The Milwaukee AIR-TIP 2-1/2" Rocking Utility Nozzle w/ Brushes (49-90-2039) makes handheld and upright cleanup easier. The bevels on either side of the nozzle and brushes all around the tool ensure it won’t get stuck to surfaces when you clean in a rocking motion. This vacuum accessory can be used with 2-1/2" extension wands for greater reach. The 2-1/2" diameter allows for more debris to flow into the vacuum than smaller diameter tools. The bristles can be used in finished areas or when agitating debris for removal.
