The flagship price is the most consistent hesitation. Strong cleaning and automation help justify it, but several less expensive robots deliver similar results in selected areas.

Reliability is mixed: firmware support has been active, but early recall concerns and occasional app disconnects temper confidence. The short warranty also feels conservative for such an expensive machine.
