Had this on my watchlist for quite sometime,usually retails for $329 + shipping.
As per folks on OzB, Kogan SmarterHome LX16 Robot Vacuum is rebadged lubluelu SL60D (30 kPa). The only difference could be higher battery capacity on LX16, 3200mAh viz-a-viz 2600mAh; and 40kPa suction on newer SL60D's (apparently).
Recently bought the lubluelu SL60D from Amazon AU for ~NZ$230 and it's a solid product at this price point.
What do you mean by limited OP
