WHY THE PRICE IS JUSTIFIED

The case rests on function: LiDAR/structured-light navigation, MopExtend, side-brush lift, hot-water pad washing and a self-emptying dock at sale prices. It is a value choice, not an endorsement of every newer feature.

Reliability & repairability

IDEAL FOR

·Hard floors with wall-edge dirt
·Sale shoppers seeking a full dock
·Pet hair

NOT FOR

·People unwilling to clean the dock base
·Homes with very deep pile as the primary surface

DESIGN & ERGONOMICS

The extendable mop is a thoughtfully visible solution to edge gaps. Dock/robot are cleanly styled, but the wash-base geometry is less pleasant to scrub and some owners report pad reattachment quirks.

LONGEVITY

Brushes, pads, bags and filters are normal consumables. Inspect the detachable-pad mechanism and clean the dock base; do not assume automation removes all maintenance.
