What's in the Box and First Setup
There's a little assembly, but nothing that needs the manual. You get the vacuum itself, the flex wand, the brush roller head, and the crevice tool.
The first thing to do is charge it. Plug the charger straight into the port on the vacuum — you don't have to pull the battery out to charge it, though the battery does come out if you want it to. There are three indicator lights that tell you where you're at, and a full charge takes a few hours. Then the wand clicks onto the vacuum with an electrical connection that lines up, and the head clicks onto the wand. Done.
How You Actually Run It
This one is manual, and I mean that as a good thing — you're in control. There's no trigger to hold down. You press the power button, hold it a beat, and it stays on until you turn it off. That alone makes a long clean easier on your hand.
There are two switches to know. The first is the floor-type switch: hardwood or carpet. That sets how fast the brush roller spins. On hardwood you want it slower so it isn't flicking debris across the room; on carpet you want it faster so it's digging in. Your suction stays the same either way — this switch is only about roller speed. The second is the suction level: low, medium, and boost. Boost hits harder and drains the battery a lot faster. Medium is where I lived. The display shows you the battery percentage the whole time, so you always know what you've got left.
Cleaning Performance: What It Actually Picked Up
Hard Floors
Hardwood is where this vacuum shines, and I don't just mean the cleaning. The soft front roller pulls dirt in while the finned roller keeps contact, and the soft roller genuinely polishes the floor as it goes. It rolls so easy that you're barely pushing it. The LED headlight is on the front, and it does exactly what you want — it shows you dirt you'd have walked right past.
Carpet
I switched the mode over to carpet, put the suction back to medium, and cleaned up a big mess. It did a great job, and honestly the part that surprised me was how easy it still was to push back and forth. A lot of cordless vacuums fight you on the carpet. On boost it's a little harder to move, which makes sense — more suction means more grab.
Long Hair and Pet Hair
After the mess test I flipped the head over and checked for hair wrap. It did a good job — maybe a couple of hairs, but not enough to go find the scissors. There's a comb built in behind the bristles that keeps working on long hair while you clean. Worth knowing: the soft front roller comes out so you can wash it and set it in the sun to dry, then it clicks back in — put the side in first, engage the gear, and snap it down. The rear roller does not come out, so the comb is doing that job for you.
The Flex Wand — More Useful Than It Sounds
Press the button and the wand bends over on itself. Two things that gets you. First, storage: it folds down so you can stand it in a closet instead of leaning a five-foot pole against a wall. Second, and this is the one you'll use every day, you can press it mid-clean and drop the vacuum down low to get under furniture without getting on your knees. Click it back and it's a normal stick vacuum again.
Stairs and Above-Floor
You don't have to use the wand at all. The tool clicks straight onto the hand vac, which makes stairs genuinely easy — you're carrying a small unit up the steps instead of wrestling a full stick vacuum. Same for the car and the couch.
Battery Life
Shark rates it at up to 60 minutes, and here's the fine print you should know: that's measured at the hand vac in eco mode, not with the floor head spinning. So real-world with the head down and the roller turning, you'll get less than the number on the box. Low suction was still fine for regular pickup, so eco isn't a throwaway mode. Boost eats the battery. The battery is removable, which I like a lot — down the road when it won't hold a charge like it used to, you buy a battery, not a vacuum.
Maintenance Reality
Emptying is a one-lever job. Carry the bin over the trash can, push the lever, and everything drops out. Every so often you may have to reach in and pull off a few long hairs that wrapped around the inside — that's normal for any cordless. For a deeper clean, press the release on the other side and the whole unit comes off. Inside you've got the HEPA filter plus foam filters on both sides. The foam ones are reusable: wash them, let them dry all the way, then drop them back in — bottom in first, rotate until it clicks. If you ever get a clog, there's an access cover on the head you undo to pull the blockage out.
What I'd Change About the Shark IZ662H
- Let the rear roller come out for deep cleaning, the way the front one does.
- List the runtime for the floor head running, not eco mode on the hand vac.
- Include more tools in the box for what this costs.
Is It Worth It?
For a house with a lot of hardwood and some carpet, yes — this is an absolute Just A Dad Approved cordless. It cleans great, it's easy to push, the filters wash out, the battery comes out, and the flex wand earns its keep. The honest caveat is where it sits on price: this is a premium cordless, and Shark does run sales on their cordless line, so it's worth checking what it's going for before you pull the trigger.
