Quick Answer: The best carpet shampooer for most homes in 2026 is the Hoover SmartWash+ — its automatic spray system makes deep cleaning nearly foolproof and it removes stains as well as pricier machines. For the deepest clean on heavily soiled or large-area carpet, step up to the pro-grade Bissell Big Green or a Rug Doctor Deep Carpet Cleaner. Pet owners should look at the Bissell ProHeat 2X Revolution Pet Pro.

1. Hoover SmartWash+ — Best Overall Shampooer
Hoover SmartWash+ Automatic Carpet Cleaner
- Automatic triggerless spray: push to wash, pull to dry — no dials to fiddle with.
- Matches the Bissell ProHeat on stain removal for around $100 less.
- Large tanks and wide path clear whole rooms quickly.
- Full-size and heavy — a whole-house machine, not a spot tool.
The SmartWash+ is the shampooer we’d put in most homes. Its automatic spray removes the guesswork of how much solution to lay down, and it cleans as effectively as machines costing more. It’s also the top pick in our overall best carpet cleaner guide.
2. Bissell ProHeat 2X Revolution Pet Pro — Best for Pets
Bissell ProHeat 2X Revolution Pet Pro
- CleanShot pretreater and pet upholstery tool built for accidents and hair.
- Dual counter-rotating DirtLifter brushes lift embedded dirt from high-traffic zones.
- HeatWave and Express Clean mode target a ~30-minute dry time.
- Costs more than the SmartWash, but earns it in pet homes.
If pets share your carpet, the ProHeat 2X Revolution Pet Pro is the shampooer to get. The onboard pretreater and specialized tools make it the best-equipped machine for hair, accidents, and odor. See our full best carpet cleaner for pets breakdown for more.
3. Bissell Big Green — Best Deep Clean
Bissell Big Green Machine
- Pro-grade power that rivals rental machines for heavily soiled carpet.
- Big tanks and wide brushroll clean large areas with fewer passes.
- Owning it beats repeated rentals if you deep clean often.
- Heavy and bulky — this is a serious, occasional-use machine.
The Big Green is the machine to buy when you want rental-grade cleaning without the rental. Its aggressive brushroll and big tanks handle deeply soiled carpet that trips up lighter uprights. It’s heavy, but for big homes and heavy jobs the results justify the bulk.
4. Rug Doctor Deep Carpet Cleaner — Best for Heavy Soil
Rug Doctor Deep Carpet Cleaner
- Vibrating brush and strong extraction lift ground-in dirt from dense carpet.
- The name behind most rental machines — built for tough, occasional deep cleans.
- Owning one pays off fast versus $40-$50 rentals plus solution.
- Heavier and pricier than a standard home upright.
If you’ve ever rented a Rug Doctor from the grocery store, you know the aggressive vibrating-brush deep clean it delivers. Buying the home version makes sense if you deep clean more than a couple of times a year — the machine pays for itself against repeated rental fees, and it’s always ready when you need it.
How to choose a carpet shampooer
- Cleaning power vs. weight. Pro-grade machines (Big Green, Rug Doctor) clean deepest but weigh the most. Standard uprights are lighter and easier to store.
- Automatic vs. manual spray. Auto-spray (Hoover SmartWash) is more foolproof; manual gives control but risks over-wetting.
- Tank size. Bigger tanks mean fewer refills on large homes.
- Dry time. Heated drying and a dry-only pass get you back on the carpet in hours, not the whole day.
- Buy vs. rent. Deep clean twice a year or more? Owning beats renting quickly.
The bottom line
For most homes the Hoover SmartWash+ is the best carpet shampooer — foolproof and effective. Pet owners should choose the Bissell ProHeat 2X Revolution Pet Pro, and anyone facing heavily soiled or large-area carpet should invest in the Bissell Big Green or a Rug Doctor Deep Carpet Cleaner. On a tight budget, the Hoover PowerDash Pet Advanced still gets carpets genuinely clean.
