Abstract
A pool/spa skimmer includes a housing, a face plate, and a flexible weir gate. The housing and plate are dimensioned to allow water to flow in a vertical column. The interior of the housing has a curved wall so that when a column of water passes through the open gate and into the housing, a whirlpool effect is realized. A vertical filter cartridge is mounted on a rotational bearing so that it can spin about its axis. The inlet of a pump is coupled to the cartridge via the bearing and is also coupled to a second water inlet via a vacuum operated valve. When the filter is clean, water is drawn through it and the filter spins about its axis due to the whirlpool effect. When the filter reaches a threshold dirt covering, water is no longer drawn through it and the vacuum operated valve.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
