A portable upholstery cleaner can remove a mattress stain and pull dirty solution back out, but it can also make a mattress too wet if you treat it like carpet. The best machine for this job is not the one that sprays the most water. It is the one that gives you controlled application, useful suction, a tool that fits the stain, and an easy way to clean and dry the machine afterward.
The useful test for upholstery-cleaner results on mattresses is how well the materials, fit, construction, and upkeep match the household.
Before using any extractor, check the mattress care instructions and warranty. Some mattresses allow only light spot cleaning. If wet extraction is allowed, use restrained solution and make several suction-only passes after the visible stain is gone.
When comparing using upholstery cleaner on a mattress, prioritize relevant dimensions, durable construction, manageable care, and the intended role.
The Shark StainStriker leads this group for its useful sub-nine-pound tool kit and strong suction. The original BISSELL Little Green is the familiar all-purpose alternative, while Hoover CleanSlate Plus is better when a wide mattress-top tool and a narrow edge tool both matter.
When comparing professional mattress-cleaning equipment, prioritize relevant dimensions, durable construction, manageable care, and the intended role.

Our Six Picks
1 / 6
Shark StainStriker
Weight
8.5 lb
Tools
3.5 in stain, pet mess, crevice
Cleaning system
Dual formula
Use
Carpet, upholstery, area rugs
The Shark StainStriker is the best overall mattress extractor because it combines low weight with a genuinely useful set of tools. At 8.5 pounds, it is easier to carry and reposition than the 13.2-pound SpotClean Pet Pro, and it includes a 3.5-inch stain tool, a pet-mess tool, and a crevice tool.
Those attachments match mattress work well. Use the small stain tool for a contained spill, the crevice tool around piping and seams, and the pet-mess tool when an organic accident needs more focused extraction. The machine mixes its deep-clean and Oxy solutions during use, while suction pulls loosened liquid back into the dirty tank.
Suction is effective for repeated recovery passes, the tanks rinse easily, and the included formula can last through months of occasional spot use. The hose remains the long-term wear point to watch, as it is on many portable cleaners. After every mattress job, rinse the tools and hose, empty both tanks, and let every wet part dry open.
Why It Works
- 8.5-pound weight is easy to move around a bed.
- Three distinct tools cover broad stains, pet messes, and seams.
- Suction is strong enough for repeated dry extraction passes.
- Tanks and tools are straightforward to rinse after use.
What To Keep In Mind
- Do not keep spraying once the stain is wet enough for the cleaner to work.
- Inspect the hose for cracks as the machine ages.
- Small portable tanks are better for spots than an entire soaked mattress surface.
- Use only compatible cleaning solution and follow mattress-care limits.

BISSELL Little Green Portable Cleaner
Weight
9.7 lb
Workflow
Spray, scrub, suction
Tools
Specialty upholstery tools
Use
Upholstery, carpet, small messes
The original Little Green is the easy all-purpose choice. Its 9.7-pound body is built around a simple spray, scrub, and suction routine, and it can move from a mattress spot to a sofa, rug, car seat, or patio cushion without requiring a full-size carpet cleaner.
For mattress use, the most encouraging characteristic is that it does not have to leave the surface drenched. Careful solution control can leave fabric only moderately damp, though a heavily treated area can still take several hours to dry. That variation is a reminder to control your own spray time.
First-use setup can be confusing. The tank can leak before it is installed, and the tool instructions could be clearer. Once assembled, however, the machine is a practical spot cleaner with enough suction to pull dark residue from old upholstery and fabric stains.
Why It Works
- Straightforward spray, scrub, and suction sequence.
- 9.7-pound body is portable enough for bedroom use.
- Useful beyond mattresses, which makes storage easier to justify.
- Can leave fabric only moderately damp when solution is used carefully.
What To Keep In Mind
- Do not assume the mattress will dry quickly if you overspray.
- Make several suction-only passes after cleaning.
- Check tank seating if you see leakage during setup.
- Rinse and dry tools before storage.

