5 Best Steam Cleaner for Mattress (Updated 2026)
Your mattress is one of the most used surfaces in your home, yet it’s also one of the most overlooked when it comes to deep cleaning. You spend a third of your life on it, and over time it collects sweat, dust mites, and bacteria deep inside the foam. A regular vacuum barely scratches the surface. That’s where a steam cleaner changes everything.
The best steam cleaner for mattress uses high-temperature steam to penetrate the fabric, kill bacteria, eliminate dust mites, and deodorize — all without a drop of chemicals. It’s safe for your family, your pets, and your sleep.
I’ve tested and researched the top options out there so you don’t have to. Here are my picks for 2026.
What Makes the Best Steam Cleaner for Mattress?
Not every steam cleaner is built equal, and when it comes to mattresses specifically, a few things really matter.
- Steam pressure shouldn’t be too high. This is actually a counterintuitive point that most roundups miss. For mattresses, you don’t want a machine blasting at maximum pressure. Too much steam soaks deep into the foam, making the mattress overly wet. That leads to longer drying times, potential mold growth inside, and foam degradation. A gentler, controllable steam output is actually ideal here.
- Temperature matters more than pressure. What kills bacteria and dust mites is heat. Look for a machine that reaches at least 200°F (93°C) at the surface.
- Drying speed is critical. The best units leave minimal moisture behind, allowing the surface to dry in 20 to 45 minutes.
- Attachments designed for fabric. A flat fabric pad or upholstery nozzle is what you need.
- Suction or extraction capability is a bonus. A machine that can both steam and vacuum out dirty moisture (like the BISSELL HydroSteam) takes things to the next level.
Best Overall: Dupray Neat Steam Cleaner
The Dupray Neat is the gold standard for homeowners who want a truly reliable, high-performance steam cleaner that works beautifully across the entire home, and yes, that includes the mattress.
This machine is built in Italy and has been a favorite of cleaning professionals and serious home cleaners for years. It’s not flashy or gimmicky. It just works, consistently and powerfully.

| Works on tap water, no need for distilled water | |
| Triangle tool + microfiber bonnet ideal for upholstery |
Testing Result
At 275°F, the Dupray Neat produces what’s classified as dry steam, meaning the steam carries very little liquid water. This is exactly what you want for mattresses. High heat, minimal moisture.
Running the triangle tool with a microfiber bonnet across the mattress, you can feel the surface getting hot fast. You can’t visually see it being cleaned (since there’s no suction), but the heat is doing the work underneath. After testing, the mattress surface smelled noticeably fresher, and any surface allergens were eliminated by the temperature alone.
With a 50-minute runtime at full tank, you can comfortably clean both sides of a queen mattress in one session — something budget handheld units simply can’t match. For anyone who wants a serious all-home steam cleaner that also handles the mattress extremely well, this is the one.

Steam Extractor: BISSELL Little Green HydroSteam
My personal pick, and the one I’d recommend first.
Out of everything I tested, the BISSELL Little Green HydroSteam 3618 is the most complete solution for mattress cleaning. Here’s why: most steam cleaners only push steam into the mattress. This one steams and uses suction to pull the dirty moisture back out.
That combination is what makes it stand out as the best steam cleaner for mattress if you want a truly thorough clean.
- EVERY PURCHASE SAVES PETS. BISSELL proudly supports BISSELL Pet Foundation and its mission to help save homeless pets.
- UP TO 50% BETTER CLEANING WITH HYDROSTEAM TECHNOLOGY. Steam, powerful suction and OXY formula remove set-in stains and tough, stuck-on, oily messes from carpet, upholstery and other surfaces.

| Compact and portable at 13 lbs | |
| Dual-tank system keeps clean and dirty water separate |
Testing Result
I used this on a memory foam mattress that hadn’t been deep cleaned in months. I switched to Steam Mode for the mattress surface specifically (to avoid over-wetting the foam) and ran the Tough Stain Tool slowly across the entire surface. The suction pulled out visible discoloration and the mattress was dry enough to sleep on within 30 minutes.
What really impressed me was the SteamWash mode on a sweat stain near the pillow area. One slow pass and the stain lifted significantly. The dual-tank system meant I could see exactly how much grime was being extracted — and it wasn’t pretty, but it was satisfying.
The HydroSteam technology, which combines steam heat with BISSELL’s OXY formula, improved cleaning performance by up to 50% compared to steam alone in testing. For mattress work, the Steam Mode (without cleaning solution) is the smartest choice.

