Shark PowerPro Flex Pet Plus Cordless Stick Vacuum (IZ387H) Review

3 Months of Real Use in My Home

After three months of real messes across hardwood, carpet, and stairs, the Shark PowerPro Flex Pet Plus (IZ387H) proved itself a genuinely light, easy-to-handle cordless that cleans well and doesn’t tangle its roller. It’s not the top of Shark’s line — it skips the blue Dirt-Reveal light — and it’s the kind of vacuum I’d wait for a deal on. Here’s exactly how it held up.

What's in the Box and First Setup

In the box you get the vacuum, the MultiFLEX/pivot wand, the PowerFins power head, a yellow FurFins pet tool, an 8" crevice tool, the removable battery, a 6-foot charging cord, and the filters (a replaceable HEPA plus two washable foam filters). There’s no dock — you charge by plugging the 6-foot cord straight into the vacuum, and three lights show the charge level (all lit means fully charged).

Cleaning Performance: What It Actually Picks Up

Carpet and Hard Floor Performance

On both floors it did a good job. A big ground-coffee mess on carpet came up easily, and it stayed just as light and maneuverable on hardwood. The nice part is FloorDetect: on carpet it ramps up the brushroll (the light turns blue) and on hardwood it slows the roller (the light goes purple), switching seamlessly as you move between rooms — though the suction change itself wasn’t obvious to me.

Long Hair and Pet Hair

This is a strength. In a torture test with long and embedded hair, nothing wrapped the roller — the self-cleaning PowerFins and an internal hair-management comb kept it clear. The one catch showed up at cleanup: the hair had wrapped the cyclone filter instead, though there wasn’t much dirt built up around it. The yellow FurFins tool is there to pull hair off furniture.

Cat Litter Test

Cat litter was the one spot that needed a little extra. It didn’t scatter the litter around, but it left some behind on the first pass — a quick pull of the trigger for a boost pass picked up the rest. It cleans best pushing forward, and the trigger gives you max suction any time you want it.

Modes and How It Runs

Keep your expectations right here: there’s no bank of suction modes. It’s a push-button on/off, and the trigger gives you a momentary max-suction boost when you squeeze it. FloorDetect handles the brushroll-speed change between floors automatically, so day to day you’re not fiddling with settings — but if you want selectable power levels, this isn’t that vacuum.

Battery and Runtime

Shark advertises up to 50 minutes, measured at the hand vac in standard mode; I didn’t time my unit, so treat that as the headline number and expect less when the brushroll is working hard on carpet. FloorDetect helps stretch the battery by not over-driving the roller on hard floors. The battery is removable and charges on the 6-foot cord plugged into the vacuum.

Maintenance Reality

Emptying is a manual, point-and-drop job: release the canister, press the blue button, and everything drops out (there’s a little static cling, so blow it out now and then). The brush roll pops off with a button so you can wash it, and inside it there’s a comb for long-hair management. You get two reusable foam filters to wash and dry, plus a replaceable HEPA filter with an anti-allergen seal. One thing to remember from the hair test: check the cyclone filter, since that’s where hair tends to collect on this one.

Storage and Handling

At about 7.5 lb it’s light and easy to maneuver, and the wheel-to-handle length is about 42 inches. The MultiFLEX wand is the party trick — press the button and it bends so you can reach under furniture, or fold it over on itself to store. The wand also removes so the power head sits on the floor for stair jobs. The one habit to learn: it doesn’t stand on its own, so you fold it over or lean it somewhere.

What I'd Change About the Shark PowerPro IZ387H

• Add the blue Dirt-Reveal light — that’s the real reason to consider the step-up model.
• Make the bin a little bigger.
• A way to stand it up on its own would help.

Shark PowerPro IZ387H vs the Competition

Shark PowerPro IZ387H vs Shark PowerPro Flex with Dirt-Reveal (382H / 376H)

Same lightweight, auto-adjusting Shark experience, but the step-up models add the blue Dirt-Reveal light that shows you hidden dust as you clean. If that light matters to you, pay up for the 382H / 376H. If it doesn’t, this one does the core cleaning just as well.

Shark PowerPro IZ387H vs a Heavier Full-size Cordless Vacuum

This Shark trades outright suction power and a bigger bin for weight and easy handling. If you want the lightest thing that still cleans real messes and auto-adjusts between floors, it’s a strong pick; if you want maximum power and long runtime, look at a heavier flagship.