Hoover CleanSlate Plus
Weight
9.4 lb
Clean tank
40 oz
Tools
7 in WidePath and TightSpot
Use
Carpet and upholstery
Hoover CleanSlate Plus is the best choice when you want one tool for a broad flat mattress area and another for edges. The seven-inch WidePath head covers much more surface than a three- or four-inch spot tool, while the TightSpot tool reaches seams and narrow spaces.
The 40-ounce clean-solution tank gives you more working room than very small portable units. On a mattress, that capacity should be treated as convenience rather than permission to use the whole tank. Spray sparingly, then use the wide head for repeated recovery passes.
At 9.4 pounds, the machine is still portable. Suction is solid for upholstery and car cleaning, and cleanup is generally easy. Long-term leak and sprayer concerns exist, so inspect connections before starting near a mattress where an unexpected drip can add moisture you did not plan for.
Why It Works
- Seven-inch head speeds up broad mattress-top cleaning.
- TightSpot tool reaches edges, piping, and seams.
- 40-ounce clean tank reduces refills on multi-surface jobs.
- Weight remains reasonable for carrying between rooms.
What To Keep In Mind
- A large clean tank does not mean a mattress should be heavily saturated.
- Watch hoses, fittings, and sprayer performance over time.
- Use repeated dry passes after the final wet pass.
- Allow the mattress to dry uncovered before adding bedding.

BISSELL SpotClean Pet Pro 2458
Weight
13.2 lb
Tank
3/4 gallon
Hose
4 ft
Tool
3 in pet stain trapper
Power
5.7 amps
The SpotClean Pet Pro is the capacity specialist. Its three-quarter-gallon tank is the largest clearly supported tank in this group, and a four-foot hose lets the 13.2-pound machine stay on the floor while you work on the bed. A three-inch pet stain trapper gives you focused control over small organic messes.
The larger tank is useful when you are cleaning several upholstered items in one session or tackling a mattress plus surrounding pet furniture. Strong suction and good set-in-stain performance are the main strengths, and the machine is relatively simple to clean after use when you rinse it promptly.
Weight is the obvious compromise. At 13.2 pounds, this is the least convenient model to carry upstairs or reposition around a tight bed. Tool variety is also narrower than Shark's. Choose it when tank capacity and extraction matter more than a large attachment kit.
Why It Works
- Three-quarter-gallon tank reduces refill stops.
- Four-foot hose lets the machine remain on the floor.
- Three-inch pet tool gives precise spot control.
- Strong suction supports moisture recovery.
What To Keep In Mind
- 13.2-pound weight is the heaviest here.
- Fewer attachment roles than Shark or Hoover.
- Handles and connections can leak if wear develops.
- Large capacity should not encourage over-wetting a mattress.
5 / 6
BISSELL Little Green Mini
Weight
7 lb
Tool
4 in Tough Stain Tool
Maintenance
HydroRinse hose tool
Use
Upholstery, pet beds, car interiors
The Little Green Mini is the easiest model to carry and store. It weighs seven pounds and uses a four-inch Tough Stain Tool with a removable lens. The HydroRinse accessory lets you flush the hose after dirty-water extraction, which is especially useful after pet or body-fluid cleanup.
That compact setup suits one or two fresh mattress spots better than a whole-mattress job. The small footprint simplifies storage and cleanup, and fresh stains respond well when treated promptly. The small tanks mean more filling and emptying if you expand the job to a sofa or several areas.
One workflow quirk is that the spray operates only while the vacuum is running. That is not a major problem, but it changes how you pace the wet pass. Use short bursts and move quickly into suction-only recovery.
Why It Works
- Seven pounds is the lightest weight here.
- Four-inch tool is easy to control over a mattress spot.
- Removable lens gives access to trapped debris.
- HydroRinse helps flush residue from the hose.
What To Keep In Mind
- Small tanks suit spot work better than large wet areas.
- Spray requires the vacuum to be running.
- Excess solution can leave soap residue after drying.
- Let tanks and hose dry open before storage.