Premium Pick: McCulloch MC1385 Deluxe
If you want the absolute most powerful, longest-lasting steam clean possible and you’re doing a full home deep clean on a regular basis, the McCulloch MC1385 is built for that kind of commitment. This is a serious machine.
- CHEMICAL-FREE CLEANING — Naturally deep clean without the use of harsh chemicals using hot, pressured steam to eliminate grease, grime, and stains from a wide range of surfaces including tile, grout, granite, laminate, appliances, grills, autos, and more.
- 23 ACCESSORIES — Equipped for steam cleaning jobs in and around your home including a floor mop, mop pads, nylon brushes, brass brush, angled nozzle, scrub pad, scraper, squeegee, & more. Conveniently store accessories on-board or in included storage bag.
It’s a canister-style unit, which means more water capacity, more accessories, and far more runtime than any handheld option. It’s not the most convenient choice for a quick Tuesday night mattress refresh — but for a monthly deep clean of the whole bedroom, it’s exceptional.
Key Specs
| Spec | Detail |
|---|---|
| Steam Temperature | Over 200°F |
| Steam Pressure | Up to 58 PSI (4 bar) — variable control |
| Water Tank Capacity | 64 oz |
| Runtime | Up to 120 minutes continuous |
| Heat-Up Time | ~12 minutes |
| Accessories | 23 pieces |

Pros and Cons
| Pros | Cons |
|---|---|
| 120 minutes of continuous steam — unmatched runtime | 12-minute heat-up time |
| Variable steam control, can dial down pressure for mattresses | Pricier than budget alternatives |
| 23 accessories for any surface imaginable | |
| Long 10-ft hose means you don’t have to drag the unit constantly | |
| 18-ft power cord — excellent reach | |
| Backed by 50+ years of McCulloch engineering |
Testing Result
The key with this machine on a mattress is the variable steam control dial. Turned to the lower setting, the steam output becomes gentler and much more appropriate for foam. Turn it too high and you risk over-wetting.
The 10-foot hose is a genuine advantage here — you can park the canister at the foot of the bed and reach the entire mattress surface without moving the unit. For someone tackling the whole bedroom in one session (mattress, carpet, tile bathroom, windows), the 120-minute runtime means you won’t run out of steam mid-job.
It earned its premium reputation for durability and cleaning power. The trade-off is convenience — this isn’t a grab-and-go machine. Set aside a chunk of time when you use it, and it will reward you.

Best Value: BISSELL PowerSteamer Heavy Duty 3-in-1
This is the pick for people who want real versatility without a premium price tag. The 2685A does a lot, it functions as an upright steam mop, an extended-reach overhead steamer, and a handheld steam cleaner in one unit. For mattress cleaning, you’ll use it in the handheld SteamShot configuration.

Testing Result
The 30-second heat-up is genuinely impressive. You plug it in, wait half a minute, and steam is flowing. Detached from the mop handle and used as a handheld unit, it’s easy to work across a mattress surface.
The fabric steamer attachment glides well over mattress fabric without snagging. Because the tank is small, a full mattress will require 2 to 3 refills — let the unit cool slightly each time before opening. The two steam levels are straightforward: use low for the mattress surface to avoid excess moisture.
It won’t match the runtime or power of the Dupray or McCulloch, but for the price, the versatility is excellent. If you’re also looking for a machine that mops your bathroom floor, cleans your kitchen counters, and does a quick mattress refresh, this delivers real value across all those tasks.
Best Budget: Phueut Pressurized Steam Cleaner
Don’t let the budget price fool you, the Phueut handheld has earned genuine praise from real users. For someone who just needs to sanitize their mattress periodically without spending $200+, this is an honest, capable little machine.

Testing Result
For mattress work, plan to refill 2 to 3 times to cover a full queen mattress. Each refill cycle means waiting for the unit to cool slightly before opening the safety cap — just part of working with a small tank. The 230°F steam is genuinely effective at sanitizing the surface and eliminating odors.
This is the one I’d recommend to someone in an apartment who wants to clean their mattress seasonally, without much storage space for a larger machine. Simple, light, functional, and the price is hard to argue with.

