1. Staidriú struchtúrtha
Tá spás beag idir an rothar agus an rothar,
an rothar agus corp an phumpa, agus an rothar agus an bonn seachtmhara,
mar sin níl aon fréamh sa chosmhail óbha agus níl aon pháirtíocht ina bhfuil cáithfear.
2. Uasalas eacnamaíoch
Is uasal agus éadrom an fheafóid thrí-thiománach Roots,
gan glasú, beart saoil fada agus comhthéacs maith de phobal.
3. Sámhacht éadrom
Stuctúr simplí, éasca a úsáid agus a chosaint,
gan glasú i dtosach
níl aon uill ann sa mheán trasmitiú agus mar sin de.
4. Rith go glan
Tacaíonn an struchtúr fíor-ghluaiseach le rótar phumpa
baintear úsáid as bearna giorra i ngnéithe chruaite, agus baintear úsáid as béarlaigh uasleibhéal.
