Prior purchasing this robotic vacuum cleaner, I thought a robotic vacuum seemed like a silly gadget created only for those who are too busy to vacuum their floors.However, I have multiple pets-2 dogs and 3 cats. The floor in their room is always a mess, with dropped food and feathers constantly on the floor. I figured what can I loose by trying this product.The robotic vacuum is a perfect solution to my pet room issues. It sweeps easily and thoroughly- even underneath the cages. Hard-to-sweep feather dust is picked up, as well as food pellets. The dirt bin is large enough to pick up the daily mess on the floor. And I can set it on a timer, so the room is never in a poorly swept state.It also did a good job vacuuming under a king size bed, which is not reachable with conventional vacuum cleaners.So far it is one of the best convenience gadgets I have purchased in a long time.
