W&H Lisa 17L vs MELAG Vacuklav 31 B+

In short: both are Class B units with the same 17 L chamber, but the Lisa 17Lruns a noticeably faster cycle (13 vs 20 minutes) and weighs less (46 vs 55 kg). The Vacuklav 31 B+ publishes a known water draw per cycle (0.7 L) and carries no MOQ — the Lisa 17L's water consumption isn't published yet, so that field shows as pending rather than assumed.
