He goes under our sofa without any problem, which is about 19/20cm above the floor.
If, for example, the fridge door is open, about 13cm above the floor, he also goes underneath without a problem, it doesn't bother him 👍

Hello Anonymous
Please excuse me, the Roomba j7 and j7+ only have a height of 8.7cm :) unfortunately there was a mistake in our previous comment. Please feel free to contact us again if you have any further questions or uncertainties.
Many greetings,

Hello
With its height of 9.5 cm, the Roomba j7+ can easily fit under a piece of furniture that is higher than 9.5 cm.
