What testers say about the Eureka J20

For anyone whose floors are all hard and whose spills dry on before they are noticed, the Eureka J20 mops far better than it vacuums.

Two results from Vacuum Wars pull the Eureka J20 in opposite directions. Its flat roller mop lifted dried stains far better than the lab's average and left very little water behind, while its vacuuming mark lies far under the middle of the lab's field.

For mopping the lab's figure is 2.93 out of 5, with 2.58 as the midpoint. The roller cannot rise off the floor, though rivals whose dock also washes the mop lift theirs 10.5 millimetres, and on a rug it turns its cloth to a side that does not absorb instead.

Vacuuming is the weak point. Suction stops at 8,000 Pa in a class where 20,000 Pa is normal, the lab's test with sand worked into medium-pile carpet ended far below its average, and 84 per cent of the long test hair stayed wound round the brush. On carpet that means grit left in the pile, and with long hair in the house a brush to cut free.

Pros

  • Roller mop is fed fresh water as it turns and clears spills well TechRadar ↗
  • Builds an accurate map and works patiently around table legs TechRadar ↗
  • Dock handles emptying, refilling and drying with little effort from you TechRadar ↗
  • Among the best at lifting dried stains, and leaves floors barely wet Vacuum Wars ↗
  • Turns its roller cloth to a dry side so rugs stay dry Vacuum Wars ↗
  • The app does what is needed, with maps per floor and zones to avoid Vacuum Wars ↗
