SUNSMAI B75-2 Steam Mop Review: Is This 4-in-1 Cleaner Worth It?
The SUNSMAI B75-2 is a lightweight 4-in-1 steam floor cleaner combining dry sweeping, wet mopping, steam cleaning, and a self-cleaning cycle.
Its main use case is routine cleaning of compatible sealed hard floors when you want light debris pickup and hot-steam washing in one machine.
This SUNSMAI B75-2 steam mop review finds a corded cleaner with a powered roller, 450 ml clean-water tank, LED headlights, and a 180-degree lay-flat head. It targets buyers who value convenience and low lifting weight more than large tank capacity or vacuum-level suction.
🏆 My Quick Verdict
💡 Best For: Busy households with sealed hard floors that want light debris pickup, steam mopping, and self-cleaning in one relatively lightweight machine.
⚡ Key Specs:
1050W, 120V, 450 ml clean-water tank, 140 ml dirty-water tray, 19.6-ft cord, about 7.3 lb, 180° lay-flat cleaning.
✅ Bottom Line: The B75-2 offers unusually broad floor-cleaning functionality for its weight and adds useful touches such as LED lighting and an anti-scale filter. Its main trade-offs are the compact dirty-water capacity and the need to confirm steam compatibility with your exact flooring.
At a Glance
- Four functions combine dry sweeping, wet mopping, steam cleaning, and roller self-cleaning.
- The 450 ml clean-water tank supports up to about 20 minutes of cleaning on dry floors.
- A 140 ml dirty-water section means larger or wetter messes can require frequent emptying.
- The 19.6-ft cord provides solid room-to-room reach without battery management.
- The head lays flat to 180 degrees and includes LED lighting for low furniture and dark edges.
- Steam should be used only where both the mop maker and flooring manufacturer allow it.

Design & Build Quality
The B75-2 is designed around maneuverability rather than a large cleaning reservoir. At roughly 7.3 pounds, it is notably lighter than many wet-dry floor cleaners with similar multi-function layouts.
The aluminum-alloy handle tube, powered roller head, and separate water areas create a practical household form factor. A 180-degree lay-flat hinge helps reach beneath beds and low cabinets.
LED headlights reveal hair, crumbs, and dust along dark edges. The trade-off is a small 140 ml dirty-water compartment.
Setup, Installation & Ease of Use
- Fit the handle and aluminum tube securely into the main body before powering the unit.
- Install the roller brush and confirm its cover is fully locked before operation.
- Fill the 450 ml clean-water tank with plain water and seat it firmly in the machine.
- Use the dry-sweep mode first when the floor has loose crumbs or hair that do not need steam.
- Lower the handle before operation because the upright position is tied to the safety shutoff behavior.
- Use the cord hook after cleaning so the 19.6-ft cable stays controlled during storage.
- Empty and rinse the dirty-water and debris areas after use rather than leaving residue inside.
Core Performance & Feature Breakdown
The B75-2 is strongest when used as a daily all-in-one hard-floor maintenance machine. Its rotating roller can collect light dry debris while the steam mode loosens sticky residue and dried spots.
Manufacturer-linked listings describe steam cleaning at up to 194°F and up to about 20 minutes from the clean-water supply on dry floors. That suits kitchens, hallways, and medium cleaning sessions.
Power-assisted drive reduces pushing effort, while the lay-flat joint reaches under furniture. Dry debris pickup still should not replace a full-size vacuum for heavy grit, large particles, or carpets.
Expert Insight
Treat floor compatibility as a two-part check: the steam mop must permit the surface, and the flooring manufacturer must also permit steam. A “sealed hard floor” label on the mop does not override a wood or laminate warranty that prohibits heat or moisture.
Key Features Explained
4-in-1 Floor-Care System
The machine combines dry sweeping, wet mopping, steam cleaning, and roller self-cleaning. It reduces separate passes for light debris and sticky floor soil.
NA-IX Anti-Scale Filtration
A replaceable water-softening cartridge is designed to reduce mineral buildup from tap water. The filter remains a consumable component that eventually needs replacement.
180° Lay-Flat Head With LED Lights
The head folds nearly flat under low furniture, while front lighting makes debris easier to spot in dim corners and along edges.
