• Does not matter1, 1 model
• Mostly hard floors (laminate, tile, wood, vinyl)1, 1 model
• A mix, with rugs or some carpet1, 1 model
• Mostly carpet1, 1 model

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

• Does not matter1, 1 model
• Yes, pets1, 1 model
• Yes, long hair (no pets)1, 1 model
• No1, 1 model

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

• Freshening is enough0, 0 models
• Yes, real mopping0, 0 models

Mopping freshens the floor; real stains rarely come off. Spinning or roller mops paired with self-cleaning stations deliver the most effective floor cleaning.

• Does not matter1, 1 model
• Emptying the bin myself is fine1, 1 model
• As little as possible: it may empty itself1, 1 model
• Nothing: everything automatic, mop included0, 0 models

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

• Up to 0.8 in (2 cm), or none1, 1 model
• Higher than 0.8 in (2 cm), up to 1.6 in (4 cm)0, 0 models
• Higher than 1.6 in (4 cm)0, 0 models

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

A robot with a camera recognizes small items and drives around them. Without one it drives over them or gets stuck.

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

• Does not matter1, 1 model

The dock must connect to the water supply and the drain, so I never fill or empty a tank (with a separate kit on some models)
