Overall I am very happy with this product and its functionality. I previously had a shark unit that held up to 30 days of vacuuming in the box and I thought it couldn’t get much better than that till this one came along! I love that this unit can hold up to 45 days worth of vacuuming, it come in handy if you plan to run it everyday. Emptying is also easier! The canister built Into the dock is very easy to remove and replace. No bags needed! It’s fairly simple to set up and map your home, after that the real features come in where you can send it to a single room or even go over a single spot! This robo-vac is definitely worth the hype. I would suggest it to anyone who has been thinking of making the purchase.
