Observed prices grouped into tiers, with the complaint themes owners actually report at each level. Prices are point-in-time snapshots.
What the data supports
Bagged docks add consumable costs; bagless docks trade that for more frequent hands-on emptying.
Complaint themes are directional — only a small share of owner comments record a complaint at all.

Three-year cost calculator
Pick a fully rated model to see the observed purchase price plus estimated consumables over three years of ownership.
Assumptions: $30/year for filters and brushes on every model, plus $15/year for bags on bagged self-empty docks, plus $20/year for pads on mopping models. Estimates are directional; the purchase price is a point-in-time snapshot, not a live quote.
Estimated cumulative cost of ownership — ZenVacuum estimate, not a retailer quote
