It’s a New Little Green! The Bissell Little Green Pet Pro Portable Carpet Cleaner

Bissell has expanded its popular Little Green product line with the introduction of the Little Green Pet Pro Portable Carpet Cleaner 3909. This new model is designed to offer professional-style cleaning results, specifically aimed at addressing the challenges that come with pet stains and messes.

Differentiating Features

The Little Green Pet Pro has the largest clean and dirty water tanks of the Little Green lineup, including its predecessor, the Bissell Little Green Max Pet, with a clean tank capable of holding up to 64 oz of liquid, and a dirty tank with a 48 oz capacity. This feature minimizes the need for frequent refilling and emptying during extended cleaning sessions.

Additionally, Bissell claims that this new model has the strongest suction among portable carpet cleaners, based on ASTM testing.

Specialized Tools for Pet Messes

The Bissell Little Green Pet Pro comes equipped with several specialized tools to address various cleaning needs:

  • Self-cleaning Tough Stain Tool, which allows users to scrub stains and then flush out the hose to prevent clogging.
  • Pet Hair Removal Tool, which is specifically designed to lift embedded pet hair from upholstery and other soft surfaces.
  • Spraying Crevice Tool is included for reaching tight spaces, making the cleaner adaptable for use in a variety of areas around the home and even in vehicles.

Portable Design and User Convenience

The Little Green Pet Pro is designed to be portable and easy to use. It features a 5-foot hose for hard-to-reach areas and a 15-foot power cord to allow for greater mobility during cleaning. At 13 lbs, it’s lightweight enough for quick transport and storage, despite its large tank capacity. This model also features a quieter motor, claimed to be 50% quieter than previous Pro models.
