A:AnswerHi Lizzie , That definitely sounds like the battery or the charger is damaged also make sure the handle screw is in the back of the unit and tight.
A:AnswerHi Iar! There is no difference between these two models. The BH52210PC will come packaged in a plain carton whereas the BH52210 will come packaged in a Hoover emblazoned carton. Hope this clarifies things! ~Kenya, Hoover Customer Care

A:AnswerHi Dave, This sounds like the filter is getting clogged up very fast we recommend that you clean this filter very often because of the pet hair.
A:AnswerHello, It is possible that the switch is stuck in the "on" position. To turn it off simply push the switch forward. If this does not solve the problem, please give our Cordless Customer Service team a call at 1-888-679-2121 or message us on Facebook. We hope this helps! - Jenna
A:AnswerMine did this green/red flash when I had the charging cord plugged in and took out and then reinserted the battery. I left the battery in and then unplugged and replugged in the cord and then it changed to just flashing red (indicating normal charging). So, I would just make sure the battery is in place before plugging in the charging cord.
A:AnswerHi, when there is a red flashing light that means the battery is charging. When there is a continuous green light that means the battery is charged. Thanks!
