Robot vacuums are the kind of household innovation our grandmothers could only have dreamt of. Yet, they're now a mainstream household must-have rather than a futuristic flight of fancy, sold by all major appliance brands, including Dyson and Shark.
A robot vacuum is a wonderful thing to own. I wouldn't be without mine - it's definitely one of the best vacuum cleaners I've ever owned - but the list of things I wish I had known before I bought it is long. So, if you're tempted to invest in one before Black Friday ends, I recommend first taking some time to understand what they can and cannot do. If you're picturing a world where you never have to pick up a vacuum cleaner again, I'm here to burst your bubble.
