Yesterday I tried it on an indoor rug. Today I gave it a harder test — probably the dirtiest carpet in the house. Same idea, but with double the twigs.
I left the intelligent dirt detection on, so it kept going over the area. It took almost 15 minutes, which makes sense given how dirty it was.
I think it truly surprised me.
Would I use a robot on this carpet regularly? Probably not. But good to know it can handle it when needed.
