Our pick: The Shark Steam & Scrub S7201 is the best steam mop for grout cleaning — its rotating pads scrub over 150 times per minute while a targeted Steam Blaster jet attacks the grout lines, delivering up to 3x better stuck-on stain removal than traditional steam mops. For grout plus everything above the floor, the Bissell PowerFresh Lift-Off Pet adds a detachable handheld steamer with a dedicated grout brush.
Grout is the hardest thing a steam mop is asked to clean: it’s porous, recessed below the tile surface, and it holds onto years of embedded grime. A basic flat steam mop pad just glides over the top. The models below earn their place with scrubbing action (rotating pads or scrub brushes), concentrated steam jets, and attachments designed to get down into the grout line — plus the sustained high heat that actually loosens embedded dirt.
| Steam mop | Type | Key grout feature | Heat-up |
|---|---|---|---|
| Shark Steam & Scrub S7201 | Scrubbing mop | Rotating pads + Steam Blaster | 60 sec |
| Bissell PowerFresh Deluxe 1806 | Steam mop | SpotBoost scrub brush | 30 sec |
| Bissell PowerFresh Lift-Off Pet 1544 | 2-in-1 mop + handheld | 13 tools incl. grout brush | 30 sec |
| Dupray Neat | Canister steamer | 275°F steam + detail brushes | 8 min |
| Bissell PowerFresh Pet 19404 | Steam mop | Flip-down EasyScrubber | 30 sec |
1. Shark Steam & Scrub S7201 — Best Overall for Grout
The S7201 is the only traditional steam mop here that scrubs instead of just steaming: two rotating DIRT GRIP pads spin at over 150 scrubs per minute, doing the mechanical work that grout demands, while steam loosens the grime underneath. Shark claims up to 3x better stuck-on stain removal than traditional steam mops, and for grout lines that’s the difference between “lighter” and “actually clean.”
The Steam Blaster is the grout-line weapon — a targeted jet of steam fired at the touch of a finger for stubborn spots — and three steam modes (Light, Normal, Deep) let you match intensity to the job. LED headlights reveal grime hiding in the grout, the 1,120W heater is ready in about 60 seconds, and the 4.4-star rating from over 1,000 Amazon reviews backs up the performance. It typically sells around $180.
Pros: Rotating scrubbing pads do the work for you; Steam Blaster targets grout lines; 3 steam modes; chemical-free sanitization (99.9% of bacteria); LED headlights.
Cons: Heavier than basic steam mops at ~8 lb; pads need regular washing.
| Spec | Detail |
|---|---|
| Power | 1,120W |
| Scrubbing | Rotating pads, 150+ scrubs/min |
| Steam modes | Light, Normal, Deep + Steam Blaster |
| Tank | 350 ml (10.8 fl oz) |
| Heat-up | ~60 seconds |
| Features | LED headlights, 4 washable pads, filling flask |
2. Bissell PowerFresh Deluxe 1806 — Best Value Steam Mop
The PowerFresh Deluxe is the best-selling steam mop in America for a reason, and it’s a strong grout cleaner at about $103–$115. The built-in SpotBoost brush flips down to concentrate scrubbing power on tough spots — exactly what dingy grout lines need — while variable steam (high/low) lets you hit grout with full heat.
It heats up in just 30 seconds, the 19-ounce tank covers a good-sized tile floor per fill, and the 12-inch cleaning path moves fast across open tile. The steam sanitizes, eliminating 99.9% of germs and bacteria with water alone, and scent discs leave the room smelling fresh. For straightforward tile floors with dirty grout, this is the value sweet spot.
Pros: Excellent price; SpotBoost scrub brush for grout; 30-second heat-up; large 19 oz tank; sanitizes without chemicals.
Cons: No rotating pads — you supply the elbow grease; no above-floor attachments.
| Spec | Detail |
|---|---|
| Power | 1,500W (class) |
| Tank | 19 oz (560 ml) |
| Cleaning path | 12 inches |
| Heat-up | 30 seconds |
| Steam control | High / low |
| Features | SpotBoost brush, scent discs, 2-year warranty |
3. Bissell PowerFresh Lift-Off Pet 1544 — Best for Grout + Above-Floor Cleaning
Grout cleaning doesn’t stop at the floor — shower grout, backsplash lines, and countertop edges need steam too. The Lift-Off Pet’s removable handheld pod detaches from the mop body, and the 13 included tools feature a dedicated grout brush, angle concentrator, bristle brushes, and extension hose for reaching every grout line in the bathroom.
As a floor mop it’s fully capable: 1,500W of steam power, 30-second heat-up, SmartSet steam control, and a flip-down EasyScrubber for sticky spots. The 399 ml tank is on the smaller side, but the 25-foot cord means you can work a whole bathroom without replugging. It lists around $145 and is a long-time top-rated steam mop.
Pros: Detachable handheld with grout brush; 13 versatile tools; long 25-ft cord; strong 1,500W steam; pet-odor scent discs.
