The Shark PowerDetect Speed Clean & Empty IA3241 is a mid-range model in Shark's line of cordless stick vacuums. The included dock automatically charges the vacuum and empties its dustbin between uses, so you can skip manually emptying it after every clean. The MultiFLEX wand lets you reach under furniture without bending over, and it converts to a handheld vacuum for cleaning upholstery, stairs, and other tight areas. The PowerDetect Intelligence feature automatically adjusts suction based on the floor type and amount of debris it detects, and built-in lighting helps reveal dust on hard floors. It also features a self-cleaning brushroll, HEPA filtration, and a removable battery, so you can swap in a spare to extend your cleaning time.
Our Verdict
The Shark PowerDetect Speed Clean & Empty IA3241 is a decent choice for whole-house cleaning. In ECO mode, the battery will last long enough to clean an entire home, though higher power settings for cleaning carpets or heavier messes drain it much more quickly. It does a great job lifting pet hair from carpets, but its performance drops on hard floors, and it really struggles with high-pile carpets. Since it's lightweight and cordless, you can move between rooms and floors without having to hunt for an outlet. Unfortunately, despite its HEPA filter, this vacuum doesn't do a good job filtering fine particles, so allergy sufferers may want to look elsewhere.
Sturdy, solid-feeling build.
Adeptly lifts pet hair from carpets.
Cordless design lets you clean without being tethered to an outlet.
Doesn't filter all fine particles despite having a HEPA filter.
Emptying the dustbin releases a cloud of dust into the air.
Low suction limits deep cleaning power.
The Shark PowerDetect Speed Clean & Empty IA3241 is a decent pick for a small apartment. It stores away easily, sitting compactly on its dock without needing dedicated closet space. Bare floor and carpet debris pickup are just okay, but it excels at tackling pet hair, making it a great fit if you have shedding pets. It's compact and cordless, so it's easy to maneuver in small spaces, and you don't have to worry about finding an outlet. The biggest downside is its impact on air quality; although it's equipped with a HEPA filter, it doesn't filter fine particles effectively, and you'll create a cloud of dust when you empty the bin.

The Shark PowerDetect Speed Clean & Empty IA3241 is a good option for cleaning stairs. Its light weight makes it easy to carry up and down, and since it's cordless, you don't have to deal with a cord or search for an outlet. Actual pickup performance is only okay on both bare floor treads and carpeted stairs, though it does do a great job of lifting pet hair. Air quality is the weak point here, with more dust being released than you'd want in an enclosed stairwell.

The Shark PowerDetect Speed Clean & Empty IA3241 does an adequate job of cleaning a car. It's lightweight, portable, and the included crevice tool and extension wand make it easy to reach into tight gaps around seats and consoles. The major downside is that suction is very low, so it may not be able to lift ground-in dirt from car carpets or mats. On the bright side, it'll do a solid job cleaning upholstered seats and removing pet hair with its included upholstery tool.

The Shark PowerDetect Speed Clean & Empty IA3241 does a mediocre job cleaning bare floors. It clears most large debris in open areas, but leaves some fine dust behind. It struggles more in trickier spots like corners and baseboards, leaving a noticeable amount of debris in its path. Because of its poor suction, it can't lift dirt from cracks, so it's not the best choice if you have old wood floors or tile with deep grout lines.

Struggles to pick up debris in crevices and cracks.
Leaves debris behind along baseboards and in corners.
The Shark PowerDetect Speed Clean & Empty IA3241's performance on carpets depends heavily on how shaggy your rugs are. On low-pile carpet, it performs well, picking up debris consistently across the board without any major weak points. High-pile carpet is where it falls short, leaving a noticeable amount of debris behind, especially finer particles that tend to sink deeper into thicker fibers.

The Shark PowerDetect Speed Clean & Empty IA3241 does a great job of dealing with pet hair, even on difficult-to-clean surfaces like carpet, leaving almost no hair behind after a single pass. It performs well on upholstery, which is helpful if your pets tend to leave hair behind on your sofa.

The Shark PowerDetect Speed Clean & Empty IA3241 doesn't do a good job of keeping your home's air clean and isn't the best choice for people with allergies. Despite having a HEPA filter, it isn't able to contain fine particles as you clean, and will reintroduce dust into the air. It gets even worse when it's time to empty the dock. While the dock's filter does a good job of containing dust during the automatic emptying process, the dock's own bin is bagless, so you'll eventually need to empty it by hand, and doing so releases a cloud of dust back into the room.

