Wet/Dry Vacuum Companies methodology
How Wet/Dry Vacuum Companies are qualified and scored using frozen weights, evidence rules, confidence, tie handling, and immutable versions.
Last verified 2026-08-20
Scope
Companies offering current wet/dry vacuums for U.S. consumer or prosumer garage, workshop, vehicle, renovation, and light-jobsite cleanup. The company is ranked using documented representative models across compact, mainstream, large-capacity, and cordless segments where available.
Help U.S. buyers choose a wet/dry vacuum brand with strong real cleanup capability, filtration, durability, usability, support, and product-range fit without treating peak horsepower as a direct performance measure.
Criteria and weights
Evidence standard
Material score inputs must resolve through a public claim and evidence record to an admissible source. Primary documentation supports specifications and policies; credible independent evidence is used for performance or experiential claims when available. AI output and search snippets are not ranking evidence.
Missing and conflicting evidence
Missing evidence is never guessed or silently reweighted. A predeclared category rule may handle a verified absence; otherwise the score remains incomplete. Conflicting source evidence stays visible, can reduce confidence, and blocks an input when unresolved.
Coverage and confidence
Evidence coverage measures how much of the frozen rubric has admissible support. Confidence reflects source strength, freshness, corroboration, and source-conflict status. Neither measure adds points to the organic score.
Deterministic scoring, rounding, and ties
Scores use the frozen weights above and full-precision deterministic arithmetic. Public scores use one decimal place, but rank order uses the unrounded value. Remaining ties use competition ranking and are never broken by editorial preference.
Versions and corrections
This page describes Version 1.0 of the methodology for Version 1.0 of this ranking. A material evidence or scoring change creates a successor version; prior published history is not silently overwritten.
The primary public ranking displays at most the Top 10 qualified companies. Complete evaluated results and immutable rank history remain in canonical data; scores are never changed to fill or enter the public list.
Included
- At least one current U.S.-available wet/dry vacuum is documented by the manufacturer or authorized retail owner.
- Representative current models disclose enough capacity, power-source, filtration, usability, or performance information to evaluate every critical rubric position.
Excluded
- Dry-only vacuums, dust extractors with no supported wet pickup configuration, discontinued-only ranges, and brands unavailable to U.S. buyers.
- Marketplaces, generic private-label listings without a stable brand range, and candidates lacking evidence for a critical rubric position.
