How the matcher decides
The matcher runs 4 sets of comparisons in your browser — one per model in the catalogue. Each comparison returns one of four verdicts. A model appears in your results only if none of its verdicts rules it out. There is no score, no weight and no ranking.
The four verdicts
| Verdict | What it means |
|---|---|
| Satisfied | The manufacturer states something that meets the condition you entered. Nothing is inferred. |
| Works, with a trade-off | It can be done, but something else about the machine is worse for you — price, upkeep, floor space — and the site names it rather than burying it. |
| Ruled out | A published specification directly contradicts the condition you entered. This is the only verdict that removes a model from your results. |
| Not published | The manufacturer does not publish this parameter. The site says so instead of guessing, because a guessed value that happens to match your need is still a guess. |
Only “ruled out” removes a model. A model can reach your results full of trade-offs, and the site will show every one of them. That is deliberate: pretending a machine has no downsides is as dishonest as inventing one.
The checks it runs
Seven, in this fixed order. The order is why the “what ruled this out” list reads consistently.
| Check | Compared against | Ruling a model out needs |
|---|---|---|
| Budget | Australian price printed on the manufacturer page | A published price above your limit |
| Internal thresholds | Rated obstacle clearance | A rated figure below your tallest step |
| Pets | Published anti-tangle system | No anti-tangle system described at all |
| Flooring | Published carpet handling and mop lift | Nothing — missing mop lift is a trade-off, not a disqualification |
| Home size | Floor area | Nothing — area alone cannot rule a machine out |
| Maintenance | What the dock automates | Nothing — a preference the machine does not suit is a trade-off |
| Mopping | Published dock mop washing | You said mopping matters and the machine has no published pad washing |
The one judgement call: threshold headroom
Manufacturers state clearance as a maximum, and a maximum is a laboratory number: an ideal step, a charged battery, no carpet pile. This site therefore requires 1 cm of headroom below the rated figure before it calls a fit comfortable. A model whose rated clearance is exactly your threshold height still appears in your results, but it is labelled as clearing it with nothing to spare rather than as a clean fit.
That margin is a judgement, not a fact, and it is stated here so you can disagree with it. Change your threshold answer and the verdict changes with it.
Why there is no ranking
Results are ordered by published Australian price, lowest first, because that is the only ordering verifiable from the sources. It is not a recommendation order and the results panel says so every time. This site has never run any of these machines; a star rating here would be a number invented for a product nobody touched.
What happens when nothing fits
You are told which condition ruled out the most models, and why each one failed. The site does not offer you “the closest match” — a model that fails something you said mattered is not a match, however close it came. A button offers to relax exactly one condition, the most restrictive one, and re-run so you can see what changes and decide for yourself whether the trade is acceptable.
What it will not do
- Estimate a coverage figure per run. No manufacturer publishes a comparable one.
- Treat a missing specification as a negative one — unpublished is not the same as absent.
- Score, weight or rank models.
- Send any of your answers anywhere.
