My Scooba lasted 1 hour 50 minutes = 110 minutes the first time I used this battery! I find that impressive, even for a new battery. Scooba also seemed to run faster than usual, at least for the first hour of cleaning. I used other "spare" Scooba batteries. For example, my results with a Metapo battery have been very disappointing. The Metapo costs less so the extra $$$ spent on that HQRP battery is really worth it in this case. Sure, you can pay more $$$ and get an original iRobot battery, but
