## Verdict

Phantas is the pick for cluttered spaces like offices, hotel corridors, clinics and small shops, since it is under 45 cm wide and fits through 65 cm gaps. It handles both carpet and hard floors. Skip it if you have large open floors, because its small tanks and 33 cm scrub path make it slow there.
