Thresholds0.8 to 1.6 in (2 to 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.

Floors
- 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.
Hair
Hair wraps around the brush. An anti-tangle brush prevents that; a camera that recognizes droppings prevents the other well-known accident.
Mopping
Mopping freshens the floor; real stains rarely come off. Spinning or roller mops paired with self-cleaning stations deliver the most effective floor cleaning.
Upkeep
- 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.
Clutter
A robot with a camera recognizes small items and drives around them. Without one it drives over them or gets stuck.
Low furniture
It must also fit under low furniture (less than 3.5 in, or 9 cm, of room)
