For a new rug, vacuum (on low without a brush or a beater bar) 2-3 times a week is recommended.
Once the shedding is lesser, vacuum weekly. Do not over vacuum as it may damage the fibers and cause more shedding.
Every 2-3 years, seek professional dry cleaner to clean and maintain your rug's quality and durability.
Do not expose rugs to long period of direct sunlight.
Use underlay or nonslip pad to prevent discolouration of the floor.
