Best Portable Carpet Cleaner with Heat

Get the BISSELL Little Green HydroSteam Pet. It's the portable spot cleaner that heats its own water: a built-in flow-through heater and a temperature sensor turn the water and cleaning solution into steam. A portable is built for smaller jobs rather than a whole room at once: isolated stains, pet accidents, stairs, upholstery, rugs and car interiors. The HydroSteam holds 64 oz in the clean tank and 51 oz in the dirty one, and at 13 lb it's easy to lift onto the stairs or into the car.

Is a Heated Carpet Cleaner Worth It

A heated carpet cleaner is worth it when the mess is oily or sticky. BISSELL rates SteamWash up to 50 percent better on oily stains, and in Steam mode upholstery dries in about 25 minutes, quick enough that a couch goes back into use the same afternoon.

Carpet cleaners are worth it when deep cleaning is a standing job rather than a one-time rescue. A pet or a small child makes it a standing job.

Homes with pets or children

BISSELL recommends deep cleaning carpets every 6 to 12 months, and more often in high traffic rooms or homes with pets and children. A pet or a toddler puts a house in the more-often half of that range, and the accidents don't wait for the calendar. Those are spot jobs, and a machine that heats its own water is the one built to take them on.

If your house cleans on that schedule, get the BISSELL Little Green HydroSteam Pet, a portable spot cleaner.

What Is the Highest-Rated Portable Carpet Cleaner

The Shark StainStriker HairPro is the highest-rated portable carpet cleaner in the class, and the top rated carpet shampooer on the one score that decides it: stain reduction.

On dried grape juice on white carpet it scored 165 against a 145 category average, the best figure recorded for a portable spot cleaner. Owners rate it 4.5 stars across more than 6,000 reviews, against a 4.37 star category average, with about 5 percent one-star reviews where the category runs 7 percent.

It's also the best carpet shampooer for pet urine, because its Deep Clean Pet formula and its Oxy Multiplier stay in separate tanks until the trigger mixes them into an oxy-boosted spray. Four brush attachments ship with it where the category average is two, and one of them, a HairPro extractor tool, funnels collected hair into an internal cage instead of the suction path.

Is There a Carpet Cleaner That Heats the Water

Yes, and it's a portable: the BISSELL Little Green HydroSteam Pet heats its own water, which makes it the best heated carpet cleaner you can carry. Three modes put that heat to work: SteamWash for oily and sticky messes, Steam for refreshing upholstery, grout and tile, and Wash for spills and pet accidents.

The cord length and the tools decide how far it reaches and what it takes on. It runs a 15 ft cord and a 4.8 ft hose, ships with a 5 in Tough Stain Tool and a Multi-Surface Tool, and BISSELL lists auto and garage among its surfaces.

The UWANT B300Pro is the portable to skip if heat is what you came for. It has no heater, its cleaning mode is room temperature water, and warm water up to 50 C is as far as UWANT goes before boiling water damages the machine.

BISSELL draws the same line through its own portables: a ProHeat carpet cleaner uses HeatWave Technology to hold the temperature of the water you poured in, while the HydroSteam, the portable carpet cleaner with heat, combines steam with cleaning solution.

Which Bissell Carpet Cleaners Heat the Water

One BISSELL machine on this page heats water, and the BISSELL ProHeat 2X Revolution Pet Pro is not it. HeatWave Technology holds the temperature of the warm tap water you pour into the tank, using the motor's own heat.

How to use a BISSELL Pro Heat carpet cleaner comes down to the fill: warm tap water in the tank, and HeatWave keeps it there while you clean. The heat comes from your tap, never from the machine.

If you open a BISSELL Revolution ProHeat 2X manual looking for a heater setting, there isn't one: the warm tap water you pour in is the only heat the cleaning gets.

The Big Green Machine does not heat the water either, and BISSELL recommends filling its clean tank with warm tap water. The portable Little Greens without a heater take hot tap water, but not boiling.

Steam Cleaner

A carpet steam cleaner is a hot water extraction machine: hot water and cleaning agent are injected into the carpet fibers, and the lifted soil comes back out with a vacuum.

Hot Water Pressure Washer

A steam pressure washer rental gets you a full-size upright rather than a spot machine, and the models on the rack are the Mighty Pro and the Wide Track: offered at thousands of locations in the United States and Canada on 24 hour or 48 hour terms.

They scrub carpet with a vibrating brush rather than a rotating brush roll, and they carry two large capacity tanks and an adjustable fold-down handle. The upholstery and stair tool add-on brings a 12 ft hose and a 4 in wide tool, which cleans stairs, sofas, upholstered chairs, area rugs and auto interiors.

Rug Doctor states its rental machines are hot water extraction machines, spraying hot water and formula and sucking it back up, which is why the same machines are called steam cleaners and carpet shampooers.

The tool add-on fits either the 24 hour or the 48 hour term at the same cost, and some locations make you choose the 48 hour option when you rent.

For a stain, a stair or a car interior rather than a whole room, the rental upright is more machine than the job needs. Some locations stock a Pro Portable Spot Cleaner for smaller jobs, and the best handheld carpet cleaners are built for that same work.
