Xa kuthelekiswa nezixhobo zemveli zemizi-mveliso, iirobhothi zamashishini zibonelela ngeenzuzo ezininzi. Oku kuquka ukusetyenziswa lula, amanqanaba aphezulu obulumko, imveliso encomekayo kunye nokhuseleko, ulawulo olulula, kunye neenzuzo ezibalulekileyo zezoqoqosho, ezibenza bakwazi ukusebenza kwindawo{1}}ezinobungozi obuphezulu.
Kwilizwe lam, iirobhothi zemizi-mveliso zisetyenziswa kakhulu kwimveliso, hayi kwishishini leemoto kuphela kodwa nakumacandelo amaninzi ahlukeneyo, ukusuka kwimveliso yeziphekepheke kunye nokuveliswa kwezixhobo zomkhosi ukuya -kuphuhliso lukaloliwe olukhawulezayo kunye nokuveliswa kwepeni yokubhala. Ukusetyenziswa kwabo kuye kwanda ukusuka kwimizi-mveliso esele ikhulile ukuya kutsho kwiinkalo ezifana nokutya namayeza.
Ngenxa yophuhliso olukhawulezayo lwetekhnoloji yerobhothi, umahluko wexabiso phakathi kweerobhothi zamashishini kunye nezixhobo zemveli zamashishini ziyacutheka, kwaye iimveliso zibonelela ngokwenziwa ngokwezifiso okukhulu. Ke ngoko, kwiinkqubo zokuvelisa ezintsonkothileyo, iirobhothi zoshishino zinokuthatha indawo yezixhobo zemveli, ziphucule kakhulu ukusebenza kakuhle kwezoqoqosho. Izibalo zibonisa ukuba ukuthengiswa kwehlabathi jikelele kweerobhothi zoshishino kwanda ukusuka kwiiyunithi ze-294,000 kwi-2016 ukuya kwiiyunithi ze-346,000 kwi-2017, ebonisa uluhlu olubanzi lwezicelo zeerobhothi zoshishino.
