Shark 2-in-1 Self-Empty Robot Vacuum & Mop RV2620WAUK
£198
Looks like a solid price for the Shark 2-in-1 Self-Empty Robot Vac & Mop. It usually goes for around £399 elsewhere, and while it's dipped a bit lower than that before, this looks like the lowest it's been for a new unit. Comes with Sonic mopping too, which is a nice touch.
