It was reported that Malerato Harrison was crushed by cleaning products and died as a result of her injuries.
She was working at Jasmond Central Woolworths in Newcastle, Australia, when she was trampled by equipment that reversed onto her.
Her death is not being treated as suspicious by police.
A flood of tributes has been pouring in for the beloved cleaner.
Malerato’s friend Jessika Abra wrote on Facebook: “I still can’t believe I’ll never see your big beautiful smile in person again or hear you laugh.
“You have touched so many people’s lives and made an impact on them.
“You’ve done so much for me without you probably even knowing and given me so much advice that I will always cherish.
“You don’t meet many people in life like you and I’m so blessed that I got to have so many memories and to have had such a beautiful friendship that I’ll always hold close to my heart forever.”
Another friend commented: “Thank you for being the most beautiful soul.”
“You were. You are. You will always remain a shining light in our heart,” wrote a third.
A mother of two, Malerato had moved to Newcastle from South Africa with her husband and two children.
In an interview with 9 News, her friend Tiana Campbell said that “every time she‘d say their names, her eyes would just light up.”
Mom-of-two worked for a third-party cleaning company that provided specialist services for Jesmond’s store.
According to Woolworths, the supermarket giant is “deeply saddened by the tragic incident ”.
“We are assisting SafeWork NSW and NSW Police as well as working with our contract cleaning partner,” he said.
In a statement, the supermarket said its first priority is assisting the woman’s family.
