An extending brush or mop can improve reach near some boundaries, but furniture geometry still limits access. Evaluate your actual recesses and corners.

A practical checklist

  1. Compare the robot body's ability to approach the edge.
  2. Measure deep plinths and low overhangs.
  3. Plan occasional manual work in spaces the mechanism cannot physically enter.

What this looks like at home

A mop arm reaching beside a straight skirting board may not reach far beneath a deeply recessed cabinet.

Make the route predictable

Check What matters
Floor-level objects Lift leads, strings and loose fabric.
Narrow gaps Check entry, turning and escape space.
Protected areas Use suitable boundaries around hazards.

A mistake to avoid

Do not interpret edge cleaning as proof of complete corner or under-cabinet coverage.
