2. Ili ndi machitidwe osiyanasiyana: Tanena kuti pali mitundu yambiri ya makina owombera kuwombera kuti azolowere malo osiyanasiyana ogwira ntchito ndi zosowa. Poyerekeza ndi makina ena owombera kuwombera, makina athu othamangitsira kuwombera ali ndi mitundu ingapo ya ntchito ndipo amatha kukwaniritsa nthawi ndi zofunikira zosiyanasiyana. Makina owombera owombera ali ndi liwiro lachitatu losiyana kuti woyendetsa asankhe, oyenera kupanga zofunikira zazinthu zosiyanasiyana, ndipo zonse zitha kukwaniritsa zomwe zikuyembekezeka. Tinganene kuti kukhala ndi seti ya crawler kuwombera makina ophulitsa kuli ngati kukhala ndi makina angapo owombera amitundu yosiyanasiyana. Utumiki wochuluka ndi chimodzi mwazinthu zabwino kwambiri zamakina ophulitsira kuwombera.
3. Kuchita bwino kwambiri kwa ntchito: Chifukwa chomwe ambiri opanga mafakitale amasankha kugwiritsa ntchito makina owombera owombera ndi chifukwa cha ntchito yake yapamwamba. The crawler kuwombera makina ophulika ndi osiyana ndi makina ena owombera kuwombera chifukwa amagwiritsa ntchito njira yogwirira ntchito ya olekanitsa, yomwe imatha kuyika bwino mitundu yosiyanasiyana ya mankhwala. Mwa njira iyi, mankhwala omwewo amatha kukonzedwa pa liwiro linalake, ndiyeno kukwaniritsa zofunikira za ntchito yabwino. Mphamvu yogwirira ntchito ya makina owombera owombera ndi amphamvu kwambiri, omwe ndi chimodzi mwazabwino zake zazikulu.
