cleaning of different surfaces, from carpets to hardwood floors. Overall, the Shark IW3511 is a reliable and efficient cleaning companion for any household, but the most amazing thing is that my hair doesn’t get wrapped around the brushes. I highly recommend buying the one with the automatic dust bin. Crazy, but this vacuum has changed my life!

Loved the idea and what was advertised. Execution is not there. This is the first Shark product I have ever had a problem with. I have quite a few shark/ninja products in my house.

Vacuum started having what appeared to be battery issues a few months in. With a fully charged battery I would start vacuuming, after about 5 minutes or so battery would flash like it is dead. Turn unit off, wait 10 seconds or so, turn unit back on, battery is full. Use unit for 5 minutes and Repeat the process until room vacuumed.

Called warranty, they said battery, couldn’t send battery so they sent me another unit. In the midst of all of this I purchased a corded stick vacuum (also shark). Got the second unit from warranty but no return label to send first unit back. Took three more phone calls to warranty to find out they didn’t want the first unit back. I was kind of happy as the motor was bad in the first unit. Not the battery. So now I had 2 good batteries. Great for me as the batteries don’t last as long as advertised.

The Second unit I got from warranty I got to use less than 10 times before it just started shutting it self off. Another call to warranty. That unit is bad. Sounds like motor again.

Can’t get this model anymore. So now they are sending something completely different. Not anything like this system. Just a cordless stick vacuum. It will be a month before that arrives.

Thankfully the corded shark I bought is still working with no issues. So I can keep my floors clean throughout this mess. If it wasn’t for sharks warranty and good customer service I don’t know I would buy another product from them.
