Don’t miss:

Max suction power

Shark F80 vacuum has cordless and powerful suction for dirt, pet hairs, debris, and dusty areas. It has two suction power modes such as Ion boost mode and Ion power mode. You can adjust the suction power of the vacuum according to your requirements by changing its mode.

In addition to that, the ION boost mode offers 38 CFM and ION power mode delivers 24 CFM suction power. These powers are great for cleaning everyday dirt.

Adjustable power

The best thing about the Shark ION F80 MultiFlex vacuum is that you can adjust its power according to your targeted areas. It offers two modes Ion power and boost mode. Both modes offered different suction power. For example, if you set the Ion power mode it offers you less suction power as compared to Ion boost power.

Noise level

Shark F80 is good to stick vacuum in terms of noise because it has a 69-dB noise level. You can use this quietest vacuum in the home, office and other places as well. It is very easy to clean and maintain this cordless vacuum. Furthermore, it cleans the hard floors, picks pet hairs, and clean dirt from the carpets quietly.


Shark ION F80 lightweight cordless stick vacuum is a bagless vacuum, which makes it easy to clean, maintains, and use. The bagless vacuums used a filtration system to collect the debris, dirt and other tiny particles. It picks all debris or dirt into the chamber or dirt cup.

Dustbin capacity

Bagless Shark lightweight stick vacuum has a dustbin that keeps the dirt, debris, and other particles in it. The capacity of its dustbin is 320 ml.

However, the capacity of this vacuum is less as compared to other models (such as Shark Rocket HV382). Therefore, it is hectic work to clean the bin after cleaning the rooms repeatedly. That is the reason; it is suitable for cleaning small areas such as a bedroom or a small office room, etc.

Power source


Shark ION F80 MultiFlex is a cordless vacuum that has featured with MultiFlex DuoClean and handy vacuum. This cordless vacuum has two brush rolls and on powerhead that is inverted for collecting large debris and fine dust on the hard floor and carpets.


Shark ION F80 MultiFlex cordless stick vacuum uses the battery for power. Therefore, there is no need to worry about installing any kind of cables and outlets. It has a powerful lithium-ion type 25.2V battery, which produces 300 watts. The best thing about this battery is that it is removable and rechargeable.


Shark F80 has two powerful Lithium-ion batteries that continually work for more than 80 minutes. This is totally cordless and Ion power mode runtime. This runtime has measured when it works as a hand vacuum.

Charging time

Shark ION F80 vacuum has a rechargeable battery and it takes about 210 minutes for a full charge. You can switch the battery according to your requirements. You can remove the battery and charge it while storing it in the storage place.

Hose & stick length

This is where the Shark F80 truly stands apart from its competition. It boasts MultiFlex technology that allows you to bend the stick as per your required to do the cleaning under the furniture without bending your back.

The stick of this vacuum starts working like a hose and bends as much as you need to get to those hard-to-reach places. The length of this stick-hose is 3.85 feet that are ideal for you to work without bending your back or putting pressure on it.

Motorized brushroll

One of the best features of the F80 vacuum from Shark is its brushroll which the company has motorized. This is a particular reason why the cleaner is so effective on hard floors. Apart from that, there are two different types of these brushrolls and you can use each of them based on whether you are vacuuming hard or carpeted floor.

The brushroll is so effective that it tends to move the cleaner forward on the carpet if you use high suction power. Therefore, when cleaning the carpeted surface you need to use lower suction power for better cleaning.

There are two different power modes: one of them is ION Power and the other one is ION Boost. ION Power mode is for your normal-day cleaning and on hard floors while ION Boost is for high powered cleaning and is excellent for high-traffic areas of your home as well as the carpeted regions.


There are two different types of brush rolls that Shark has used in the F80. One of them is the soft brush while the other one is bristled and is pretty stiff. You can use the stiff one on the carpets and use the softer one on the hard floors.

The best part? You don’t have to do anything manually. Just choose the setting and the machine will automatically select the brush type as per need. Therefore, you can do safe cleaning on hard and sensitive floors and efficient cleaning on carpeted ones.

Cleaning path

Despite its compact size, the cleaner is able to provide you with a cleaning path of 8.6-inch. This is good enough for you to work in small to medium-sized spaces. For this reason, if you have a large home or most of the area in your home has no furniture then it will take a good period of time to complete your cleaning job with Shark F80.


