SURFACE CLEANER Russian patent published in 2014 - IPC B08B6/00 

FIELD: process engineering.

SUBSTANCE: proposed cleaner comprises brush with its rod furnished with cleaning threads and fitted on rotation drive output shaft fitted in bearing case equipped with handle and rotation drive control board. Adapter sleeve is secured aligned with output shaft at bearing case and equipped with working cup fixed in place by retainer and made of electrifiable nonmetallic material. Working cup covers said brush while cleaning threads stay in contact with cup inner surface and are made of resilient material. Replaceable polyethylene jacket is fitted on said working cup to contact with working cup outer surface. Said jacket is secured at working cup by fast-release tightening tape fitted in groove made at said working cup. Working cup projection on the plane perpendicular to output shaft lengthwise axis covers protection of bearing case on said plane. At shaft rotation cleaning threads slide over working cup inner surface to cause electrical charges inducing electrostatic field of definite magnitude. Availability of electrostatic field causes attraction of impurities to outer surface of replaceable polyethylene jacket fitted on working cup.

EFFECT: expanded and improved operating performances.
