Best portable dishwashers

Top pick: AIRMSEN Countertop Dishwasher — the best all-rounder for most people. It has a built-in 5 L tank so it needs no plumbing hookup, seven wash programs and an 18-hour delay start, and it's the highest-rated of the mainstream countertop units here.

Who the others suit:

• AIRMSEN Portable Countertop with 5 L tank — quietest of the bunch (45 dB) and the best-rated overall; pick it if you're in a small flat or open kitchen and noise matters.
• BLACK+DECKER 6-Place Setting — the one to choose if you want to fit plates and pans for a couple, not just mugs and bowls.
• Honeywell 24-Inch — a full-size freestanding portable on wheels for a whole family's daily load; reviews are thinner, so read them first.
• FOHERE / Simzlife — budget countertop options for a single person or an RV; expect smaller loads and more plastic.
• Danby 6-Place Setting — a solid mid-size step up if you want more capacity without a full-size footprint.

Countertop models hook to the tap and drain into the sink; full-size portables roll up to the sink and store away after.
