From The Manufacturer

The Shark Flex is a powerful corded ultra-light vacuum expertly engineered to adapt to your life and all of your cleaning needs. Featuring Duo Clean Technology, which was invented for cleaning fine dust and large debris on carpets and floors. The dual brush roll system includes a bristle brush to deep clean carpets, and an additional soft brush roll to pull in larger particles and directly engage floors for a polished look. Multiplex Technology provides flexible reach to get under beds, couches, and tables, and folds over for compact, freestanding storage. Designed for pets and allergens. Anti-Allergen Complete Seal Technology captures and traps 99.9% of dust and allergens inside the vacuum - including many pollen, plant spores, pet allergens and other particles - down to 1 micron. Accessories remove pet hair and dander from furniture and upholstery. Active-Glide Technology provides a smooth ride over thresholds and across bare floors for effortless maneuverability. Noise Reduction Technology makes vacuuming a quieter experience on carpets and bare floors. Weighing under 10 pounds, this lightweight vacuum has a removable dust cup for easy emptying, a brush roll garage for quick and easy access from the top of the vacuum and never loses power with a generous 30-ft power cord. Not only is it great on floors, this vacuum converts to a handheld to easily clean stairs, furniture, and other above-floor surfaces. Its slim design is perfect for reaching high up and in between narrow spaces using the quick-release foot pedal to separate the floor nozzle. Easily spot hidden dirt with bright LED lights located on the nozzle.

This vacuum has HEPA filtration so folks with allergies can use this. In Flex mode, it will help the vacuum go under furniture without you having to kneel down or bending over.

The MultiFLEX wand’s design is so ingenious, you’ll wonder why nobody ever thought of it sooner. By pressing a small button on the back of the wand, you can unlock the hinge and push the handle forward, so you can get the flexible reach you need to clean under all your furniture. This time-saving feature means you don’t have to stack and move your dining room chairs or scoot your sofa. MultiFLEX also comes in handy when it’s time to put the vacuum cleaner away at the end of the day. Its ability to fold frontward to 180 degrees cuts its 49-inch height almost in half, so you can store it in the smallest of closets.

What experts didn't like

The downside though to the lightweight, top-heavy design would be the small dirt cup. And since it is top-heavy, your arms may feel the strain if you use this for an extended period. The narrow head is only 9” wide and the lack of storage for tools.

SharkFLEX DuoClean vacuums also cost slightly more than Shark Rocket DuoClean vacuums.

If you have a larger home with mostly carpets, especially thicker ones then it wouldn’t make an ideal choice.

An Overview On Shark Vacuums

Finding the perfect vacuum cleaner for your home can be easier said than done. But, if you’ve already decided on the brand you’d like, you’re halfway there. Shark is a leading name in the household appliance industry. So if you’ve selected this as the brand you’d like to bring into your house to help keep things tidy, you’ve chosen well. However, there are many different types of vacuums under the Shark name, so now it’s time to compare a few to find out which one really is the best one for you.

For example, the Shark TruePet Canister Upright Vacuum was voted as the best overall when examining the brand’s top products. However, if you don’t have pets and therefore a ton of hair to pick up all over the house, this may not be the option for you.

In that case, you may want to go for the best value, which likely means you’ll walk away with the Navigator LiftAway Vacuum. This model is easy to maneuver and works on a variety of surfaces, including hardwoods, carpet and more.

There’s much to be considered when shopping for a vacuum, but the good news is that Shark has a lot to offer. So, whatever your needs may be, there’s bound to be a machine that will get the job done — a highly rated machine, at that.

Stick around and we’ll get into the nitty-gritty (pun intended!) of what makes each of the four top-rated Shark vacuums so great. In the process, you’ll discover exactly what your home needs from a vacuum cleaner in terms of pick-up power, maneuverability, storage and more. Then, you’ll be well on your way to maintaining a tidy space once and for all.

Here’s to finding the Shark vacuum that will work for you. After all, when it comes to keeping your home clean, only the best will do!

The Shark Vacuum Buying Guide

  • While it may not be the obvious thing to consider when purchasing a vacuum cleaner, how much the machine weighs should definitely play a role in your decision. If you’re going to be lifting this thing up and down stairs to clean multiple levels in your home, you’re likely going to want something that’s lightweight. In that case, look to the Rocket DuoClean or the Rocket Complete Ultra-Light models to make things easier on yourself.
  • Be sure to think about where you’ll be storing your vacuum when it’s not in use. The bigger and bulkier the machine, the larger the closet or space you’ll need to make sure it’s not in the way until you need it. If you’ve got a large laundry room or closet to store your machine in, the TruePet Canister option could work great for big messes in your home. If you’re in a smaller space, however, a large vacuum might feel like clutter if not properly put away. So be sure you know exactly where your vacuum will “live” in your home before making a purchase.
  • While you’re definitely more focused on how a vacuum will keep your space clean, you’ll also have to think about what is required to keep your vacuum clean and operating at its best. A canister vacuum, such as the Navigator LiftAway model, makes it easy to tell when it’s time to empty the canister so that there’s plenty of space for sucking up debris and more. You’ll never have to guess when it’s time to empty what your vacuum’s collected so far, as you might with bag vacuum models.
  • You’ll definitely want to consider the type of suction power you need for your home. Do you have carpets? Pets? Kids? All of this will come into play when choosing the best machine to keep things clean. The TruePet Canister Upright and Navigator LiftAway models are great for heavy-duty types of cleanup. Meanwhile, if you’ve got a smaller apartment with tiled floors, a heavy duty vacuum with tons of suction power may not be necessary to keep your space in order. The types of messes you clean up most often will dictate your needs here.
  • The surfaces your vacuum will encounter also matter. Will it be transitioning from tile to carpet as you move from room to room? If so, you’re going to want something that will easily adjust to the different needs for picking up on a smooth surface versus one that can trap dust and debris. Models such as the Navigator LiftAway and the Rocket DuoClean are great if you’ve got multiple types of flooring throughout your home. They’re made to transition from room to room and offer versatility, attachments and more to suit your needs.
