Every category below is a live Value Score tool — assembled from manufacturer specs, normalized to price, and reweightable by you. We don't name a winner. You set what matters; the math ranks it. The formula is published on every page.
13 units scored on suction (Pa), battery runtime, self-empty dock capacity, mopping tier, navigation quality & operating noise — normalized to price.
13 machines scored on machine type, boiler system, PID temp control, steam power, build & footprint — normalized to price.
12 grinders scored on burr type, burr size, stepless adjustment, single-dosing, retention & build — normalized to price.
13 air fryers scored on capacity, wattage, max temperature, one-touch presets, dishwasher-safe basket, footprint & build — normalized to price.
13 makers scored on SCA Golden Cup certification, brew temperature, thermal vs glass carafe, capacity, programmability & build — normalized to price.
12 systems (12,000 BTU) scored on SEER2, HSPF2, low-temp heating floor, indoor noise, warranty & inverter turndown — normalized to price.
13 pumps scored on flow at 10ft of head, max lift, horsepower, switch reliability, warranty & battery backup — normalized to price.
13 stations scored on battery capacity (Wh), continuous output (W), AC recharge time, chemistry (LFP), cycle life & weight — normalized to price.
1. We assemble the data. Every unit's specs pulled from manufacturer sheets and standards bodies — the numbers nobody else bothers to put in one sortable place.
2. You set the weights. Drag sliders for what you care about. The Value Score = weighted, field-normalized spec quality ÷ price. Change a slider, the ranking recomputes live.
3. The formula is public. No black-box "editor's pick." The equation is printed on every category page. The only thing we add is the assembly — and we let you argue with it.
