BISSELL Little Green Pet Pro 3909 vs 1400B: Choose by Pet Tools, Tank Capacity, and Portability
The 3909 is the feature-fit choice for recurring pet messes and fewer refills; the 1400B is the lighter, lower-offer choice for basic spot cleaning. The available evidence does not establish an overall cleaning-performance winner.

The buying question
Does the 3909's pet tool set and larger tanks justify its extra weight and current offer over the basic 1400B workflow?
The 3909 adds a pet-hair tool, larger published tank capacities and a longer hose; the 1400B is lighter and had the lower dated offer while retaining a basic spot-cleaning tool set.
Quick verdict
Choose BISSELL Little Green Pet Pro Portable Carpet Cleaner, 3909 (ASIN B0CW87SGMM) if
- You regularly remove pet hair or pet stains and will use the dedicated pet-hair tool.
- You value the 64 oz clean tank, 48 oz dirty tank and 5 ft hose for local jobs.
Choose BISSELL Little Green Multi-Purpose Portable Carpet Cleaner, 1400B (ASIN B0016HF5GK) if
- You want the lighter 9.65 lb machine for occasional spills and upholstery touch-ups.
- The 1400B's 3-inch stain tool, crevice tool and HydroRinse workflow cover your needs at the lower dated offer.
When the recommendation changes
- A current seller, color or bundle changes the exact included tools or formula.
- A bilateral controlled test establishes a material cleaning or suction difference.
- The buyer needs whole-room carpet cleaning rather than portable spot treatment.
The differences that matter
Exact Us Variant And Identity
What this changes: The guidance applies to these two exact US model and ASIN assignments; confirm seller, color and included package before purchase.[1, 2]
Spot Cleaning Scope
BISSELL Little Green Pet Pro Portable Carpet Cleaner, 3909 (ASIN B0CW87SGMM)
BISSELL positions the 3909 for spots and stains on carpets, upholstery and auto interiors, with a pet-oriented package.[3]
BISSELL Little Green Multi-Purpose Portable Carpet Cleaner, 1400B (ASIN B0016HF5GK)
BISSELL positions the 1400B for carpet, upholstery, area rugs, furniture, auto interiors and pet messes; an exact-model Reviewed test found it useful for spot upholstery, dirty rugs and couches but not large surfaces.[4, 6]
What this changes: Both are positioned as portable cleaners for localized spills and stains. The 1400B independent review did not find it suitable for large surfaces; no comparable full-room test of the 3909 was found, so neither a whole-room winner nor an overall cleaning-performance winner is established.[3, 4, 6]
Pet Tools And Included Attachments
BISSELL Little Green Pet Pro Portable Carpet Cleaner, 3909 (ASIN B0CW87SGMM)
The 3909 includes a Specialized Pet Hair Removal Tool, self-cleaning Tough Stain Tool, Spraying Crevice Tool and an 8 oz PET PRO OXY trial formula.[3]
What this changes: The 3909 has the clearer feature fit for recurring pet hair; the 1400B still covers ordinary spot jobs with a smaller basic tool set. Included formula and tools should be rechecked on the live listing.[3, 4]
Tank Capacity And Refill Burden
BISSELL Little Green Pet Pro Portable Carpet Cleaner, 3909 (ASIN B0CW87SGMM)
BISSELL lists the 3909 with a 64 oz clean-water tank and 48 oz dirty-water tank.[3]
What this changes: The published capacities give the 3909 more room before refilling or emptying, which fits repeated local jobs. They do not prove better extraction or less total maintenance.[3, 5]
Hose Reach
BISSELL Little Green Pet Pro Portable Carpet Cleaner, 3909 (ASIN B0CW87SGMM)
The exact 3909 page lists a 5-foot hose.[3]
What this changes: The 3909 has the longer published reach, but the conflicting 1400B figures mean buyers should confirm the exact page or package if reach is decisive.[3, 4, 5]
Portability And Storage
BISSELL Little Green Pet Pro Portable Carpet Cleaner, 3909 (ASIN B0CW87SGMM)
The 3909 is listed at 11 lb and has a carry handle, 15-foot cord and 5-foot hose.[3]
What this changes: The 1400B is the lighter carry choice; the 3909's extra weight buys a pet-oriented package and larger published tanks rather than easier storage.[3, 4]
Maintenance And Drying Workflow
What this changes: Both need owner care and drying. The 1400B review adds practical cautions, but no bilateral long-term evidence supports a maintenance or reliability winner.[7, 8, 6]
Current Offer Value

BISSELL Little Green Multi-Purpose Portable Carpet Cleaner, 1400B (ASIN B0016HF5GK)
Pickoryx recorded the exact 1400B ASIN as IN_STOCK at 2026-09-25T19:01:29.269Z; the amount is dynamic and kept out of stable editorial prose.[2]
What this changes: The dated observation makes the 1400B the lower-offer fit. It is dynamic, short-window data and does not establish a historic low or purchase timing.[1, 2]
Best for your routine
Recurring pet hair and pet-stain jobs
Best fit: BISSELL Little Green Pet Pro Portable Carpet Cleaner, 3909 (ASIN B0CW87SGMM)
Based on listed features, not comparative testing.
