I have two large verandas so large windows plus seven skylights. Supplied accessories: two pads bracket pairs + 7 pairs of reversible microfiber pads. Two extensions 4m. Security: cord and battery (power failure). Obviously I recommend this product and I'm satisfied that perfectly meets my expectations. The result is the rendezvous. If the windows are very dirty just change the pads and the restart as many times as necessary. Engine noise for aspiration is correct and quite bearable.
