SUNSMAI S65 PRO Wet Dry Vacuum Steam Mop Review (2026)
Is a corded 4-in-1 floor cleaner that combines vacuuming, steam mopping, wet pickup, and self-cleaning in one upright machine.
Its main use case is reducing separate vacuum-and-mop passes on compatible floors while providing strong suction for loose debris and hot steam for stubborn residue.

Design & Build Quality
The S65 PRO is a full-size upright floor washer rather than a lightweight stick steam mop.
At 19 pounds and roughly 46.8 inches tall, it provides space for separate water tanks, the powered cleaning head, suction hardware, and steam system.
The upright design should feel substantial during storage and carrying, although the integrated roller system does more of the floor-cleaning work than a passive mop pad.
Setup, Installation & Ease of Use
- Unbox the main unit, roller components, filter, cleaning tool, and supplied storage accessories before assembly.
- Install the appropriate roller and make sure the brush cover is fully locked into position.
- Seat both water tanks securely before filling the clean-water reservoir.
- Connect the 120 V corded unit to a compatible outlet before selecting a cleaning mode.
- Choose Eco suction for lighter debris or Max suction when stronger pickup is required.
- Use the dedicated carpet roller only according to the supplied surface instructions.
- Empty recovered dirty water and run the self-cleaning program after the cleaning session.
Core Performance & Feature Breakdown
The key performance advantage is simultaneous suction and steam, which lets the machine collect loose debris while heated moisture attacks stuck-on residue.
Its 6.5 kPa Eco mode is intended for routine pickup, while the 9.0 kPa Max setting provides stronger suction for heavier debris.
The 1800 RPM roller supplies mechanical agitation while the steam system produces 20–30 g/min at temperatures up to 212°F.
Separate clean- and dirty-water tanks also prevent recovered floor water from being continuously reapplied during the cleaning pass.
Expert Insight
The meaningful advantage is not simply high-temperature steam. Combining suction, roller agitation, fresh-water delivery, and dirty-water recovery can reduce the number of separate steps needed for a genuinely messy floor.
Key Features Explained
4-in-1 Cleaning System
The S65 PRO combines vacuuming, steam mopping, self-cleaning, and one-touch cord storage, reducing the need to switch between several floor-cleaning tools.
Dual Suction Modes
Eco mode delivers 6.5 kPa for routine cleaning, while Max mode increases suction to 9.0 kPa when debris requires stronger pickup.
Real-Time Water Circulation
A 780 ml clean-water reservoir supplies fresh water while recovered liquid goes into a separate 550 ml dirty-water tank, helping avoid repeated contact with already collected grime.
Automatic Self-Cleaning
The self-cleaning cycle uses the machine’s water system to rinse the roller and internal cleaning path, reducing manual cleanup after each session.
Real-World Usability & Maintenance
In practical terms, the machine makes the most sense in kitchens, dining areas, entryways, and pet-heavy homes where dry debris and sticky residue commonly appear together.
The trade-off is more maintenance than a simple steam mop because wet-dry machines still have a dirty-water tank, roller, filter area, and damp internal parts to manage.
Self-cleaning saves effort, but owners should still empty the dirty tank, inspect the roller, clean accessible debris, and let damp parts dry before storage.
Premium Pros & Cons
Pros
- Vacuum and steam functions can handle loose debris and stuck-on residue in one routine.
- Two suction levels provide more control than a single fixed-power setting.
- Separate clean- and dirty-water tanks keep recovered grime away from fresh water.
- Self-cleaning and LED status feedback simplify day-to-day ownership.
Cons
- The 19-pound upright body is considerably heavier than a basic steam mop.
- Steam compatibility must be confirmed for the exact flooring rather than assumed.
- Tanks, roller components, and filters still require regular hands-on maintenance.
Common Issues & Fixes
Reduced Suction
Debris around the roller, filter, or suction path can weaken pickup; inspect those areas and confirm both tanks are seated properly.
Roller Cover Does Not Fit Correctly
An incorrectly positioned cover can interfere with operation; remove it, align the attachment points carefully, and secure it before restarting.
