Genuine Makita vacuum cleaner nozzle rollers (4) and nozzle wipers (2). The rollers can be easily removed by prying with a flathead screwdriver. If you feel the movement is poor, please try replacing them. You'll be free from stress. Compatible with your Makita vacuum cleaner: 7.2V 10.8V 14.4V 18V These are the 20.5cm long, thin rubber pieces located on the back of your rechargeable cleaner. Have you ever taken a look at your nozzle wiper rubber? I don't think many people pay attention to it. With a vacuum cleaner used for many years, the nozzle rubber will wear out and no longer completely suck up the dust. By changing the rubber wiper, the airtightness will definitely improve and you'll be able to suck up a lot of dust. ● How to remove: The rubber can be removed by pulling it out by hand. ● How to insert: The rubber wiper can be easily inserted while pushing it in with a flathead screwdriver. Please replace them at this opportunity. Nozzles are not included. Shipping is available immediately via regular mail. Delivery may be slightly delayed if it includes weekends. Available for purchase on December 25th. For those in a hurry or who prefer anonymity, shipping will be switched to Yu-Packet Post, which will be an additional 80 yen. Please let me know before purchasing. Type...Handy
