The board ranks 18 robot vacuums from S (best) to F (avoid), last researched 19 Aug 2026, drawing on 543 outlet citations across the board. Placed in the bottom tiers as ones to avoid: Dreame D10 Plus Gen 2, Mova P10 Pro Ultra, Dyson 360 Vis Nav, and 3 others.",

Every run ranks a board of candidates that deliberately includes products buyers cross-shop but should avoid. Placements score on a ranked ladder (LP), and tiers are derived from LP, so no tier is ever assigned by hand.",
