Best Steam Cleaner for a Mattress

For a mattress, choose drier steam and a fabric tool, and keep moving: our top pick is the Vapamore MR-100 Primo. Bob Vila says its drier, hotter steam shortens drying time, which is what matters most on something you sleep on. Check your warranty first if you own memory foam: Tempur-Pedic says its mattress should never become wet, and Tom’s Guide warns steam risks voiding many warranties.

Best for mattresses#1

Vapamore MR-100 Primo

A compact canister known for hotter, drier steam, which matters most on things that should not stay wet. Bob Vila calls it its upgrade pick for bed bugs because that steam shortens drying time, and detailing retailer Detail King sells it for car upholstery, carpets and dashboards.

Why it stands out

  • Vapamore lists 51 psi, 250°F at the boiler and 40 ml of steam per minute.
  • 50–60 minutes per tank from a 1.6 L stainless steel boiler.
  • A clothes and fabric tool with cotton cover, plus a lifetime warranty on the boiler.
TypeCanister
Tank1.6 L boiler
Heat-up11 minutes
Run per fill50–60 minutes
Steam & reach51 psi; 250°F at boiler; 6 ft hose

Good fit if

  • You steam fabric, mattresses or car interiors and worry about leaving them wet.
  • You detail cars at home and want a real canister.

Skip it if

  • You want a machine that meets the 1-gallon guidance for bed bugs: 1.6 L falls short of it.
  • You want steam in a hurry: it takes about 11 minutes and must cool before refilling.

Detail King says vapor steamers cannot be returned once used, so check the seller’s policy before you buy.

Best all-rounder#2

Dupray Neat Plus

The Neat Plus fixes the two things that slow a canister down: it heats in 1–2 minutes rather than about 8, and you can refill it while you work rather than waiting for a boiler to cool. Apartment Therapy’s hands-on review says it removed caked-on grime from stone floors and grout and refreshed mattresses, pillows and a couch.

Why it stands out

  • Dupray lists up to 275°F steam and a 54 oz unpressurized tank.
  • A 17-piece kit, a 6 ft 6 in hose and a 16 ft cord in an 11 lb machine.
  • It is a different design from the original Neat, the model named in the CPSC recall.
TypeCanister
Tank54 oz, refill any time
Heat-up1–2 minutes
Run per fillUnlimited with refills
Steam & reachUp to 275°F; 6 ft 6 in hose; 16 ft cord

Good fit if

  • You want one machine for floors, grout, upholstery and mattresses.
  • You clean several rooms in a session and hate waiting for a refill.

Skip it if

  • You want a steam-strength dial: Apartment Therapy describes a single power button.
  • You only do quick floor touch-ups, where a 2-in-1 mop is less to haul around.

Let it heat fully: Apartment Therapy says it spits water if used early. On upholstery the same reviewer says results are harder to see than on hard surfaces. Dupray lists no pressure figure, so you cannot compare it with rivals on psi.

Best for occasional use#3

Wagner 505e

A true handheld from a brand with a US support line, with a flexible hose in the box at a Budget-tier price. The 505e is not part of the Wagner 900 Series recall. We found no major independent review of it, so treat it as a spec-sheet choice rather than a proven performer.

Why it stands out

  • An included flexible hose, upholstery nozzle, window tool and brushes (11 accessories, per Wagner).
  • 250 ml tank with 8–10 minutes of continuous steam, per Wagner.
  • 1-year warranty.
TypeHandheld with hose
Tank250 ml
Heat-up3–5 minutes
Run per fill8–10 minutes
Steam & reachFlexible hose, 11 accessories; 9 ft cord

Good fit if

  • You want a hose and a known brand at a low price.
  • You do short detail jobs.

Skip it if

  • You want independent test results; we could not find any.
  • You need long sessions; the unit must cool and depressurize before the cap comes off to refill.

Wagner’s figures conflict: 55 PSI on its product page, 36–43 psi in the manual. Do not buy this one for its pressure number.

Is your mattress memory foam?

Read the warranty before you buy anything. Foam can trap moisture, and some makers say it should never get wet.

Tips

Three things that make the difference

01

Vacuum, steam, vacuum

An NIEHS-led study found allergen decreases lasted longer after dry steam plus vacuuming than after one vacuuming, in upholstered furniture. Vacuuming also removes what steam loosens.

02

Stay damp, not wet

University of Minnesota says fabric may be damp but not wet, and to use a fan afterward. Purdue says vapor or dry steamers add less moisture, lowering water damage and mold risk.

03

Let it dry before making the bed

DoMyOwn, a retailer, says mattresses must air-dry fully before encasements go on. EPA says wet items should dry within 24 to 48 hours to prevent mold.

Honest note

Steam on a mattress is more about freshening than deep cleaning. We found little research on mattresses specifically: the best dust mite evidence comes from carpet and upholstery. Steam also has limited ability to penetrate fabric, per University of Kentucky, so it will not reach deep into a thick mattress.

FAQ

Questions people ask

Is it safe to steam clean a mattress?

Usually, if you keep it light and let it dry. Bissell, Dupray and NPIC list mattresses as steam targets. In a study on bed bugs, steam did not cause mold on mattress material after 30 days, under study conditions. Memory foam is the exception: Homes & Gardens quotes a cleaner saying foam can trap steam.

Will steaming void my mattress warranty?

It might, so check first. Tom’s Guide says steam cleaning memory foam risks voiding the warranty under many makers’ terms, without naming them. Tempur-Pedic’s care page says the mattress should never become wet. We could not find a named warranty that bars steam by that word. Read your own terms.

Does steam kill dust mites in a mattress?

It may reduce them near the surface. A University of Glasgow study found no live mites in steam-treated carpet over four months, and an NIEHS-led study found dry steam reduced allergen in upholstered furniture. Neither tested a mattress, and University of Kentucky notes steam has limited ability to penetrate fabric.

How long does a mattress take to dry after steaming?

We found no reliable figure specific to mattresses. Angi says upholstery commonly takes 2 to 8 hours, and a thick mattress could take longer. Run fans, open windows and wait until it is fully dry before making the bed. EPA says wet items should dry within 24 to 48 hours to prevent mold.

Can I steam a mattress with an iron or clothes steamer?

You can, but go carefully. Tom’s Guide has published a guide to steaming a mattress with an iron, and warns that steam on memory foam risks the warranty. University of Minnesota says not to use a clothing steamer for bed bugs, so do not rely on one for that job.

Will a steam cleaner remove mattress stains?

Probably not set-in ones. Bob Vila’s upholstery test found no cleaner removed vegetable oil, and food stains stayed on its best overall pick. Steam output was the biggest factor. For urine, the Humane Society of Sonoma County says to avoid steam because heat sets the odor. Use an enzymatic cleaner instead.
