Facts as the maker states them. A dash means the maker does not name it. Each model’s page gives the source of every fact. Noise is the maker’s own figure, so we do not judge it, and a customer rating only counts from 20 reviews.

Score out of 10: 60% lab tests, 25% owners’ ratings at the stores that ship to the United States, 15% the maker’s facts. Price does not count. Only models a lab has tested are ranked, and only models sold in the United States count. Method. Models no lab has tested yet, so they are not in our ranking. We do track their prices.

How we rank

Six rules every robot is ranked by

The same rules for every brand, every day. No brand or store can pay its way up.

  1. Tested, or not ranked

    A robot enters the ranking only after a cleaning test. 173 have been tested so far.

  2. Price never counts

    A discount can’t lift a model. The price sits beside the score, checked every morning at 6 stores.

  3. Cleaning weighs most

    60% of the score is measured cleaning: carpet, pet hair, mopping, obstacles and navigation.

  4. Owners and makers have a say

    25% comes from owners’ star ratings at the stores that ship to you, 15% from the facts the maker states.

  5. Thin evidence counts less

    The fewer tests behind a result, the more we pull it toward the average of its station type, so one lucky run can’t top the list.

  6. Reviewers shown, not blended

    The picks of RTINGS, TechRadar, Tom's Guide, Vacuum Wars, and Wirecutter sit next to our score, so you can see where they agree.

How our method works →

5 tests, 5 different winners

The number one on the main list of each test we follow, and where that model stands in our ranking. Their picks are shown beside our score and do not count in it.

TestTheir number oneWith us
RTINGS ↗list as of September 25, 2026 Roborock Saros 10R rank 17 of 85 with an all-in-one station

Wirecutter ↗list as of August 4, 2026 Roborock Q7 M5+ rank 11 of 18 with a self-emptying station

The main list is a test’s overall top list, not its lists for a budget, pets or carpet, which we show too. The date is the day we last read the list.

Robot vacuum market report, September 2026 A median price of $699 and 8 new models.

Where we check prices

We read prices every day at most stores, from their product feed or web store. We check them for errors and keep them, so you can see what a price did over the last 90 days. We link to Amazon too, but show no Amazon price until we read it through Amazon’s own API. Until then the price is on Amazon itself.

Whose tests we use

The lab part of our score comes from the measured tests of Just A Dad Approved and Vacuum Wars.

Beside each model we also show where these testers place it in their own lists, without counting it in the score:

How we combine lab tests, owners’ ratings and facts into one score is on the method page.
