Introducing PUCRC25 - Our easier than ever no frills solution to automated home cleaning. Simply said PUCRC25 outmatches other entry level robot vacuums. Where other models skimp - we come through with a removable dustbin, dual rotating side brushes, and edge sensors that can detect stairs and automatically divert the robot away - damage free. After a 4 hour charge the unit can run up to a max of 90 minutes before needing a rest. Got allergies? Pets? The brushless suction design prevents the automatic cleaner from getting clogged in homes with cat or dog hair and can help make your household an allergy free safe zone. The robot is good at a lot of stuff - but don't expect it to go between different floor types if there is a barrier. Also it will have toruble on thick soft shag carpet.
