The first cleaning portion is provided on an upper surface of the base portion to project upwardly from the upper surface of the base portion and extend in one direction through a geometric center of the base portion in a plan view. The second cleaning portion is provided on the upper surface of the base portion to project upwardly from the upper surface of the base portion and extend along an outer edge of the base portion. Alternatively, one or a plurality of pairs of second cleaning portions may be provided on the upper surface of the base portion to project upwardly from the upper surface of the base portion and be opposite to each other with the first cleaning portion interposed therebetween."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lower-surface brush, brush base and substrate cleaning device","description":"A lower-surface brush includes a base portion, a first cleaning portion and a second cleaning portion.
