Can be used in homes with pets. Its suction power of 1000pa is very effective on hard floors and medium pile carpets and the HEPA Filter will capture pet hair that finds its way into the hair you breathe.

The side tangle-free brushes will clean wall edges and corners effectively.

60 minutes – poor run-time as compared to most Roomba robots.

120 minutes – Good charging time, does not take long but still its run time is poor.

It randomly cleans and moves from room to room. It does not have a clear map or route but it will still do a great job.
