The short answer

GE 24" Portable Dishwasher with Sanitize Cycle is the only one of the two with a published score (4.6); KitchenAid KDTM604KPS has none, so this is not a close call so much as an unmeasured one. GE 24" Portable Dishwasher with Sanitize Cycle is best for: renters and small kitchens that want built-in-level cleaning without a permanent installation. Read the strengths below before deciding.

The GE GPT225SSLSS is a 24-inch convertible dishwasher with a stainless steel tub that rolls on casters and runs from a kitchen faucet, or can be fully installed. Reviewed found its cleaning and drying matched higher-end built-in machines, and Wirecutter names the GPT series its top portable pick for strong cleaning and an easy hook-up. Both note drawbacks: Reviewed measured heavy water use and a short cycle list, and Wirecutter points out it cannot run from a standard water line without extra plumbing. It suits renters and small kitchens with no dishwasher connection; anyone who can install a built-in machine, or who wants a tighter water budget, should look elsewhere.

Strengths
  • — Cleaned 98.5% of test stains on its Normal cycle and almost 99% on Heavy in Reviewed's lab
  • — Dries well, with only one or two items short of fully dry from a full load
  • — Input and output hoses come pre-attached, so hooking up to a faucet is quick
Watch-outs
  • — Reviewed estimates water use at over 1,394 gallons a year, more than twice a typical built-in
  • — Only three wash cycles and few ways to customise a wash
  • — Cannot connect to a standard water line without extra plumbing work

When third-rack capacity matters most, buy the KitchenAid KDTM604KPS. Its FreeFlex Third Rack is the deepest in the market, with its own wash jets and a stemware drying bar that genuinely help. The rest of the machine is a competent 44 dBA performer with the brand's usual better-than-average reliability.

Strengths
  • — ProWash sensor cycle scales wash time and water temperature to actual soil load
  • — Fan-Enabled ProDry circulates hot air for materially better drying than passive condensation, per Yale Appliance
  • — PrintShield stainless finish actually resists fingerprints in real-world use
Watch-outs
  • — No app-based smart features; not Wi-Fi connected

Derived means the reviewer published no score, so one was inferred from their written verdict. Everything else is a number the publisher printed. How we rank.

How they stack up

GE 24" Portable Dishwasher with Sanitize Cycle

Unlike the built-in LG LDTH7972S and Bosch 800 Series SHX78CM5N, the GE rolls on casters and connects to a kitchen faucet, and can later be converted to a permanent installation. It is a full 24-inch-wide machine, so it holds far more than the Farberware FCD06ABBWHA Countertop Dishwasher, but it needs floor space and a compatible faucet rather than a spot on the counter.

KitchenAid KDTM604KPS

The KitchenAid KDTM604KPS has the deepest third rack on this page, a FreeFlex rack with its own rotating wash jets and a stemware drying bar. At 44 dBA it is 2 dBA louder than both the Bosch 800 Series SHX78CM5N and the LG LDTH7972S, which are rated at 42 dBA. It has 5 wash cycles against the Bosch's 8 and the LG's 10, and no Wi-Fi, which the LG's ThinQ app provides.
