  • 3Karcher
    1,220 PSI3rd

    (3rd best), 13.25 amps, 1.27 gallons per minute; needed about 10 seconds to recover from an initial pressure drop before reaching full pressure

  • 4Worx
    1,200 PSI4th

    (4th best), 13 amps (pushing the limit of the circuit), 1.34 gallons per minute (tied 3rd with Ryobi), took over 4 seconds to build to full pressure

  • 5Ryobi
    1,140 PSI5th

  • 8Sun Joe
    980 PSI

    (this figure is not stated directly in the Sun Joe's own passage, where the transcript cuts off mid-sentence after '...went from 620 to'; the 980 PSI value is recovered from a later sentence describing the Wen's result, which explicitly compares the Wen's 1,125 PSI 'to only 980 for the Sun Joe'), 10.1 amps, 71.5 dB, 1.1 gallons per minute

  • 8Sun Joe

    not included in the video's named top-5 cleaning-units ranking (weakest pressure and flow numbers of all 8 brands)

Soap Apply Rinse Time

  • 1Cat
    18 seconds

    to apply (fastest of all), 23 seconds to rinse (fastest of all), 41 seconds total (best of all brands)

  • 2Stanley
    19 seconds2nd

    to apply (fastest yet at that point), 30 seconds to rinse, 49 seconds total (2nd best)

  • 3Karcher
    24 seconds3rd

    to apply, 28 seconds to rinse (tied with Ryobi), 52 seconds total (3rd best)

  • 4Worx
    23 seconds

    to apply, 33 seconds to rinse, 56 seconds total (5th of the ranked group)

  • 5Ryobi
    26 seconds4th

    to apply, 28 seconds to rinse (tied with Karcher), 54 seconds total (4th best)

  • 6Wen

    rinse time 37 seconds (3 seconds faster than the Sun Joe's 40); apply time is captioned as '3 seconds faster than the Sun Joe at 25 seconds', which is internally inconsistent since the Sun Joe's own apply time was also stated as 25 seconds - based on the same '3 seconds faster' pattern used consistently elsewhere in the video (which checks out arithmetically for every other brand), the intended apply time was likely around 22 seconds, but the literal captioned figure is kept here and flagged rather than silently corrected

  • 7Yard Force
    29 seconds

    to apply, 36 seconds to rinse, both longer than average

  • 8Sun Joe
    25 seconds

    to apply, 40 seconds to rinse, both the slowest recorded

Wood Cleaning Test

  • 1Cat

    did by far the best job removing build-up and permanent marker stains, confirmed consistent on a second test board

  • 2Stanley

    performed nearly the same as the Wen, removing quite a bit of build-up after one pass

  • 3Karcher

    consistent spray pattern but did not remove as much build-up as the top performers

  • 4Worx

    regular (non-adjustable) tip gave a consistent spray pattern, performed better than Sun Joe but not as well as Wen or Stanley

  • 5Ryobi

    removed most of the build-up and the permanent marker stain, finishing 4th

  • 6Wen

    finished in 2nd place, removing a lot of build-up from a narrow portion of the board, though its adjustable nozzle pattern varied a lot

  • 7Yard Force

    consistent spray pattern but did not remove as much build-up as the top performers, grouped with the weaker-performing brands

  • 8Sun Joe

    removed only a small amount of build-up, with an adjustable nozzle pattern that concentrated most of the pressure in the center rather than an even spray

Durability

  • 1Cat

    no damage from the 36 inch drop test or from a vehicle driving over the gun handle

  • 2Stanley

    no damage from either the drop test or the vehicle weight test

  • 3Karcher

    survived the drop test, but sustained a lot of cracking damage on both sides of the handle from the vehicle weight test, though it still worked

  • 4Worx

    no damage from either the drop test or the vehicle weight test

  • 5Ryobi

    survived the drop test, but the handle cracked with some inner-side damage from the vehicle weight test, though it still worked fine

  • 6Wen

    no damage from either the drop test or the vehicle weight test

  • 7Yard Force

    no damage from either the drop test or the vehicle weight test

  • 8Sun Joe

    no damage from either the drop test or the vehicle weight test

How it was tested

  • baseline noise (dB) and motor current (amps) without a spray tip
  • baseline water pump flow (gallons per minute) without a spray tip
  • pressure (PSI), current, noise, and flow rate using a shared 3.7 GPM low-pressure spray tip
  • pressure (PSI), current, noise, and flow rate using a shared 3.0 GPM spray tip
  • total cleaning units (PSI times gallons per minute)
  • soap application and rinse time on a vehicle
  • wood surface build-up/mold removal using each brand's own hose and nozzle
  • spray gun drop durability (36 inch drop)
  • spray gun crush durability (vehicle driven over the gun handle)

The Cat is the best pressure washer, but it's also very expensive at $225.
