                                            DIRECT SUCTION VS. BRUSH ROLLER 
   
                                               The direct suction design allows LS1 to vacuum dust, debris, and hair directly into the dust tank without tangling a roller brush. This eliminates the hassle of untangling the brushroll and saves you the cost of replacement brushes. Additionally, since the suction port won't get tangled, LS1 provides consistent suction power, which is perfect for home with pets.