Dirt Devil Portable Spot Cleaner
Weight
10.33 lb
Tank
19 oz
Tools
4 in stain, 2-in-1 pet
Hose
Kink-free
Dirt Devil lands in the middle ground between a tiny spot machine and a larger extractor. It weighs 10.33 pounds, uses a 19-ounce tank, and includes a four-inch stain head plus a two-in-one pet tool. The kink-free hose gives useful reach without making you drag the body across the floor constantly.
Suction is strong enough for upholstery and small carpet areas, and the four-inch head is a sensible size for a mattress stain. The pet tool gives it a useful second role if animals share the bed or furniture.
The 19-ounce tank is the limiting factor. Dirty water can fill quickly on a larger cleanup, which means more stops. That is not necessarily bad on a mattress—smaller batches can discourage oversaturation—but it makes the machine less convenient for big upholstery jobs.
Why It Works
- Four-inch head gives good spot control.
- Two-in-one pet tool adds a second useful role.
- Kink-free hose supports comfortable reach.
- Suction is useful for small upholstery jobs.
What To Keep In Mind
- The 19-ounce tank fills quickly on larger areas.
- More emptying is required than with the SpotClean Pet Pro.
- Keep all parts dry before storing the machine.
- Use short wet passes and longer recovery passes on mattresses.
How to Use a Portable Upholstery Cleaner on a Mattress
Check the mattress instructions first
Do not assume wet extraction is allowed. Some mattress warranties restrict cleaning methods, and certain covers are meant only for very light spot treatment.
If the cover is removable and machine washable, cleaning it separately is often easier than introducing water into the mattress itself.
Vacuum dry debris first
Remove sheets and vacuum dust, hair, crumbs, and lint before spraying solution. Wet hair and debris can clog a small upholstery tool and turn into residue in the hose.
If pets use the bed, pay extra attention to seams and piping.
Use the smallest useful tool
A three- or four-inch head is easier to control on a small stain. A seven-inch head makes sense only when the affected area is broad and shallow.
Crevice tools are useful around mattress seams, but do not force liquid into deep stitching simply because the nozzle fits there.
Spray sparingly
Make one controlled wet pass. The fabric should be damp enough for the cleaner to contact the stain, not soaked until liquid disappears into foam.
If the stain remains, extract first before deciding whether another wet pass is needed.
Make several dry passes
Release the spray trigger and move slowly over the area with suction only. Repeat until very little water is visible through the tool or entering the dirty tank.
This is the most important mattress-specific step. Water left in foam takes much longer to dry than water left in a thin carpet pile.
Dry the mattress completely
Use fans and open room airflow. Leave bedding off. If the mattress can safely be positioned to improve airflow, expose more than one side.
Do not judge dryness only by touching the top fabric. Press firmly and check for a cool damp feeling from below.
Clean the extractor after every use
Empty the dirty tank immediately. Rinse the tool, lens, hose, and tank using the machine's cleaning accessories where provided.
HydroRinse and similar tools make this easier, but they do not remove the need to air-dry the parts. Leave caps and tanks open until everything is dry.
Frequently Asked Questions
What is the best portable upholstery cleaner for a mattress?
Shark StainStriker is the best overall balance because it weighs 8.5 pounds, offers three useful tools, has strong suction, and is easy to rinse after spot cleaning.
Is a portable carpet cleaner safe for a mattress?
Only when the mattress instructions permit wet spot cleaning. Use very little solution, make repeated suction-only passes, and dry the mattress completely before remaking the bed.
Which cleaner is lightest?
The BISSELL Little Green Mini is the lightest at seven pounds. Its four-inch tool and HydroRinse accessory make it especially convenient for small spots.
Which machine has the biggest tank?
The BISSELL SpotClean Pet Pro has a three-quarter-gallon tank, the largest clearly supported capacity in this group.
Is a wide tool better for a mattress?
A wide tool is faster on a large shallow stain, but a small three- or four-inch tool gives better moisture control on a concentrated spot. Match the head to the stain size.
How many dry passes should I make?
Keep making suction-only passes until the machine is pulling up very little moisture. The exact number depends on how wet the area became and how effective the seal is.
Can I put homemade cleaning solution in the machine?
Use only solution allowed by the machine and mattress instructions. Unapproved mixtures can foam excessively, damage the extractor, leave residue, or react with another cleaner.
