How we choose

What a product needs to be included

Connection standard and male or female end stated for each end of any hose, gun, wand, adapter or attachment
M22 parts state the 14 mm or 15 mm bore
Maximum PSI and GPM rating stated, and maximum water temperature for hoses and guns
Nozzle tips state the orifice size number as well as the spray angle
Hoses state inside diameter, length and construction
Identifiable model or listing with stable specifications

What we exclude

Detergents, degreasers, soaps, foam concentrates, bleach and other chemicals (foam cannons are covered as hardware only, with no product or mixing-ratio recommendation)
Safety guarantees for any part, and advice that treats the spray as safe on skin; the site never suggests pointing a wand at a person or animal and points to the maker's manual for injection-injury warnings
Advice to exceed a part's PSI, GPM or temperature rating, or to fit a part rated below the machine's output
Advice to remove or defeat trigger locks, unloader or thermal relief valves, or to modify a pump or engine
Hot-water and steam use of parts not rated for it, and fuel, oil or engine-repair advice
Electrical advice for corded machines (extension cords, GFCI wiring or repair)
'Universal' or 'fits all' fit claims without the actual connection standard stated
Cleaning-result, paint-safe or 'safe on every surface' claims
Complete pressure washers as recommendations (they appear only as the reference machines that parts fit)

Evidence labels

Tested by us: A named person used the exact product and variant and recorded the method, dates, results and limitations.
Research-based analysis: We compared published information from several sources without testing the product ourselves.
Manufacturer specification: The figure comes from the maker's documentation and has not been independently checked.
Seller claim: The figure comes from a marketplace listing and has not been independently checked.
Independent source finding: A named third party published the finding; we attribute it rather than repeat it as our own.

Prices

Articles do not contain prices. Where a price is shown, it is the merchant's quote for the shipping destination you chose, with the time it was checked; it disappears when it is no longer current. The price at checkout can differ.

Commissions and editorial choices

We may earn a commission from qualifying purchases. Commission rates do not decide which products we recommend, and any paid placement is labeled as such.

Dates

"Editorially reviewed" dates change only when someone re-checks the article. Price checks do not change them.