The 3909's dedicated pet-hair tool and pet-oriented package are the clearer feature fit; this does not prove better measured extraction.
Fewer refills during repeated local jobs
Best fit: BISSELL Little Green Pet Pro Portable Carpet Cleaner, 3909 (ASIN B0CW87SGMM)
Based on listed features, not comparative testing.
The 3909 publishes a 64 oz clean tank and 48 oz dirty tank versus the 1400B family's 48 oz clean and 45 oz dirty figures.
Lowest carry weight
Best fit: BISSELL Little Green Multi-Purpose Portable Carpet Cleaner, 1400B (ASIN B0016HF5GK)
Based on listed features, not comparative testing.
The 1400B is listed at 9.65 lb versus the 3909 at 11 lb.
Basic occasional spot cleaning
Best fit: BISSELL Little Green Multi-Purpose Portable Carpet Cleaner, 1400B (ASIN B0016HF5GK)
Based on listed features, not comparative testing.
The lighter 1400B covers common upholstery, rug, carpet and auto-interior spot jobs with a basic tool set and had the lower dated offer.
Longest published hose reach
Best fit: BISSELL Little Green Pet Pro Portable Carpet Cleaner, 3909 (ASIN B0CW87SGMM)
Based on listed features, not comparative testing.
The 3909 lists 5 feet; the 1400B is listed as 4 feet in its specification and family guide, although BISSELL's introductory copy says 4.5 feet.
What the evidence cannot decide
- Overall stain-removal performance: No controlled bilateral exact-model test of the 3909 and 1400B was found, and the available independent review tests only the 1400B.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
At the dated observations, the 3909 cost more than the 1400B. That premium is easier to justify when recurring pet messes, its dedicated pet-hair tool, larger tanks and longer hose will be used; the 1400B is the value fit for lighter occasional work.
The available offer history is short, so it is insufficient to support a definite Buy Now or Wait timing recommendation. Recheck both exact ASINs, sellers and package contents before purchase.
Is the upgrade worth it?
Worth considering if
- Recurring pet hair or biological messes
- Repeated local jobs where fewer refills and more reach matter
Skip the upgrade if
- You clean occasional small spills and prioritize lower carry weight
- You need whole-room carpet cleaning
- You require bilateral measured performance evidence
Limitations
- No hands-on testing was performed.
- No exact bilateral independent test of the 3909 and 1400B was found; overall cleaning performance remains unresolved.
- The 3909 strongest-suction statement is a manufacturer comparative claim, not independent measurement.
- BISSELL publishes conflicting 1400B hose lengths: 4 feet in specifications/family comparison and 4.5 feet in introductory copy.
- The 1400B product page lists its clean tank but not its dirty tank; the 45 oz dirty figure comes from BISSELL's exact 1400B family row.
- Current offers are short-window observations and do not support a historic low or Buy Now/Wait timing call.
- BISSELL positions both as portable cleaners for localized jobs; the 1400B review says it is not good for large surfaces, and no comparable full-room test of the 3909 was found.
Questions shoppers ask
Is the 3909 worth the upgrade over the 1400B?
It is the feature-fit upgrade for recurring pet messes, the dedicated pet-hair tool, larger published tanks and longer hose. The 1400B is the better fit when lower weight and occasional spot cleaning matter more; no bilateral performance premium is proven.
Which Little Green is lighter to carry?
The 1400B is listed at 9.65 lb, versus 11 lb for the 3909.
Which one is better for pet hair?
The 3909 has the clearer package fit because BISSELL includes a Specialized Pet Hair Removal Tool. For either machine, dry vacuum loose hair first; an exact-model 1400B review reports brush-head clogging from pet hair.
Do these replace a full-size carpet cleaner?
No conclusion here supports that use. Both are portable spot cleaners for localized carpet, upholstery, rug, furniture and auto-interior jobs, and the independent 1400B review found it unsuitable for large surfaces.
Which one needs fewer tank refills?
The 3909 publishes the larger capacities: 64 oz clean and 48 oz dirty versus the 1400B family's 48 oz clean and 45 oz dirty figures. This speaks to capacity, not cleaning effectiveness.
Methodology and sources
Compared only exact-model package, attachment, tank, hose, weight, workflow and offer facts. Manufacturer claims are labeled as such; the 1400B independent review is not generalized to 3909 and no unsupported overall performance winner is assigned.
Product identity and availability were checked against the listed US offers. Feature and use-case conclusions are drawn from the cited BISSELL documents and the 1400B review; neither cleaner was tested for this article.
