Both make steam. One is a floor tool with a pad, and the other is a pressure device with attachments. Buying the wrong one is the most common mistake in this category.
Everyone in this category says they tested twenty vacuums. We have not tested any, and we say so. What we do instead is read the manuals, compile the published specifications, and work out what each machine costs to run for three years — the method is written out in full.

Buy the steam mop first. A steam mop is a floor machine: a tank, a heater and a pad on a wide head, built to cover square meters. A steam cleaner is a pressure device with nozzles and brushes, built for spots, grout lines, ovens and upholstery. If floors are the problem, the mop is the machine, and a cleaner will not substitute for it.
The difference is the head, not the steam
Both boil water and both deliver vapor. What separates them is what happens at the other end.
A steam mop puts that vapor through a wide, flat, padded head — the Bissell PowerFresh publishes a 12-inch cleaning path — and the pad does two jobs: it distributes the steam and it holds the loosened dirt. The whole machine is optimized for covering floor area with a person walking behind it.
A steam cleaner puts that vapor through a narrow nozzle at higher pressure, with attachments — detail brushes, squeegees, upholstery tools. There is often no pad at all, which means the dirt is loosened and then left for you to wipe up. That is exactly right for an oven door and exactly wrong for a hallway floor.
What each is genuinely good at
The jobs each format is designed for.

Yes — this is the entire design
No — narrow head, no pad, slow

Sealed hard floors, weekly
Yes
Technically possible, practically miserable
Carpet
No — see the note below
No
That last row matters and it is where people lose real money. Neither of these cleans carpet. Steam applied to carpet loosens soil and then leaves it in the pile, because neither machine extracts. The tool that removes soil from carpet is an extractor, and we cover that confusion in full because it is the single most expensive mistake in floor care.
Which to buy first
If your floors are the problem, buy the mop. Floors are the largest surface in any home and the one that visibly degrades fastest. A steam cleaner will do a beautiful job on your oven while your hallway stays dirty.
If floors are fine and the bathroom is the problem, buy the cleaner. Grout, shower screens, taps and tile edges are exactly what a detail nozzle is for, and no floor mop reaches them.
If you want one machine for both, look at the detachable formats — but read the floor head specification carefully, because a floor head bolted onto a handheld unit is usually narrower and less capable than a dedicated mop's.

Shark SteamSpot with Steam Blaster (S2001)A 500 ml tank and three steam modes at under 5 lb — the most usable combination of numbers on this page.
Bissell PowerFresh Steam Mop (1940A)Three steam settings, a flip-down scrubber and a 23-foot cord, with a two-year warranty that is double everything Shark offers.
Shark Steam & Scrub All-in-One (S8001)Rotating pads at over 150 scrubs a minute, and Shark publishes the test standard behind the 2x stain claim rather than just asserting it.
Shark Steam Pocket Mop (S3501)Double-sided pads flip mid-clean, which halves how often you stop to change them — a small idea that beats a bigger tank in practice.

01 · Best big tank under 5 lb
Shark SteamSpot with Steam Blaster (S2001)
A 500 ml tank and three steam modes at under 5 lb — the most usable combination of numbers on this page.
3 — Light, Normal, Deep, plus a targeted Steam Blaster burst
Stain-removal claim
Up to 50% better stuck-on stain removal versus a traditional steam mop
Pads
1 Dirt Grip pad and 1 stiffer scrub pad, both washable
Sanitization claim
Removes 99.9% of common household bacteria using water alone
Rated surfaces
All sealed hard floors
Every figure above is the manufacturer's own published number. Where a manufacturer publishes nothing, the row says "Not published" rather than an estimate.
What the numbers say
+500 ml is the largest tank here and it comes in under 5 lb, which no other machine on this page manages
+Three steam modes plus the targeted blaster
+Two pad types in the box — one for maintenance, one for scrubbing
Where it stops
−Only one of each pad, so you are doing laundry sooner than with the four-pad Steam & Scrub
−No rotating scrub head, so it is 50% better rather than the Steam & Scrub's 2x
−The 50% claim does not name its test standard, unlike the S8001's
Who it is for
Anyone who wants the fewest refills and the least weight, which is most people.
Skip it if
You need mechanical scrubbing. This is steam plus a textured pad; if a flat pad has already failed on your floors, buy the S8001.

