01BISSELL Little Green Portable Carpet & Upholstery Cleaner (1400B)
The Bissell Little Green and Hoover CleanSlate are the two names that dominate the portable spot cleaner market. Both spray, scrub, and suction stains from carpet and upholstery — but they approach the job differently.
We compared published specifications and analysed buyer reviews across both brands to identify the real, practical differences that actually matter when you are on your knees cleaning a stain.
Where Hoover CleanSlate wins
Weight and portability
The CleanSlate Plus weighs ~9 lbs versus the Little Green's ~10 lbs. That 1 lb matters less on paper than in practice — the CleanSlate's handle design makes it genuinely easier to carry one-handed up stairs, according to buyer feedback.
Water extraction and drying time
The CleanSlate extracts water more aggressively than the base Little Green. Buyer reviews consistently report upholstery drying in about an hour versus 2–3 hours for the Bissell. This is the CleanSlate's single biggest advantage.
WidePath tool
The 7" WidePath tool covers more surface per pass, making large areas like stair treads and couch cushions faster to clean than the Bissell's narrower 3" tool.
Where Bissell Little Green wins
Ecosystem and model options
Bissell offers the original, ProHeat, Pet Pro, HydroSteam, Mini, and SpotClean Pro — a range that covers every price point and use case. Hoover has three CleanSlate variants. If you want to start basic and upgrade later within the same accessory ecosystem, Bissell is the safer bet.
Pet stain performance (Pet Pro model)
The Bissell Little Green Pet Pro has stronger suction and ships with enzyme-based formula. For recurring pet accidents, it outperforms every CleanSlate model based on aggregated buyer satisfaction data.
Formula variety
Bissell offers more cleaning solution options — general OXY, pet enzyme, and professional formulas. Hoover's formula range is narrower.
Our verdict
General household stains + fast drying: Hoover CleanSlate Plus. The water extraction is genuinely better, the machine is lighter, and the WidePath tool saves time.
Pet owners: Bissell Little Green Pet Pro. The enzyme formula and pet-specific tooling give it a meaningful edge over the CleanSlate Pet.
Budget buyers: The base Bissell Little Green is cheaper than any CleanSlate and does the basics well.

Frequently asked questions
Can I use Bissell formula in a Hoover CleanSlate?
Technically yes — both machines use water-based cleaning solutions in similar dilutions. However, Hoover recommends their own formula, and using third-party solutions may void the warranty. In practice, many buyers report using Bissell formula in their CleanSlate without issues.
Which is quieter?
Both are similar — typical vacuum-level noise. Neither brand publishes decibel ratings, and buyer reviews do not consistently favour one over the other on noise.
Which brand has better customer support?
Bissell has a larger support infrastructure with more replacement parts readily available on Amazon. Hoover support is adequate but buyers report slightly longer wait times for parts.
