It’s time to review the Shark F80 Multiflex cordless vacuum, which depending on how you look at it, has the longest battery life of any cordless vacuum we know of. The new Shark F80 is basically the upgraded version of the Shark IONFlex 2x which we have reviewed in the past. The F80 has many of the same features as the IONFlex, including the DuoClean technology, LED lights on the nozzle, the multiflex feature which is a flexible wand activated by a button to vacuum under furniture without bending over, it also acts as a way to conveniently store the vacuum when not in use.
Attachment packages can vary but mine came with a crevice tool, an upholstery tool, a car-detailing crevice tool/ dusting brush, a charging dock, and two ion battery packs. It has a low and a high power with a high power being on a 1-minute timer, which is new. You can also flip a switch to change from carpet to hard floors which changes the suction and the brush roll speed.
Let’s get into the pros. I love the DuoClean technology, which is an innovative cleaner head design which incorporates a soft roller which makes it amazing for hard floors as well as a standard brush roll for carpet agitation. With DioClean to touch it is to vacuum it, and it’s why we use DuoCleans with our cleaning business. Quite simply, DuoCleans can pick up things other vacuums just can’t. This is mostly evident with large debris on both hard floors and carpets but its performance with fine dust is also well above average for vacuums of any type. And it does all this while retaining one of the best seals on hard floors and carpet which is evident from its top-5 performance on the crevice pickup test.
It’s also a magnet for pet hair on hard floors and carpet but it’s agitation is pretty good for cordless vacuum doing quite well with fine debris on carpet. All of these tests were done in both low and high power and I didn’t find any instance where the high power was strictly needed since the DuoClean nozzle relies less on air flow than other cordless vacuums but rather than on the mechanics of the floor head. All that to say that its low power was quite enough power.
Another big pro is its battery life and this is also where the biggest change from the previous IONFlex cordless vacuums comes in. So despite the exact same battery being used with the IONFlex, Shark has increased the battery life by adjusting the power of each setting for the F80.
For example, Shark has reduced its power on low power to 24 CFM at the wand which now matches the Dyson v10 on its low power setting giving it 43 minutes and 32 seconds per battery on suction only attachments for a whopping 87 minutes total or 2834 per battery, 57 minutes total, on low power with the cleaner head attached, and 1331 per battery, or 27 minutes total on high power with the cleaner head attached, which is pretty good even before you factor in the extra battery. But as you can see it also makes the Shark F80 the best cordless vacuum for battery life that we have tested yet.
I should also mention that its power on high power is pretty significant, reaching 84 inches of suction and 38 CFM of airflow at the wand, which is above average for cordless vacuums on both counts. I initially thought the multiflex feature was just a gimmick but I do find it’s intuitive and helpful for getting under beds and other furniture and I do actually use it.
The bin size is kind of a pro in that it’s just a little above average at 2 and 3/4 cups. This is compared to the Dyson V8 at 2.5 cups which I consider the average amount. I liked how springing the bin release was, but like other cordless vacuums, you do occasionally have to fish out stuck debris but not quite as much as other cordless vacuums.
So let’s move on to the cons. It’s pretty minor, but although the weight of the handheld unit is basically the exact same as the Dyson V8, which I consider to be light, its weight distribution is not quite as good and it’s a little more tiring on the arm in handheld mode, at least with a wand attached. And while I consider it very easy and lightweight on hard floors, on carpet, the DuoClean roller does have a tendency to act like a self-propelled vacuum which takes additional energy to keep pulling it back. Though I did notice that this effect almost completely goes away on its low power setting on carpet, which is a good change from the previous version.
The last con is that it’s the only Shark vacuum I know of, besides the other IONFlex and rocket models, that does not have a HEPA filter. If you want a Shark cordless with a sealed system and a HEPA filter, you’ll need to upgrade to the new Shark P50, which we have reviewed and really liked.
So the bottom line is this: the Shark F80 cordless vacuum is better than any non-DuoClean cordless vacuum you can get in terms of its pickup ability and it’s also the best you can get in terms of battery life for a cordless vacuum that being said, it’s not all that different from the Shark IONFlex 2x which also comes with two batteries.
