                                Consumer Reports.  In our lab tests, Robotic Vacuums
                                models like the Deebot 500 are rated on multiple criteria, such as those
                                listed below.
                            
                                                        
                                Carpet:
                                A high score means the vacuum effectively removes surface debris and embedded dust from medium-pile carpet. A top-scoring model picks up more debris from carpet per run.
                            
                                                        
                                Bare floors:
                                A high score means the vacuum effectively removes surface debris like sand from smooth hard floors. A top-scoring model picks up more debris from non-carpeted flooring per run.
