Abstract: The present invention describes a method and a system for multi-level authentication of a user and a server. The user registration process in the invention enables user to personalize the web page of the server. Further, the user authentication takes place in a multi-step process including entering credentials such as user ID, subset of user's password, subset of shared secret and a One Time Password (OTP). The system of the present invention provides various means of entering the said credentials which prevents phishing attacks.

Abstract: Embodiments of the invention provide a paddle wheel mechanism for a pool cleaner. The paddle wheel mechanism includes a housing, a paddle wheel shaft supported by the housing, a first paddle wheel, and a second paddle wheel. The housing directs fluid from a fluid path of the pool cleaner into a first flow path and a second flow path. The first paddle wheel is supported by the paddle wheel shaft and is positioned within the housing along the first flow path. The second paddle wheel is supported by the paddle wheel shaft and is positioned within the housing along the second flow path. The first paddle wheel rotates responsive to fluid directed along the first flow path, and the second paddle wheel rotates responsive to fluid directed along the second flow path.
