A $600 Discount on a Robot Vacuum Answers the Wrong Question

Roborock cut up to $600 off its most expensive robot vacuums for the October Prime Day sale, which puts machines that normally sit near four figures into territory where people who were not shopping for one start looking.

A discount that large stops being a price and becomes a question: is this thing for me at all?

The answer depends on square metres more than on money. I live in a small flat. A robot that maps rooms, empties itself and mops on a schedule would spend most of its life bumping into the same three pieces of furniture, and I would still be sweeping the corners it cannot reach. At that size, a broom is not a compromise. It is faster.

Put the same machine in the house I grew up in and it changes the week. Big floor area, several rooms, dust that comes back before you finish the circuit. That is where cleaning stops being a ten-minute job and starts being an afternoon, and where a machine that works while you are out earns its price every single day.

So the discount is real and the deal is only good for half the people reading about it. The useful filter is not the price tag: it is whether cleaning your floors currently costs you an afternoon or ten minutes. If it is ten minutes, $600 off something you do not need is still money spent.

So, do I buy it? If you have a house, yes, and this is the moment. If you have a flat under about 60 square metres, keep the broom and spend it on something that gives you back more than eight minutes.