Cons: Smaller tank needs refills on big floors; the full tool kit takes storage space.
| Spec | Detail |
|---|---|
| Power | 1,500W |
| Tank | 399 ml |
| Heat-up | 30 seconds |
| Cord | 25 feet |

4. Dupray Neat — Best Canister Steamer for Deep Grout Restoration
When grout is years-neglected and mops aren’t cutting it, bring the canister: the Dupray Neat generates superheated steam up to 275°F (135°C) — far hotter than any stick steam mop — and holds it for up to 50 minutes per fill thanks to the large 54-ounce tank. Heat is what dissolves embedded grout grime, and nothing in this price class makes more of it.
The 17-piece kit includes nylon detail brushes, a brass brush for the toughest buildup, a steam lance for pinpoint grout-line work, extension tubes, and a floor tool with microfiber pads for finishing tile. It’s chemical-free (kills 99.9% of bacteria and viruses per lab testing), and the 8-minute heat-up is the price of that boiler-grade steam. It typically sells in the $150–$260 range.
Pros: 275°F superheated steam; 50 minutes of continuous steam; brass + nylon detail brushes; huge accessory kit; chemical-free sanitizing.
Cons: 8-minute heat-up; bulkier to store than a stick mop; overkill for light maintenance.
| Spec | Detail |
|---|---|
| Power | 1,500W |
| Max steam temp | 275°F (135°C) |
| Tank | 54 fl oz |
| Continuous steam | Up to 50 min |
| Heat-up | 8 minutes |
| Kit | 17 pieces: brushes, lance, extension tubes, floor tool |
5. Bissell PowerFresh Pet 19404 — Best Budget Pick
The PowerFresh Pet (19404) brings the core PowerFresh experience — including the flip-down EasyScrubber for grout lines — down to around $93. You get the same 30-second heat-up, variable steam control, and chemical-free sanitization as the Deluxe, in a proven design with a huge owner base.
It’s the right pick when the grout job is maintenance rather than restoration: regular steam passes keep grout from getting dingy in the first place, and at this price there’s no excuse not to. The included microfiber pads are washable, and Bissell’s scent discs handle the pet odors that often accompany tile floors.
Pros: Around $93; EasyScrubber for grout; fast heat-up; proven reliable design; washable pads.
Cons: Smaller feature set than the Deluxe; no scrubbing pads or handheld attachments.
| Spec | Detail |
|---|---|
| Heat-up | 30 seconds |
| Steam control | Variable |
| Features | Flip-down EasyScrubber, scent discs, washable microfiber pads |
| Sanitization | 99.9% of germs and bacteria with steam alone |
How to Clean Grout With a Steam Mop
Technique matters as much as the machine. Work in small sections and move slowly — steam needs a few seconds of dwell time to loosen embedded grime, so resist the urge to speed across the floor. On the first pass over neglected grout, use the highest steam setting and let the scrub brush or rotating pads do the work; follow with a microfiber pad pass to lift the loosened dirt before it resettles.
Two cautions: don’t hold concentrated steam in one spot on unsealed or damaged grout — the heat and pressure can erode it — and always vacuum or sweep first so you’re not steaming loose grit into the grout lines. For shower and backsplash grout, the Lift-Off Pet’s handheld tools or the Dupray’s steam lance beat any floor mop. And if your mop’s output seems weak, mineral buildup is the usual culprit — read our how to descale a steam mop guide before you assume the machine is dying.

FAQ
Does steam actually clean grout, or just lighten it?
Real steam cleaning lifts embedded dirt out of porous grout — it’s not just cosmetic. But badly neglected grout may need multiple passes plus a detail brush (or the Dupray’s 275°F steam) to fully restore.
Can steam damage grout?
On sealed, intact grout, no — residential steam mops are safe. Avoid blasting unsealed, cracked, or crumbling grout with concentrated steam, and don’t use steam on unsealed natural stone.
Should I seal grout after steam cleaning?
Yes — that’s the pro move. Steam cleaning strips old sealer along with the grime, so re-sealing afterward keeps the grout cleaner longer and makes the next steam session easier.
How often should I steam clean grout?
Kitchen and entryway grout benefits from monthly steam passes; bathrooms every 2–3 months. Regular light maintenance beats an annual restoration marathon.
Do I need a special attachment for grout lines?
It helps a lot. A scrub brush, grout tool, or rotating pads (like the Shark’s) clean grout dramatically better than a flat pad alone. For shower grout, a handheld steamer with a detail brush is the right tool.
Can I use vinegar or bleach with a steam mop for grout?
Don’t add anything to the water tank — use distilled water only to prevent mineral buildup. You can pre-treat grout with a cleaner and wipe it before steaming, but never put chemicals through the boiler.
Final Verdict
For grout cleaning, the Shark Steam & Scrub S7201 is the clear winner — rotating scrubbing pads plus the Steam Blaster do what flat mops can’t. The Bissell PowerFresh Deluxe 1806 is the value pick for tile floors, the PowerFresh Lift-Off Pet 1544 covers grout above the floor too, the Dupray Neat brings restoration-grade 275°F steam, and the PowerFresh Pet 19404 keeps maintenance cheap.
