This 10" wide multi-surface floor nozzle uses the high suction of a wet/dry vac to clean the floors. To vacuum pet and hair that clings to carpet the brush employs two directional thread lifters to lift the debris into the air stream. Additionally one quick push of the switch on top and the floor brushes drop down for deeper carpets. Most vacuum attachments do not offer so much in a single floor cleaning tool. The WS25030A wet dry vacuum accessory fits most shop vacuum hoses and wands with a 1-1/4-inch and 2-1/2-inch diameter with use of the included 2-1/2-inch to 1-1/4-inch adapter.
