Yes, MOBOTs are firm rollers designed for deep tissue massage. If you're new to foam rolling, we suggest starting with thicker clothing or using a soft carpet to lessen the intensity of the massage. Over time, your muscles will adapt, and you'll become more comfortable with foam rolling. Remember to take it slow, breathe deeply, and make foam rolling a routine part of your daily self-care.

It's recommended to wash your MOBOT bottle and lid frequently, especially if you use it regularly. The wide mouth of the bottle makes cleaning easy, ensuring your MOBOT stays fresh and hygienic.
