Narwal robot vacuums

• Does not matter
• Mostly hard floors (laminate, tiles, wood, PVC)
• A mix, with rugs or some carpet
• Mostly carpet

With carpet and rugs the robot must lift or drop its mop, or the rug gets wet.

• Does not matter
• Yes, pets
• Yes, long hair (no pets)
• No

Hair wraps around the brush. An anti-tangle brush prevents that; a camera that recognizes droppings prevents the other well-known accident.

• Does not matter
• Emptying the bin myself is fine
• As little as possible: it may empty itself
• Nothing: everything automatic, mop included

A station can empty the bin, wash and dry the mop and refill water. The more it does, the bigger and pricier it is.

• Does not matter
• Up to 0.8 in (2 cm), or none
• 0.8 to 1.6 in (2 to 4 cm)
• Higher than 1.6 in (4 cm)

Most robots cross 0.8 in (2 cm). Higher thresholds need a climbing system. Measure under your sofa too: a low robot fits underneath.

• Does not matter
• Rarely
• Sometimes
• Often

• Does not matter

It must also fit under low furniture (less than 3.5 in, or 9 cm, of room)
