Mattresses and carpets rarely become dirty overnight. Instead, it’s a gradual build‑up of sweat, dust mites, pet hair, spills, and everyday use that settles deep into the fibres, leaving them looking fine on the surface but far from truly clean. Regular vacuuming helps with loose dirt, but it can’t remove the hidden grime and allergens trapped below.
That’s where the best steam cleaner for mattress and carpet really earns its place. By using high‑temperature steam, it loosens embedded dirt, sanitises surfaces, and refreshes fabrics without relying on harsh chemicals.
Whether you’re trying to improve indoor hygiene, reduce allergy triggers, or give high‑traffic areas a proper deep clean, choosing the right steam cleaner can make a noticeable difference throughout your home.
Top Picks







Kärcher SC 3 EasyFix Steam Cleaner
You get fast heat-up, strong constant steam and a sensible size tank for longer cleaning sessions. It’s built with descaling in mind and performs reliably across hard floors, bathrooms and many domestic surfaces.
The Kärcher SC 3 EasyFix sits toward the top end of domestic steam cleaners for a reason: it combines strong steam output with quick readiness and a more generous 1-litre tank. That tank size and the ability to refill while the unit is running make it practical for whole-room floor work and extended bathroom cleaning without constant interruptions.
Key features
In practice you’ll find it removes limescale and grout grime far more effectively than sprays and many household chemicals. The pump and constant-steam design suit tiled floors and bathroom walls especially well. Users praise how quickly it gets to work and the quality of finish, though some report a tendency to expel excess water if left idle or used incorrectly—short bursts and steady motion minimise that.
Practical notes and limitations
If you expect regular, demanding steam cleaning and live in a hard-water area, the SC 3 is an excellent, reliable choice that reduces reliance on chemical cleaners.
H2O HD 5-in-1 Steam Mop & Handheld
You get a genuinely multi-purpose cleaner that handles floors, grout, windows, clothes and fabric. It balances strong steam output with a compact design so you can use it across the house without needing many separate tools.
The H2O HD 5-in-1 is designed for users who want one machine to tackle multiple cleaning jobs. With a 1500W heater and 450ml water tank, it can be used as an upright mop, a handheld steam wand for grout and ovens, a clothes steamer and for carpet refresher jobs using the carpet glider.
Key features
The machine’s strength is flexibility: you can switch quickly from mopping hard floors to steaming curtains or mattresses. For mattress and carpet work, use the handheld or carpet tool and move in overlapping passes; that approach reduces the risk of over-wetting and gives better stain loosening. Users report it is particularly useful for pet owners and multi-surface homes where buying multiple appliances would be inconvenient.
Practical considerations
Overall, the H2O HD is a strong all-rounder if you want genuine multi-surface capability without stepping up to a specialist machine.
Vax Steam Fresh Total Home Cleaner
You get a flexible steam system that converts between floor and handheld modes, useful across rooms. It balances power and attachments for everyday steam cleaning without being overly complex to use.
The Vax Steam Fresh Total Home Cleaner is aimed at households that want one machine for floors, ovens, bathrooms and spot cleaning. You can switch between upright steam mop use and a detachable handheld unit, which makes it useful for mattress and carpet freshening as well as hard-floor tasks.
Key features
You benefit from a machine that feels flexible in everyday cleaning. The detergent chamber means you can add a mild cleaning solution on tougher greasy areas (oven, hob) while keeping water-only steam for mattresses and upholstery to avoid residues. Users often report it removes mould from grout and lifts stubborn marks from kitchen floors.
Practical limitations and tips
The Vax is a good middle-ground machine if you want one device to cover multiple tasks. If you regularly steam large areas of carpet or a whole house of hard floors, a larger-capacity cylinder model will reduce interruptions, but for mixed domestic use this is a practical, well-equipped choice.
BISSELL SpotClean ProHeat Portable Spot Cleaner
You get a compact, focused spot cleaner for carpets, stairs, car interiors and upholstery. It’s designed to tackle stains with HeatWave technology and specialised pet attachments that keep messes from passing into the machine.
The BISSELL SpotClean ProHeat is a portable spot cleaner designed for targeted stain removal rather than whole-room shampooing. It’s useful for carpets, upholstery, stairs and cars where you need to lift stains quickly and effectively; the HeatWave system helps keep the cleaning solution warm at the correct temperature for better results.
Key features
This cleaner is especially helpful if you have pets or children and need to treat accidents quickly. It gets into upholstery creases and carpet fibres better than manual stain treatments, and many users find it restores appearance without leaving a crusty residue. The machine’s portability also makes it ideal for cleaning car interiors or awkward stairs that a full-size carpet cleaner can’t access.
Practical tips and limitations
If your main need is targeted stain removal and upholstery care, this machine is a strong, space-saving addition to your cleaning kit.
Shark Klik n' Flip Steam Mop
You get a smartly designed floor-focused mop that heats fast and cleans sealed hard floors effectively. The double-sided Klik n' Flip head is useful for getting through more floor area between pad changes.
The Shark Klik n' Flip is a purpose-built steam mop for sealed hard floors such as hardwood, tile, vinyl and stone. Its signature feature is the reversible mop head: you flip it to double the pad life between washes, which is helpful on large tiled kitchen floors where you want consistent steam coverage.
Key features
For day-to-day floor maintenance it’s quick and effective: you’ll notice floors dry faster than with a wet mop and sticky residues often lift cleanly. The design rewards methodical use—moving more slowly and letting steam work improves results. Many owners buy spare pads to keep cleaning without pausing for washes.
Practical considerations
This is a strong choice if sealed floors are your priority and you prefer a lightweight, simple-to-use machine rather than a multi-tool steamer.
Beldray Titanium 14-in-1 Steam Mop
You get a small, affordable steamer that converts to a handheld unit and reaches awkward places with a flexi-hinge. It’s best for quick spot jobs, small rooms and occasional mattress or upholstery freshening.
The Beldray Titanium 14-in-1 is a budget friendly steam mop designed for people who want versatility without a high price tag. It converts into a handheld steamer and has a flexi-hinge to reach under furniture and into awkward corners, which is handy when you want to treat stains on mattresses or spot-clean carpets.
Key features
This steamer suits quick cleans and occasional deep spot work rather than long continuous sessions. You can expect chemical-free sanitising on sealed floors and fabric surfaces; however you will need to work slower on heavy stains and allow time for steam to penetrate thicker fabrics. Several users note that extra mop pads or slightly different pad sizes improve performance.
Practical tips and limitations
If you need a low-cost multi-tool that does many jobs reasonably well, this is a sensible buy. For heavy, frequent carpet cleaning or whole-house steaming you will want a larger, higher-capacity model.
Tower TSM12 12-in-1 Steam Mop
You get a generously accessorised, low-cost steamer that handles a range of household tasks. Reliability can be mixed, so you should expect good occasional use but be cautious about long-term durability.
The Tower TSM12 is an economical option that promises 12 functions in one machine. It includes a detachable handheld unit, three power settings and multiple accessories aimed at floor, grout, oven and fabric tasks. This makes it attractive if you want a single low-cost unit to try steam cleaning on mattresses and carpets.
Key features
In day-to-day use it performs well for short sessions and spot cleaning. Users like the ease of filling and the lightweight nature when moving between rooms. However, there are reports of failures after months of use by some owners, and that can be frustrating if you expect a longer service life.
