Excellent price on this robot vacuum that ends up being cheaper than the Amazon Deal. I picked one up and it's been working great so far. It has an auto-empty station that it'll go to automatically when full or when it needs to recharge, it scans your rooms to work out the floor plan for better cleaning, can climb rugs easily, set virtual boundaries and more.
It has 2300pa suction power with 4 levels of suction, a mop attachment with 3 levels of cleaning, 3200mAh battery with 110 minutes of run time, voice control and unlike other robot vacuums it'll support 2.4/5GHz mixed Wifi networks - good for setups where they're not separated.
If you don't have eBay Plus buy from the Amazon link above as it works out cheaper than the normal eBay 20% off code.