How to Use a Steam Cleaner for Mattress the Right Way
Getting the technique right matters just as much as choosing the right machine. Here’s a simple step-by-step approach that works for any of the cleaners above.
Step 1: Strip the bed completely.
Remove all sheets, pillowcases, mattress protectors, and toppers. Wash them separately. You want to work directly on the bare mattress.
Step 2: Vacuum the mattress first.
Run a vacuum with an upholstery attachment over the entire surface before steaming. This picks up loose dust, hair, and debris so the steam can penetrate deeper rather than just displacing surface dirt.
Step 3: Fill the water tank and let it heat up.
Use regular tap water for most machines (Dupray Neat is specifically designed for this). Follow the heat-up time in your model’s manual. Don’t rush this — proper steam temperature is what makes the cleaning effective.
Step 4: Choose the right attachment.
Use a flat fabric pad, upholstery nozzle, or triangle tool with a microfiber bonnet. Avoid hard nylon scrub brushes — they can damage the mattress fabric.
Step 5: Move slowly across the surface.
Don’t rush. Move the steam head in slow, overlapping rows — roughly 2 to 3 inches per second. Slower movement means more heat transfer and better bacteria elimination. Going too fast won’t give the steam time to penetrate.
Step 6: Use low steam pressure or dial it down.
If your machine has variable settings, use medium-to-low pressure on the mattress. This prevents over-wetting the foam inside.
Step 7: Pay extra attention to seams and edges.
Dust mites and bed bugs like to hide in the seams and piping around the mattress edges. Use a narrow nozzle or the jet attachment to hit those areas directly.
Step 8: Let it dry completely before making the bed.
This is the most important step. Leave the mattress uncovered for at least 2 to 4 hours, or until it feels completely dry to the touch. Open windows or turn on a fan to speed up drying. Never put sheets back on a damp mattress — this encourages mold and mildew growth inside the foam.
Step 9: Flip or rotate and repeat on the other side (if applicable).
If your mattress is flippable, steam the underside too. Even if it’s not designed to be slept on, the underside can accumulate moisture and mold over time.
Step 10: Clean your attachments after use.
Rinse or wipe down the tools after every session. Some machines (like the BISSELL 3618) have a self-clean cycle for the hose — use it to prevent buildup and odors inside the machine.
FAQs
Can I use any steam cleaner on my mattress?
Technically yes, but you need to be careful about steam pressure. Machines with very high pressure settings — like the McCulloch at 58 PSI — need to be dialed down when used on mattresses to avoid pushing too much moisture deep into the foam. Machines with gentler output or variable control are more forgiving.
How often should I steam clean my mattress?
Every 3 to 6 months is a good general guideline for most households. If you have allergies, asthma, pets that sleep on the bed, or young children, every 1 to 3 months is even better.
Will steam cleaning kill bed bugs?
Yes, but only if the steam actually contacts them directly and at sufficient temperature. Steam needs to reach at least 160°F at the point of contact to kill bed bugs and their eggs. The Dupray Neat at 275°F and the BISSELL HydroSteam are both effective for this. The key is moving slowly enough that the heat penetrates the seams and crevices where bed bugs hide.
Can steam damage my memory foam mattress?
It can if you use too much steam. Memory foam is sensitive to excessive moisture and should not be soaked. Use a machine with variable or gentle steam output, move slowly without lingering too long in one spot, and always allow thorough drying before re-making the bed.
Do I need to use cleaning solution when steaming a mattress?
No. For mattresses, plain water steam is best. Cleaning solutions can leave residue inside the foam that’s difficult to rinse out, and for sanitizing purposes, heat alone does the job. The BISSELL HydroSteam is the exception — its SteamWash mode uses cleaning solution for surface stains, but the Steam-only mode is recommended for the main mattress surface.
How long does a mattress take to dry after steam cleaning?
Usually 2 to 4 hours with good airflow. Using a steam cleaner with low moisture output (like the Dupray Neat, which leaves less than 5% water in its steam) speeds this up significantly. Open windows and run a fan to help.
Can steam cleaning remove sweat stains from a mattress?
Steam alone can lighten sweat stains and eliminate the odor-causing bacteria. For set-in stains, a machine with both steam and extraction — like the BISSELL Little Green HydroSteam — does a better job by actively pulling the stain out rather than just heating it.
Is it safe to steam clean a mattress with a pillow top?
Yes, but be especially gentle. Pillow tops have extra layers of padding that hold moisture more easily. Use the lowest steam setting and make sure it’s completely dry before covering it again.
Can I use a steam cleaner on a mattress that has a waterproof protector?
If the protector is on the mattress, remove it first and wash it separately. Steam the bare mattress, then put the clean protector back on once both are fully dry.
Will steam cleaning help with mattress odors?
Absolutely. One of the most noticeable results of steam cleaning a mattress is odor elimination. The high heat kills odor-causing bacteria and breaks down the compounds that make mattresses smell stale or musty over time. The difference after a steam session is usually immediate.
