01BISSELL Little Green Portable Carpet & Upholstery Cleaner (1400B)
The Bissell Little Green (1400B) and the Little Green Pet Pro (2891) share the same DNA — portable spot cleaners that spray, scrub, and suction stains from carpet and upholstery. The difference is what happens when the stain comes from a pet.
We analysed hundreds of buyer reviews for both machines and compared the published specs head-to-head. Here is where the Pet Pro earns its price premium, and where the base Little Green is genuinely enough.
The three things the Pet Pro does better
1. Stronger suction
The Pet Pro 2891 has noticeably stronger suction than the 1400B. Based on buyer reviews, this translates to two practical benefits: deeper stain extraction (the machine pulls more dirty water out of the fibre) and faster drying times (roughly 1–2 hours versus 2–3 for the standard model).
2. Dedicated pet stain tool
The Pet Pro ships with a specialised pet stain tool that concentrates suction and scrubbing on the small, dense stains pet accidents typically leave. The base Little Green's 3" Tough Stain Tool works, but the pet tool is shaped and sized for the job.
3. Enzyme-based formula
The included PET PRO OXY Urine Eliminator uses enzymes to break down the proteins in urine and vomit. This is the difference between masking a pet stain and actually eliminating it — enzymes prevent the odour that causes pets to re-mark the same spot.
Where the base Little Green is enough
No-pet households: If your stains are coffee, wine, food, and mud, the enzyme formula is unnecessary and the standard suction handles these fine.
Car detailing: Both models work well on fabric car interiors. The base model's specialty automotive tools are actually the better kit for vehicles.
Tight budgets: At ~$123 vs ~$140, the base model saves ~$20. For occasional use on fresh spills, that savings is rational.
Our verdict
If you have pets: The Pet Pro is worth every dollar of the premium. The suction and enzyme formula difference is not marketing — it is measurable in buyer outcomes.
If you don't have pets: The base Little Green is the smarter buy. You are paying for pet-specific features you will never use.

Frequently asked questions
Can I use the Pet Pro formula in the regular Little Green?
Yes. All Bissell portable cleaner formulas work across the full Little Green and SpotClean range. You can buy the PET PRO OXY formula separately and use it in the 1400B — you just won't get the stronger suction.
Is the Pet Pro louder?
Slightly. The stronger motor produces marginally more noise, but buyers consistently describe both as "vacuum-level" — not uncomfortably loud for home use.
Which one is better for stairs?
The base Little Green at ~10 lbs is lighter and easier to carry on stairs. The Pet Pro at 13 lbs is heavier but still manageable for most people. Both include tools suitable for stair cleaning.
