The Roomba has gone through many upgrades over the years but still remains in the same relative shape until the new S9 came out, but who could afford that. The Roomba e5 is a great entry-level Roomba, although for the so-called budget price it should at least have better navigation than bouncing off objects like a ping-pong ball. What the designers finally thought was a good idea, using a glossy black panel to cover almost the entire top of the Roomba seemed to scratch my eyes. Attention Roomba, this is a vacuum cleaner, not a work of art. So dear Roomba, attach a camera to your "budget" Roomba and save us the hassle of watching the E5 speed past its charging dock.