Self-Cleaning Does Not Run Correctly
Insufficient clean water or incorrect positioning can interrupt the cycle; refill as required and make sure the machine is positioned according to the instructions.
What to Know Before You Buy
Floor compatibility should be checked before cleaning power. The listing recommends sealed hard floors, but that does not mean every hardwood, laminate, vinyl, or engineered floor manufacturer approves steam.
FloorsMop’s guide to steam mops explains how steam works, while the steam mop usage guide covers safer movement and floor-care practices.
Also consider the 19-pound weight, storage footprint, cord management, and post-cleaning tank maintenance. A specific manufacturer warranty duration is not clearly stated on the public listing, so verify current warranty terms before purchasing.
Who Should Buy It / Who Should Skip It
✅ Who Should Buy It
- Homes with steam-approved sealed floors and frequent mixed wet-and-dry messes.
- Pet owners regularly dealing with hair, tracked debris, and sticky floor residue.
- Buyers who prefer one corded machine instead of vacuuming and mopping separately.
✗ Who Should Skip It
- Anyone whose flooring manufacturer specifically warns against steam or high moisture.
- Shoppers who need a very lightweight cleaner for fast daily touch-ups.
- Users who want almost no tank, roller, filter, or drying maintenance after use.
Alternatives to Consider
BISSELL CrossWave HydroSteam Plus 35151
Best For: Buyers wanting a mainstream wet-dry cleaner with steam and clearly documented manufacturer support.
Main Advantage: It vacuums, washes, and steams while using two-tank separation and a self-cleaning cycle.
Trade-off: The 12.5-pound body is still substantial, and steam suitability depends on the surface.
Key Spec: 28 oz clean tank, 17 oz dirty tank, and 25-foot cord.
Tineco FLOOR ONE S5 Steam
Best For: Hard-floor users who want sensor-assisted cleaning and equal-size clean and dirty water tanks.
Main Advantage: Tineco combines vacuuming, washing, steam mode, digital feedback, and automatic self-cleaning.
Trade-off: Tineco specifies it for non-carpeted surfaces instead of offering the SUNSMAI’s carpet roller approach.
Key Spec: 0.75 L clean-water tank and 0.75 L dirty-water tank.
Is It Worth It?
The S65 PRO is most worthwhile when its combined functions replace multiple cleaning steps that you already perform regularly.
Its value comes from vacuum pickup, steam, roller agitation, dirty-water recovery, and self-cleaning working together rather than from any single specification.
If your flooring cannot safely handle steam or you only need quick light-duty cleaning, a simpler floor washer or microfiber system may make more sense.
Final Verdict
The SUNSMAI S65 PRO Wet Dry Vacuum Steam Mop is a capable all-in-one choice for homes that can safely use steam and regularly face both debris and sticky floor messes.
Its 9.0 kPa maximum suction, 212°F steam, separate water tanks, and powered roller are useful strengths, but its 19-pound body and maintenance requirements should be considered before buying.
Frequently Asked Questions
Can the SUNSMAI S65 PRO be used on hardwood floors?
Use it only when your hardwood flooring manufacturer specifically approves steam cleaning. The product listing recommends sealed hard floors, but individual wood finishes can react differently to heat and moisture.
Can the SUNSMAI S65 PRO clean carpets?
It includes a dedicated carpet roller and dry-pickup capability for carpet debris. Follow the supplied instructions rather than assuming high-temperature steam is appropriate for every carpet or rug.
How large are the water tanks?
The clean-water tank holds 780 ml and the dirty-water tank holds 550 ml. Keeping fresh and recovered water separate is one of the machine’s most useful practical features.
What warranty does the SUNSMAI S65 PRO have?
A specific warranty duration is not clearly stated in the publicly accessible product information. Check the current warranty and seller-service terms before ordering.
How should the SUNSMAI S65 PRO be maintained?
Empty the dirty-water tank, inspect the roller and filter area, run self-cleaning as instructed, and dry wet components after use. Regular maintenance helps prevent odor, debris buildup, and reduced suction.
Can I add floor cleaner or bleach to the water tank?
Only use liquids specifically approved by the manufacturer for this machine. Avoid adding bleach, vinegar, detergent, essential oils, or other chemicals unless the product instructions expressly permit them.
