Bissell Little Green HydroSteam Portable Carpet Cleaner 3618 — Compact Steam + Pet OXY Formula, 3 Cleaning Modes

The BISSELL Little Green HydroSteam Portable Carpet Cleaner (3618) is a compact deep-cleaner that combines steam, strong suction, and a pet-formulated OXY cleaner to remove set-in stains across carpets, upholstery, tile, and auto interiors.

Designed for homes with pets and active families, this portable machine uses BISSELL’s HydroSteam® Technology to tackle oily, ground-in messes up to 50% better than conventional portable cleaners. It offers three cleaning modes so you can switch between heavy-duty stain removal and gentle refreshes, and it ships with a powerful PET PRO OXY Spot & Stain Urine Eliminator to address pet accidents and help prevent re-soiling.

How does HydroSteam® Technology improve stain removal?

HydroSteam blends targeted steam with concentrated suction and the PET PRO OXY formula to loosen, lift, and extract stubborn, oily, or set-in stains. The combined action breaks down soils molecules so the machine can remove them more effectively than water alone.

• Steam to loosen oily and stuck-on residues
• Powerful suction extracts loosened soil and liquid
• OXY spot formula boosts breakdown of organic and oily stains
• Works across carpets, upholstery and hard surfaces

Which cleaning modes should I use for different messes?

The Little Green HydroSteam has three distinct modes so you can match intensity to the job: SteamWash for heavy, oily soils; Steam for gentle steam cleaning and refreshing fabrics; and Wash for enzyme-based pet accidents. Switching modes helps protect delicate fabrics while still giving maximum performance on tough stains.

• SteamWash: heavy-duty stain penetration and extraction
• Steam: gentle steam refresh and sanitizing action for upholstery
• Wash: enzyme-compatible mode for urine and organic stains
• Mode selection optimizes drying time and fabric safety

What attachments and features make it versatile for home and car?

This model includes a 5" Tough Stain Tool for carpets and stairs plus a Multi-Surface Tool for tile, grout and even sneakers. A dual-tank design separates clean solution from dirty water, and the 64 oz. clean tank capacity reduces refill frequency for larger jobs.

• 5" Tough Stain Tool for concentrated carpet and upholstery work
• Multi-Surface Tool unlocks hard-surface cleaning like tile and sneakers
• Dual tanks: 64 oz. clean tank and easy-to-remove dirty tank for hygiene
• Fast-drying upholstery performance—dries in about 30 minutes

Does this product help with pet stains and odors?

Yes—the cleaner ships with BISSELL PET PRO OXY Spot & Stain Urine Eliminator with StainProtect formula, formulated specifically to remove protein-based stains and reduce the likelihood of re-soiling. Using the Wash mode with the OXY formula gives enzyme and oxygen-powered stain removal while the HydroSteam system extracts residue efficiently.

• Includes PET PRO OXY Spot & Stain formula
• StainProtect technology helps reduce repeat stains
• Enzyme action targets urine and organic soils
• Combined with steam and suction for thorough extraction
