When you buy a robot vacuum, I think it's safe to say you're buying it for convenience. You map out your cleaning zones. You schedule your cleaning. At the end of each cleaning cycle the robot even dumps the dirt into a reservoir which hold a fair amount of dirt, dog hair, etc. You come home and your floors are clean. Perfect.
However, with Dustin, all of that goes out the window if you want it to mop as well. I don't mind pulling off the cleaning cloth and replacing it with a clean one daily. Heck, I don't even mind refilling the tank with cleaning solution. However, this robot does not self regulate the fluid, so it becomes a constant drip, drip, drip until the entire tank empties itself. So. . . if you run a cleaning cycle and you have cleaning solution left in the tank, you must be there when it starts in order to fill the tank, the when it finishes in order to dump the remaining solution. Yes, you heard me correctly. The instructions even tell you to dump the tank after every use. What a waste. I didn't understand why initially, but apparently the engineers did not think to design a self releasing mechanism that shuts off the open valves the solution passes through when the unit finishes cleaning. So, since I failed to be there just as it was finishing its cleaning routine, the left over cleaning solution was all over the floor, all around the electrical cords and soaked into some of the wooden legs of the entertainment center it was stationed near. There is no excuse for such a lousy design on a unit this expensive. What I'm guessing is they threw out some price point close to $1000 to impress how good the unit must be, then sell it on Sam's Club for $200, which is probably closer to its actual value.
Also, there is no remote control to direct the unit if you have a specific area you want to spend a little more time on. Call me spoiled, but I've had considerably less expensive units which included a remote control hand piece that allows you to send the robot wherever you want. You can use the mapping feature on the Dustin app, but it's not as accurate. At the very least, they could have made that function available in the app itself.
I bought 4 of these units. 2 for myself and 2 as gifts. 2 are going back. I don't want to be responsible for water damage. I'll use the two as cheap cleaners with an occasional mop if I'm at home. Sadly, it's a big fail in my book. It's the daily mopping that left me especially excited about buying this vacuum. What a disappointment. Steer clear. There are better units at a comparable price point which don't mop but offer more suction and programing perks. So far, I haven't heard of anyone in the industry that has perfected the mopping part in an integrated robot vacuum. Thought this could have been it.
