The present invention relates to apparatus and a method for cleaning a well. In an embodiment, the apparatus ( 10 ) includes a well cleaning tool ( 12 ) coupled to a support string 26 , which may be located in well tubing ( 14 ) to permit cleaning of the well tubing ( 14 ). The cleaning tool ( 10 ) may restrict fluid flow past the tool, for example, in an annular space between the tool ( 12 ) and the well tubing ( 14 ). Further, the tool ( 12 ) can be translated relative to the well tubing ( 14 ) to displace fluid along the well tubing ( 14 ) and thus clean the well.