02 · Best for tile and grout
Bissell PowerFresh Steam Mop (1940A)

Flip-down Easy Scrubber for dried-on messes and grout
Cord
23 feet
Cleaning path
12 inches
Sanitization claim
Kills 99.9% of germs, bacteria and viruses when used as directed
Warranty

Sealed hard floors — sealed hardwood, tile and ceramic, granite, marble
Every figure above is the manufacturer's own published number. Where a manufacturer publishes nothing, the row says "Not published" rather than an estimate.
What the numbers say
+Three steam settings — the only genuinely variable machine under $110 here
+Built-in flip-down scrubber is the correct tool for grout and nobody else at this price has one
+23-foot cord, the longest published here
+2-year warranty, double Shark's across the line
Where it stops
−6.2 lb, the heaviest steam mop on this page
−Scent discs are an optional consumable that quietly adds up if you start using them
−1,500 W is the highest draw here, which matters if the outlet is shared
Who it is for
Tile and grout kitchens and bathrooms, where the mess is baked on rather than dusty.
Skip it if
Your floors are all sealed hardwood. You are paying for a grout scrubber you will never flip down, and the lighter Shark units suit hardwood better.

03 · Best rotating-pad scrubber
Shark Steam & Scrub All-in-One (S8001)
Rotating pads at over 150 scrubs a minute, and Shark publishes the test standard behind the 2x stain claim rather than just asserting it.
Up to 2x better stuck-on stain removal versus traditional steam mops, per IEC/TC SC 59F (mustard), tested against the S1000
Pads
4 machine-washable Dirt Grip pads included
Lighting
LED headlights
Every figure above is the manufacturer's own published number. Where a manufacturer publishes nothing, the row says "Not published" rather than an estimate.
What the numbers say
+Names the test standard AND the model it was tested against — the most checkable performance claim on this site
+Three steam modes plus mechanical scrubbing, which is a genuinely different machine from a flat pad
+Four pads in the box, so you can clean the whole house before doing laundry
Where it stops
−11.83 fl oz is a smaller tank than the far cheaper S3601, and scrubbing uses water faster
−6.9 lb with rotating heads that pull the mop forward — an acquired feel
−Pads wear faster than on a static mop, because they are doing mechanical work
Who it is for
Kitchens with actual stuck-on messes, and homes where a flat pad has already failed.
Skip it if
Your floors are only ever dusty. You are buying a scrubber for stains you do not have, and the S3501 does maintenance cleaning for far less.

04 · Best pad value
Shark Steam Pocket Mop (S3501)
Double-sided pads flip mid-clean, which halves how often you stop to change them — a small idea that beats a bigger tank in practice.

+Double-sided pads: flip the head and keep going instead of walking to the laundry
+15.2 fl oz, 20% more than the S1000
+Filling flask included, which sounds trivial and is not
+Published bacteria-removal claim with the chemical-free qualifier stated
Where it stops
−Still a single steam output with no modes
−Rectangular head is worse in corners than a triangular one
−1-year warranty
Who it is for
Whole-floor cleans where the interruption you actually resent is swapping a dirty pad.
Skip it if
You want variable steam for a mix of delicate laminate and greasy kitchen tile. Buy the SteamSpot or the Bissell for that.

Both are rated for sealed surfaces
Whichever you buy, the surface restriction is the same and it comes from the manufacturers: sealed hard floors only. Shark publishes it across its steam mop line; Bissell publishes it for the PowerFresh 1940A. Heat plus moisture on an unsealed surface is a problem regardless of which nozzle delivered it. The full surface guide is here.
What we cannot tell you
How a specific steam cleaner performs, because this site does not review them — every machine on this page is a steam mop, and recommending a category we have not researched properly would be the same failure as claiming to have tested one. What we can do is explain the distinction clearly enough that you buy the right category, which is the part people usually get wrong.
Common questions
What is the difference between a steam mop and a steam cleaner?+−
The head. A steam mop puts vapor through a wide padded floor head designed to cover area, and the pad holds the loosened dirt. A steam cleaner puts vapor through narrow nozzles and detail brushes for spots, grout, ovens and upholstery, usually with no pad at all.
Can a steam cleaner clean floors?+−
Technically, and very slowly. Without a wide padded head there is nothing distributing the steam or collecting the dirt, so you are working square foot by square foot. If floors are the job, buy the mop.
Can a steam mop clean my oven or bathroom tiles?+−
No. A wide flat floor head cannot reach into an oven or along a shower screen. That is what a steam cleaner's detail attachments are for, and it is the strongest case for owning one.
Can either one clean carpet?+−
No. Both loosen soil and neither extracts it, so the dirt stays in the pile. The tool that removes soil from carpet is an extractor — a carpet cleaner — and confusing the two is the most expensive mistake in floor care.
Should I buy a 2-in-1 detachable machine?+−
It is a genuinely useful format, but read the floor head specification carefully. A floor head bolted onto a handheld unit is usually narrower and less capable than a dedicated mop's, so you are trading floor performance for versatility.