Differences Between Sizes And Variants
The Shark PowerDetect Speed Clean & Empty IA3241 comes in five colors: Ice Blue, Walnut, Sagewood, Harbor Slate, and Oatstone. We bought and tested the Clean & Empty IA3241 variant in Ice Blue, which comes with a self-emptying dock. You can also purchase the base model without the dock (Shark PowerDetect Speed IA1241). Here's a photo of our label.
Popular Vacuum Comparisons
The Shark PowerDetect Speed Clean & Empty IA3241 sits in the mid-range of the cordless stick vacuum market, and its main draw is convenience. Like the Shark Detect Pro IW3511 here, it comes bundled with an auto-empty dock that charges the vacuum and empties its dustbin automatically, which is rare at this price point. Combined with great pet hair pickup, this is a strong option if you have shedding pets and want to spend as little time as possible on maintenance.
That said, it falls short when it comes to raw cleaning power. Suction at the floorhead is a significant weak point, so it can't perform as well as the Shark PowerPro Flex Reveal Plus or Shark Stratos Cordless IZ862H when it comes to cracks, crevices, and high-pile carpet. Although it comes equipped with a HEPA filter, it isn't able to fully contain fine particles as you clean, reintroducing allergens into the air. If anyone in your home suffers from allergies, they'd be better served by a model like the Dyson V8 or the Shark Cordless Pro IZ562H.

The Shark PowerDetect Speed Clean & Empty IA3241 and the Shark Stratos Cordless IZ862H are both cordless stick vacuums from Shark, but the Stratos Cordless is the better overall pick. It offers better cleaning performance across the board due to its higher suction power, which enables it to lift dirt from cracks and high-pile carpets. The Stratos also keeps noticeably more dust contained in the air while you're actively cleaning, though both vacuums kick up a cloud of dust when it's time to empty them. The PowerDetect Speed's primary advantage is that it comes with a dock that empties its dustbin and keeps it charged automatically between cleaning sessions, so you'll rarely need to handle the bin yourself.
The Shark Cordless Pro IZ562H is a better overall performer than the Shark PowerDetect Speed Clean & Empty IA3241. It picks up debris more effectively on hard floors and in cracks and crevices, and keeps much more dust out of the air while you clean. The PowerDetect Speed does have a couple of things going for it: pet hair pickup is noticeably stronger, and its auto-empty dock lets you skip handling the dustbin yourself. It's also easier to maneuver thanks to its bendable wand.
The Shark PowerDetect Cordless IP1251 is the better overall performer compared to the Shark PowerDetect Speed Clean & Empty IA3241, despite sharing many of the same features. It clears more debris on hard floors, high-pile carpet, and in cracks and crevices, and it keeps far more dust out of the air while you clean, which is surprising given that both vacuums use the same filter. The PowerDetect Speed does pull ahead in a few areas: pet hair pickup on carpet is noticeably stronger, and it's lighter to carry around the house. Both models have variants that include self-emptying docks.
The Shark PowerPro Flex Reveal Plus is the stronger overall cleaner than the Shark PowerDetect Speed Clean & Empty IA3241. It delivers a more thorough clean on both hard floors and carpets, and lifts pet hair more effectively. It's also the better choice for allergy sufferers, because it does a significantly better job keeping fine particles contained as you clean. The PowerDetect Speed does have a few advantages, though. It comes with an auto-empty dock, so you won't have to handle the dustbin as often, and it's lighter, so it's easier to carry around. It's also cheaper to maintain long-term, since it doesn't require replacing filters on a schedule the way the PowerPro does.
Test Results
This vacuum does a decent job on hard floors. In Detect mode, the TurboPro Detect brushroll clears most medium and large debris in a single pass, but leaves some fine dust behind. It also struggles to fully clean along baseboards due to its floorhead's bulky design.
The Shark PowerDetect Speed really struggles on high-pile carpets, and won't clean them thoroughly. In Detect mode, you'll notice debris left behind, especially fine dust and smaller particles. It lifts larger debris more effectively. Edges are a weak spot too, with debris often left behind along walls and baseboards.
This vacuum does a good job of cleaning low-pile carpets. You'll notice a bit of debris left behind after each pass, and it doesn't fully clear corners due to its bulky floorhead.
This vacuum does an excellent job of lifting pet hair from carpets, making it a smart choice if you have shedding pets. Each pass clears almost every strand of hair, with only a very small amount left behind.
This vacuum does a good job of removing pet hair from furniture. Using Detect mode and the upholstery tool, most pet hair comes up in a single pass, but hair tends to build up in the crevices of the tool itself, so you'll need to clear it out by hand every so often. The exhaust also tends to blow loose hair around as you clean, which can leave you chasing stray strands across the furniture instead of collecting them.
The PowerDetect Speed can't lift dirt from cracks, so it's not a great fit if you have old wood floors. Its floorhead can't form a tight seal, and increasing the suction level doesn't make a meaningful difference.
This vacuum feels quite well-built. The assembly feels solid overall, with a balanced weight and no noticeable gaps in the construction. The wand is very sturdy on its own, and the wheels and buttons hold up well, too. Attaching accessories is straightforward, and the release latches feel secure when you do. That said, the dustbin feels noticeably more fragile than the rest of the vacuum, so it's worth handling with a bit more care when removing and emptying it.

