Clearance check
Measure the gap at the lowest point under the furniture and the height of your tallest door strip. Take the robot's full height from the listing, including the lidar tower.
In short
A robot fits if the gap is at least 0.5 cm more than its full height, and it climbs a threshold if the strip is no higher than its stated climb in mm. Under 1 cm of margin is tight, because castors and carpet pile lift the robot.

Under the furniture
Fits
Margin 1.3 cm (0.5 in)
Door threshold
Climbs, but borderline
Margin 2 mm (0.1 in)
Fits when the gap is at least 0.5 cm more than the robot; under 1 cm of margin is tight. Borderline when the threshold is within 2 mm of the climb limit. Maker heights include the lidar tower unless the listing says otherwise. Type decimals with a point, for example 9.7.
How to measure
Slide a tape measure or a ruler under the sofa or bed at its lowest point, usually a cross rail or the front edge, and read the gap from the floor. On carpet, press the tape down to the backing and then allow a little extra, because the robot rides on the pile.
For thresholds, measure from the lower floor to the top of the strip. If the strip is only a few millimetres too high, a small threshold ramp is the usual fix.
