Are portable spot cleaners actually worth it, or just a glorified spray bottle?

Specialist communities are split. In high-trust auto-detailing discussion threads, owners describe units like the Bissell Little Green as a genuinely useful hot-water extractor for fresh messes, car interiors and small spills. Skeptics in cleaning-focused subreddits counter that these machines have weak suction and limited tank size, so they are best understood as spot cleaners for fresh stains rather than replacements for a full-size carpet extractor.
