I have now had my B300 for more than 3 months using it at least twice a week. Still amazes me how much this PoolBot sucks into its large filter basket. Does an excellent job of cleaning the pool floor. Battery lasts about 4 hours. The app works well and is easy to use. I have experimented with all the available options and have found the setup that works best for my pool, this makes a big difference i found so is worth the effort. Just one minor negative, it is a big unit that my wife struggles to lift out of the pool but i have no issues. Our pool has the infloor cleaning which has been giving a lot of problems so i invested in the PoolBot and it hasn't disappointed. It has also cut our pool electricity bill in half because we now longer have to run the pump for the infloor cleaning jets. 100% happy.
