You know that feeling when you've finally given up on a rug? Maybe it's a coffee stain that’s moved in permanently or a "gift" from a new puppy that just won't quit smelling. Most of us just cover it with a coffee table and call it a day. But honestly, the Shark CarpetXpert with StainStriker has changed the math on whether you actually need to call a professional or just toss the carpet entirely.
It’s not just another bulky shampooer.
Most people assume all carpet cleaners are basically the same—some water, some soap, and a brush that spins. But the way this thing handles stains is actually pretty clever. It uses two separate cleaning paths. You’ve got your standard deep cleaning for the whole floor, but then there's the StainStriker tech. This isn't just marketing fluff. It’s a dedicated handheld system that mixes two different chemicals—an OXY multiplier and a deep-clean formula—right at the moment of impact.
Why the dual-tank system actually matters
If you’ve ever used a traditional carpet cleaner, you know the drill. You mix the soap and water in one big tank. By the time you get to that stubborn red wine spot, the solution is already diluted and half-cold.
Shark did something different here.
By keeping the high-concentrate OXY formula in its own separate tank, it stays "fresh" until you pull the trigger on the hand tool. When those two formulas hit the carpet together, they activate. It’s sort of like those two-part epoxy glues, but for getting gunk out of fibers.
It works.
I’ve seen it pull up stuff that’s been sitting for months. We're talking 20x the stain-striking power compared to just using a standard formula alone. It’s the difference between fading a stain and actually erasing it.
The suction is the real hero
Suction power is where most home machines fail. They leave the carpet soaking wet for three days, and then your house starts smelling like a wet basement. Not great.
The Shark CarpetXpert with StainStriker has some of the strongest suction I’ve seen in a consumer-grade machine. During testing by experts like Vacuum Wars, it consistently pulled more water back out of the pile than its competitors.
They included a "Dry Only" mode.

This is huge. Once you’re done scrubbing, you can go back over the area without spraying any more water. It just sucks. And it sucks hard. Most carpets end up dry to the touch in about 4 hours, which is lightyears ahead of the old-school machines that left you tiptoeing around for 24 hours.
It’s not all sunshine and roses (The Tank Problem)
Let’s be real for a second. There is one thing that drives people absolutely nuts about this machine: the tanks are small.
If you are trying to clean a 2,000-square-foot house in one go, you are going to be making a lot of trips to the sink. The dirty water tank fills up fast. Like, surprisingly fast. You’ll be mid-groove, and suddenly the motor pitch changes because the float valve snapped shut. Time to empty it again.
It’s a trade-off.
Shark clearly prioritized maneuverability over capacity. The machine is much lighter than a Rug Doctor or a big Bissell, coming in at around 18 pounds. It’s easy to carry up the stairs, but you pay for that lightness with frequent refills. If you have a massive open-concept living room, this might feel like a chore. For apartments or standard-sized bedrooms, it’s fine.
Dealing with the "Pet Factor"
If you’re a pet owner, the Shark CarpetXpert with StainStriker is basically a requirement.
They have a specific tool for "solids." Yeah, we’re talking about the gross stuff. It has a separate little trap so the... uh... "material" doesn't actually go through the long hose and into the main machine. This prevents that lovely situation where your carpet cleaner starts smelling like a kennel every time you turn it on.
Which model should you actually get?
Shark likes to make things confusing with model numbers. You'll see the EX201, the EX150, and the EX301 HairPro.
- The EX150: This is the "basic" one. It’s great if you just want to clean floors, but it lacks some of the fancy handheld tools.
- The EX201: This is the sweet spot. It includes the StainStriker handheld system and enough attachments to do your stairs and the car seats.
- The EX301 HairPro: This one is for the people whose carpets are 40% golden retriever fur. It has a specialized brush roll designed specifically to keep hair from wrapping and clogging the intake.
Getting the most out of it
Don't just fill it with boiling water and start sprinting across the room. That’s how you get mediocre results.
Slow down.
The brush roll needs time to agitate the fibers. I usually recommend one slow pass forward while holding the trigger, one slow pass back, and then two or three "dry passes" to get every drop of moisture out. If you’re using the StainStriker tool on a tough spot, let the solution sit for about 30 seconds before you start sucking it up. Give the chemistry a chance to work.
Also, a pro tip: use the Rinse and Go feature. On the top of the tank, there’s a little port where you can plug the hand tool in to flush out the hose. Do this every single time you finish. If you don't, the leftover dirty water in the hose will eventually start to stink, and no amount of OXY will fix a moldy hose.
Final thoughts on the investment
Is it worth the $250 to $300 price tag?
If you have kids, pets, or high-traffic areas, yeah. It honestly pays for itself after about three uses compared to renting a professional machine. Plus, you don't have to worry about whose gross house the rental machine was in before it got to yours.
The Shark CarpetXpert with StainStriker isn't perfect—I really wish the tanks were 50% larger—but in terms of sheer cleaning power and drying speed, it's currently at the top of the heap. It turns a "we need to replace this carpet" situation into a "oh, it's actually grey, not brown" situation.
To get started, make sure you clear the floor of all small debris first. This is a deep cleaner, not a vacuum, and while it can handle some hair, it'll last much longer if you give the area a thorough sweep with your regular vacuum before you start the wet work. Stick to the official Shark formulas to avoid clogging the internal filters, and always empty both tanks before you put it away for the season.