There are two different types of filtration systems in this cleaner. It uses washable filers for both these systems. These filters are made of felt and foam and they can clean the air that enters and leaves the vacuum.

Shark highly recommends that you regularly clean these filters so that the vacuum’s functionality remains at the top level without deteriorating its suction power over time. However, you need to bear in mind that if you are prone to seasonal allergies then you have to take care of yourself because these filters are not HEPA certified.


Shark ION F80 tools

Shark also provides you with some accessories and tools to work with while using this vacuum. They are not plenty but still good enough to keep everything simple and convenient for you. But the good thing is that you can purchase a host of different items as add-ons for your Shark F80 vacuum cleaner. Your purchase will include a crevice tool, two brushrolls, a powerhead, two rechargeable batteries, a charging dock with charging cable along with an upholstery nozzle.


Pet hair

The Shark F80 stick vacuum is good in a lot of areas but cleaning pet hair is not one of them. There are better options in the market for you to explore this vacuum. If you don’t own many pets then this cleaner might work for you but you will have to keep cleaning its brushrolls with flea combs to maintaining effective cleaning.

However, if you have more pets then furniture at your home, then you should pass this vacuum and go for a more specialized model. For its below-average performance to get rid of pet hair, we are giving it 3 out of 5 stars.


We were pretty amazed by the performance of this vacuum on carpeted floors especially the short pile ones. But don’t go for this cleaner if you have long pile carpets because its brushrolls are not that effective on these carpet types. Switching from hard floor to carpet mode is pretty simple and neat and you will thoroughly enjoy your cleaning from one room to another.

Hard floor

Hard floor is the area where Shark F80 specializes and for this reason, it gets the highest rating here too. If most of the rooms in your home are hard then you definitely need to have Shark ION F80 MultiFlex as your cleaning partner.

Its excellent suction power of 38 CFM can take care of all types of dust and debris on your floors and it will also do it under your furniture with the same level of efficacy. Even in a hand vacuum, this cleaner will clear out all the dirt from your walls, ceiling, and curtains without you batting an eye.


Apart from all the features that this cleaner has, it also comes with a long warranty. Shark provides a 5-year limited lifetime warranty on the vacuum and also offers a 2-year warranty on the batteries that are included in your purchase.

Shark is highly regarded for its exceptional after-sale and customer service and it doesn’t break the trend with the ION F80 stick vacuum. The Shark will cover all parts and labor concerns under this warranty for your peace of mind.

Special features

There are some special features of the Shark ION F80 vacuum cleaner that set it apart from others in the same category. One of them is the DuoClean technology that allows you to run this vacuum easily on different types of surfaces including hard floors and carpets.

As we have mentioned above, its motorized brushroll allows you to switch from carpet cleaning to hard floor cleaning by just clicking a switch. There is no need for manual adjustments and it’s enough to facilitate you in cleaning across different types of floors.

Moreover, there is this MultiFlex feature as well that enables you to do the cleaning under your furniture without pressing on your lower back. So if you have to deal with those achy lower back pains then this vacuum is the best option for you to use. Additionally, the easy conversion switch ensures that you can switch from regular mode to boost cleaning with just a flick of the switch and move around the house effortlessly.

And then there is that easy conversion facility to hand vacuum. With Shark F80 you can not only clear the debris and dust on the floors but can also do it on ceilings, walls table surfaces and curtains too. It is a complete all-rounder that can handle all types of mess with excellent suction power too.

Final thoughts

To sum it all up, the cordless stick vacuum F80 from Shark is one of kind because it is good on both hard and carpeted floors. It delivers exceptional run time with the two lithium batteries it has and can work around the furniture with high efficiency. This vacuum offers good suction power and can handle all types of debris and dust.

However, with that being said this vacuum is not that efficient with pet hair. You need to use a flea comb to get rid of the hair from the brushroll and it also drops the debris when you turn it off. This can result in a mess if you are not aware of it at first hand. Apart from that the F80 also tends to overheat from time to time.

Nevertheless, you can conclude from this Shark ION F80 review that the vacuum is pretty handy for different types of floors and can take care of most types of mess. It has a good runtime can get the job done with maximum convenience.
