"František prodává pračky a sušičky."

Translation: František sells washers and dryers.

[lindgrn2]

Shouldn't " František sells washing machines and dryers." be accepted?

[AgnusOinas]

"František sells washing machines and dryers" is accepted and I don't see a new report.

[BoneheadBass]

I (native AmE) would expect that to be accepted, too. If you reported it, someone can see what you actually wrote, in case there was an overlooked error in your answer.