Self-Cleaning Roller Cycle
The self-cleaning function helps rinse the roller after use. The tray, roller area, and wet components still need emptying, rinsing, and drying.
Real-World Usability & Maintenance
In practical terms, the machine favors frequent light cleaning over large-volume mess recovery. The 450 ml clean tank is reasonable for its weight, but the much smaller dirty-water area is the limiting capacity.
After cleaning, run the self-clean function, empty the separated debris and dirty-water areas, then rinse and dry removable wet components.
The long cord avoids battery-runtime concerns but still needs cable management. Store the unit upright without wet debris or standing water in the tray.
Premium Pros & Cons
Pros
- Four cleaning functions reduce the need to switch between separate floor-care tools.
- About 7.3 pounds is relatively easy to carry between rooms or floors.
- The 19.6-ft cord provides good reach without charging downtime.
- Lay-flat steering and LED lights improve cleaning under furniture and along dark edges.
Cons
- The 140 ml dirty-water compartment can fill quickly during wetter cleaning jobs.
- Dry-sweep pickup is not a substitute for strong vacuum suction on heavy debris.
- Steam use requires careful flooring-compatibility checks, especially on wood and laminate.
Common Issues & Fixes
Dirty-water tray fills too quickly: Wet floors or heavy liquid pickup can overwhelm the 140 ml capacity. Work on mostly dry floors and empty the tray before it reaches its limit.
Steam does not start: An empty or poorly seated clean-water tank can interrupt steam generation. Refill the tank, reinstall it securely, and allow the unit to heat before retrying.
Roller or warning light problem: Debris can jam the brush or prevent the cover from locking correctly. Unplug the machine, clear the obstruction, and reseat the roller cover before restarting.
What to Know Before You Buy
The most important pre-purchase check is your flooring warranty. SUNSMAI lists several sealed hard-floor types, but some hardwood and laminate manufacturers still prohibit steam regardless of the cleaner’s compatibility claim.
The machine is corded, so buyers prioritizing cordless freedom should look elsewhere. In exchange, it avoids recharge pauses.
A warranty card is listed among the included components, but the public product information reviewed does not state a verified warranty duration. Confirm the current warranty term with the seller or manufacturer before purchase.

Is It Worth It?
The B75-2 is worth considering when one machine can replace several steps in your normal hard-floor routine. Light debris pickup, steam, wet cleaning, and self-cleaning create genuine convenience.
Its value depends on accepting the small dirty-water capacity and corded design. If those limitations fit your routine, the feature-to-weight balance is strong.
Final Verdict
The SUNSMAI B75-2 is a practical 4-in-1 choice for buyers who want lightweight handling, powered roller assistance, steam cleaning, and easy under-furniture reach in one corded machine.
Choose it for compatible sealed hard floors and everyday messes, but do not treat its dry-sweep function as a full vacuum replacement or assume every sealed wood or laminate floor is steam-safe.
Frequently Asked Questions
Can the SUNSMAI B75-2 be used on hardwood floors?
Only when the exact hardwood manufacturer allows steam cleaning. SUNSMAI lists sealed hardwood as compatible, but flooring care instructions should take priority if they prohibit steam.
Can it clean laminate flooring?
It is listed for sealed laminate, but you still need written flooring approval for steam. Laminate seams and edges can be vulnerable to heat and moisture even when the surface is described as sealed.
How large are the water tanks?
The clean-water tank is 450 ml and the dirty-water section is 140 ml. The smaller recovery capacity is the practical limit during wet or heavily soiled cleaning.
How long can it run on one clean-water fill?
Public product information lists up to about 20 minutes on dry floors. Actual duration can vary with steam use, floor condition, and how often the machine pauses.
What maintenance does the B75-2 require?
Run the self-clean cycle as directed, then empty, rinse, and dry the wet components. The roller area should also be checked for hair and debris, and the anti-scale cartridge will eventually need replacement.
What warranty does it have?
A warranty card is listed in the included components, but a verified warranty duration was not found in the public sources reviewed. Confirm the current warranty term with the seller or SUNSMAI before buying.
