Eufy Omni S2: two-minute review

Eufy’s latest flagship robotic vacuum and mop, the Omni S2 is a hugely impressive appliance that combines excellent mopping with brilliant vacuuming to create one of the best home cleaning systems you can buy. It also self-cleans so thoroughly that, after several weeks of daily use, the dust bin, rollers and mop still looked like new.
