A:Answer The shark will go under some furniture, but it is limited. Floors under low couches or chairs don't work. Also, stools and chairs less that about a foot between the legs will also not work. This machine first maps the floor space in your house, which takes a few hours. After that you can program it to clean the entire house or individual rooms, as needed. It can be controlled from your phone with the downloadable app.
The biggest issue I've found is with pet hair. We have a golden retriever that sheds a lot. The robot manual says that you should clean the brush rollers periodically. It doesn't say that the "error 2, obstruction" can occur when pet hair fouls the brush roller. This is easy to clean out, but it is not "an obstruction" and the manual is not really clear on this. We spent days trying to fix the obstruction error, thinking that it was an issue with the "feeler" brushes getting stuck. Once we cleared the brush roller, the light dawned. Once we'd figured that out, the Shark has worked perfectly. If you have animals or very deep pile carpeting or if you sew a lot (thread lost on the floor), I'd recommend that you clean the brush roller after every two or three uses. Doing this maintenace takes about as much time as emptying and replacing the dust bag in a regular vacuum.
Hope that that helps.
