I've tested robot vacuums of all shapes, sizes and price-points, and with all kinds of specs. But how much suction do you really need in a robot vacuum, and what kind of specs should you look for?
Robot vacuum suction is measured in Pascals (Pa). The cheapest robot vacuums on the market might have in the region of 3,000Pa of suction. In the mid-range, you're looking at around 5,000-9,000Pa. Until recently, the absolute highest suction spec you'd find anywhere was 10,000Pa.
