Just want to say thank you for the great product Received the 550 on last Saturday & watch it vacuum entire floor for the first time while my cat staring with curiosity .

On second day & today, 550 again did its job well done & impressed with the docking maneuver, very hi-tech.

Result ? a full of cat litter sand, crumbs, cat fur and my wife’s hair & it cuts almost 90% of my vacuuming.

The only thing that it can't do its job is on black carpet but that has been resolved completely.

Best regards.
