How we rank
We never average review scores. We look at where 5 test sources (RTINGS, TechRadar, Tom's Guide, Vacuum Wars, and Wirecutter) place a model in their top lists: the higher it stands there and the more sources pick it, the higher its score. The price is today’s lowest at 6 stores, shipping included, before sales tax. How our method works →
Other models we track
Models that are not in our ranking, because none of our test sources recommends them. We do track their prices.

Where we check prices
We read prices every day at most stores, from their product feed or web store, and Amazon’s through price services such as Keepa. We check them for errors and keep them, so you can see what a price did over the last 90 days.
