A pet accident rarely happens somewhere convenient: it is the hallway rug, the back seat of the car or the third stair. Dragging out a full-size carpet cleaner for one patch is a chore, and that gap is what small portable cleaners such as the BISSELL Little Green Max Pet, model 3860B, are made for.
This is a corded spot cleaner, not a machine for deep cleaning a whole house. Amazon Canada lists it at C$119 at the time of writing, as checked on 2026-11-12. Here is what BISSELL says it does, what it leaves out and who it suits.
What is the BISSELL Little Green Max Pet 3860B?
It is a compact, corded carpet and upholstery cleaner in black with lime accents, with a carry handle on top. According to BISSELL’s Canadian and US product pages, the main specs are:
- Clean tank: 32 oz
- Dirty tank: 32 oz, kept separate from the clean water
- Power cord: 15 feet
- Hose: 4.8 feet
- Weight: 8.2 lbs
- Tools: Specialized Pet Hair Removal Tool and Self Cleaning Tough Stain Tool
- Warranty: Canada 3 Year Limited Warranty, as stated on the Canadian page
The 3860B code is the Canadian model number. BISSELL’s US site lists the same machine as model 3860 with identical cord, hose, tank and weight figures.
What can it clean?
BISSELL lists carpet, area rugs, low pile carpet, stairs, pet beds, auto and garage interiors, and upholstery and fabric. In practice that covers the places pet messes tend to land: the living room rug, the stairs, the dog bed and the car seats.
The Self Cleaning Tough Stain Tool flushes residue after it suctions. The pet hair tool is meant for the hair that gets caught in fabric. BISSELL also says suction is 30% stronger than the Shark StainStriker, measured by an ASTM F558 air power test, and that the machine was tested for 500+ hours in labs and homes. Those are the maker’s claims, and we have not verified them.
What formula does it use?
BISSELL recommends its Triple Action PET PRO OXY Spot & Stain formula with Urine Eliminator and StainProtect Technology. The page also says the machine has no internal heater and recommends warm tap water, not boiling, in the clean tank.
Prices
- Amazon Canada (amazon.ca), Canadian dollars: C$119 at the time of writing, checked on 2026-11-12. Prices can change at any time.
- Maker’s list price: BISSELL’s Canadian page shows a price but does not name a currency beside it, so we do not quote it here. We also have no verified sale or earlier price data, so this is a listing price only, not a discount.
Who does the BISSELL Little Green Max Pet suit?
Pet owners with carpets, rugs and stairs. The 4.8 foot hose and two 32 oz tanks suit fresh accidents and small patches. The trade off is size: with 32 oz of clean water, bigger jobs mean stopping to refill and empty.
Drivers who carry a dog or cat. At 8.2 lbs with a carry handle, it can be taken to the garage or driveway, and BISSELL lists auto interiors as a surface. You will need a power outlet within reach, since the 15 foot cord is the only power source.
Households that want one small machine for spots and upholstery. BISSELL describes the design as lightweight and compact. Note that the cleaning formula may need to be bought separately, since the page does not say one is included.
Anyone who needs whole-room or whole-house deep cleaning. Skip it. A portable cleaner of this size is for spots and small areas, and large expanses of carpet will take many tank refills.
What is still unknown?
BISSELL’s pages do not give the unit’s dimensions, and the Canadian page does not say whether a bottle of formula comes in the box. We have not tested the machine, and we cannot confirm how well it removes old or set-in stains.
Before ordering, check the amazon.ca listing for the exact model code 3860B and what is included, then compare the price with BISSELL’s own page.
