I’ve been using cleaners over 20 years. But offdust was quite different. I just tried them since they promoted their company in my gym building. I am so far a very happy customer. They don't need to be told what to do. They just power through the house even doing things I hadn't noticed needed doing. I can't believe they use a steam cleaner for bathroom! I would highly recommend offdust to anyone wanting an absolutely thorough clean.
