You’ve probably seen the ads where a single swipe of a steam mop leaves a floor looking like a polished mirror. It’s a nice dream. But if you’ve actually spent your Saturday morning scrubbing dried pasta sauce off a tile floor, you know the reality is usually a lot more... damp. And annoying. Most steam mops are basically just glorified kettles on sticks. However, the Shark Professional Steam Pocket Mop S3601 has managed to hang onto its reputation for years while flashier, "smarter" gadgets have come and gone.
It's weird.
In an era of robot vacuums that can map your house and mops that talk to your phone, why are we still talking about a corded upright from Shark? Honestly, it’s because it does the one thing most people actually care about: it gets the grime up without leaving a soaking wet mess behind.
What makes the Shark Professional Steam Pocket Mop S3601 different?
Most people think steam is just steam. It isn't. If the steam is too "wet," you end up damaging your laminate or leaving streaks on your hardwood. If it’s too "dry," it doesn't actually sanitize anything. The S3601 hits a sweet spot because of the "Intelligent Steam Control."
Basically, you have three settings: Dust, Mop, and Scrub.
- Dust is for those quick passes where you just want to pick up pet hair or light surface dust without soaking the floor.
- Mop is your everyday setting.
- Scrub is for the high-traffic mudroom or the kitchen after a chaotic Sunday roast.
The "Professional" tag in the name isn't just marketing fluff. It refers to the larger water tank and the dual-sided "pocket" pads. Most mops use a single-sided microfiber cloth that gets filthy in five minutes. With this Shark model, you just flip the head over and keep going. You’re essentially getting double the cleaning surface before you have to swap pads. It’s a simple engineering choice, but it’s one of those things you appreciate most when you’re halfway through a large living room and don't want to stop.
The physics of the "Pocket" pad
Let’s get nerdy for a second. The Shark Professional Steam Pocket Mop S3601 uses a 180-degree swivel head, but the magic is in the microfiber. These aren't just flat rags. They are designed to hold the steam inside the "pocket" so the heat is evenly distributed across the entire surface of the pad.
Ever noticed how some steam mops leave a hot strip in the middle but the edges are cold? That’s what this design prevents. By trapping the steam within the pocket, the fabric stays at a consistent temperature. According to Shark’s internal testing, this allows the mop to eliminate 99.9% of common household bacteria like E. coli and staph. That’s a big deal if you have toddlers crawling around or a dog that treats the floor like a dinner plate.

The "Hardwood" controversy: Is it actually safe?
This is the question that keeps floor installers up at night. "Can I use a steam mop on my wood floors?"
The short answer: Yes, but only if they are sealed.
If you have gaps in your floorboards or the finish has worn off, the Shark Professional Steam Pocket Mop S3601—or any steam mop for that matter—is your enemy. Steam is pressurized water vapor. It will find those cracks, get into the wood fibers, and cause warping.
However, for modern, well-sealed hardwood, the S3601 is actually safer than a bucket and a string mop. Why? Because it uses significantly less water. A traditional mop leaves a film of water that sits there for ten minutes. The Shark’s steam evaporates in seconds. The trick is to keep the mop moving. Never let it sit idling on one spot of wood while you answer the door. That’s how you get white cloudy spots in your finish.
Real-world performance on tile and grout
Tile is where this thing shines. Grout is porous, and it loves to soak up dirty mop water. When you use a regular mop, you’re often just pushing dirty water into the grout lines.
The S3601 uses heat to break the molecular bond between the dirt and the surface. Because the microfiber pads have a bit of "shag" to them, they can reach slightly into the grout depressions. It won't replace a professional deep-clean for grout that hasn't been touched in a decade, but for maintaining a clean floor, it’s night and day compared to a Swiffer.
The design flaws nobody mentions
I’m not going to sit here and tell you it’s perfect. It isn't.

First off, the cord. It’s 22 feet long, which sounds like a lot until you’re trying to reach the far corner of a master bedroom and you’re two inches short. You will be unplugging and replugging this thing.
Second, the "pump" action. The Shark Professional Steam Pocket Mop S3601 doesn't have an electric pump. To get the steam flowing, you have to physically push the mop. The pumping motion of the handle is what generates the steam. Some people love this because there’s no motor to break. Others find it a bit of a workout. If you’re looking for a device that self-propels or does all the work for you, this isn't it. This is a manual tool.
Also, let’s talk about the water.
The manual says you can use tap water. Technically, you can. But if you live in an area with "hard" water—high mineral content—those minerals will eventually clog the internal heating element. It’s the same reason your coffee maker gets scaly. If you want this mop to last five years instead of eighteen months, spend the extra three dollars on a gallon of distilled water. Your floor (and your wallet) will thank you.
Carpet Glider: A gimmick or a godsend?
The S3601 often comes with a "Carpet Glider" attachment. It’s basically a plastic frame that the mop sits in so it can slide over rugs.
Don't expect it to "clean" your carpet. It won't remove a red wine stain or pull up deep-seated dirt. What it will do is "refresh" the carpet. The heat can kill dust mites and neutralize some odors. It’s great for high-pile rugs that have been flattened by furniture; the steam helps the fibers stand back up. Just keep your expectations realistic. It’s a steamer, not a rug doctor.
Comparing the S3601 to the newer "Scrub & Sanitize" models
Shark has released several newer versions since the S3601 hit the market. Some have rotating pads; others have "Steam Blaster" nozzles that shoot a concentrated jet of steam at a stain.

So why stick with the Shark Professional Steam Pocket Mop S3601?
Reliability.
The rotating pad models are cool, but they have more moving parts. More motors, more gears, more things to snap. The S3601 is a tank. It’s a very simple mechanical system. For many homeowners, the added complexity of the newer models doesn't actually result in a cleaner floor—it just results in a more expensive repair bill later on.
The S3601 provides a wider cleaning path (about 12 inches) than many of the newer, "sleeker" models. If you have a massive open-concept kitchen, you want that width. You don't want to be painting your floor with a four-inch brush.
Actionable Steps for the Best Results
If you’ve got an S3601 sitting in your closet or you're about to buy one, here is how you actually get the most out of it without ruining your floors:
- Vacuum first. Always. Steam mops are not vacuums. If you leave crumbs or hair on the floor, the steam mop will just turn them into a wet, gray paste that you smear across the room.
- Pre-soak the pads. Don't start with a bone-dry pad. Dampen it slightly under the tap and wring it out before attaching it. This helps the steam transfer through the fabric much faster.
- The "Ten-Second" Rule. For stubborn, dried-on gunk (like dried honey or mud), let the mop sit over the spot for about 5-10 seconds on the "Scrub" setting. Let the heat do the work so you don't have to use elbow grease.
- Wash the pads correctly. Never use fabric softener when washing the microfiber pockets. Softener coats the fibers and makes them less absorbent, which leads to those annoying streaks on your floor. Use a clear detergent and air dry them if you can.
- Store it empty. When you're done, empty the water tank. Leaving water sitting in the reservoir for weeks can lead to a musty smell that is almost impossible to get rid of.
The Shark Professional Steam Pocket Mop S3601 remains a staple for a reason. It’s an honest tool. It doesn't have an app, it doesn't need Wi-Fi, and it doesn't require expensive chemical refills. It just uses hot water to make your house feel less gross. In a world of over-engineered appliances, there’s something genuinely refreshing about that.