This vacuum is relatively easy to store. It sits upright on the auto-empty dock to charge, and the two attachment tools can be stored directly on the dock as well.
Thanks to the auto-empty dock, the total dirt capacity is very high, even though the onboard bin itself is relatively compact at .5 quarts (.47L). The vacuum's own canister fills up quickly, and the motor stops when it does, flashing a red light to let you know it needs to be emptied. Docking the vacuum automatically empties the bin into the dock's larger dirt compartment, which has its own fill line to keep an eye on. Since its bagless throughout, there's no bag or filter to buy or replace.
Battery life is great, but how long it actually lasts depends on which power setting you're using. On ECO mode, the battery will last long enough to clean an entire home, but if you need to use BOOST mode for carpets, it'll eat up the battery life much faster. A battery life indicator keeps you updated on remaining charge as you go, and the included dock automatically recharges the vacuum each time you set it down.
Maintenance is easy but tedious, since it's spread across a fair number of parts on both the vacuum and the dock. You can pull tangled hair off the floor nozzle easily by hand, and a plate covering the roller helps prevent buildup, though you can't remove the roller itself for a deeper clean. Emptying the dock's bin kicks up a noticeable dust cloud, so it's best done outdoors if anyone in your home suffers from allergies.
You can find the full maintenance requirements and recommended frequency in the manual.
Recurring costs are essentially nonexistent. Shark doesn't specify a replacement schedule for either filter, and since the vacuum is bagless, there's no ongoing bag expense to factor in either.
If a filter does get damaged, you can buy new pre-motor filters and post-motor HEPA filters from Shark.
The Shark PowerDetect Speed Clean & Empty has a few extra features alongside its basic functionality. DETECT mode automatically adjusts suction based on how much debris it picks up as you clean, so you don't need to guess which setting a room needs. An LED indicator light lets you know how much debris the vacuum is detecting. A separate LED tracks battery status while charging.
If something goes wrong, the vacuum also displays specific error codes, which are listed in the manual.
This vacuum is relatively lightweight and portable, so it's easy to carry between rooms or up and down stairs without it feeling like a workout.
This vacuum is easy to maneuver, largely thanks to its MultiFLEX wand, which lets you clean under low furniture without bending over. One downside is that the upholstery tool has a fixed angle that makes it slightly harder to line up cleanly on furniture. It also can't handle rug tassels without getting caught, so you'll need to work around them.
Since this is a cordless vacuum, its range is limited only by the remaining battery life and the space left in its dirt compartment.
Filtration is mediocre and much worse than you'd expect from a HEPA-filtered vacuum. This comes as a bit of a surprise, since the Shark PowerDetect Cordless IP1251 uses the same filter and doesn't have this issue. This may be due to an improper seal from manufacturing or a defective filter. A smoke test around the exhaust vents shows a faint amount escaping near the top of the unit, right where the filter sits.
The dock's filter does an outstanding job of containing dust during the auto-empty process, capturing most particles so they aren't reintroduced into the air. The problem comes later: since the dock's own dustbin is bagless, you eventually have to empty it, which releases a cloud of dust. Whatever the auto-empty process keeps contained during daily use ends up escaping anyway once it's time to deal with the dock itself.
Though this vacuum is marketed as having powerful suction, its real-world suction through its floorhead is extremely low, even when using BOOST mode. That said, suction alone isn't necessarily a reliable indicator of cleaning performance. In this case, the vacuum performs better than its suction rating would suggest.
Airflow performance is decent, allowing the vacuum to lift larger debris without issue.
This vacuum is relatively quiet. Noise levels are similar on both bare floors and carpets. It is, however, noticeably louder in BOOST mode.
