We tracked mud through our living rooms and kitchens to find out just how powerful the dock is when paired with the Roborock S7.

The Auto-Empty Dock is a first-party accessory for the Roborock S7 vacuum that reduces the amount of time spent emptying dustbins. The dock is 22.3 x 15.8 x 9.5-inches and weighs nearly 20lbs. A small ramp allows the vacuum to mount the dock to charge and empty the on-device dustbin.

When the Roborock S7 returns to the dock the vacuum determines whether the on-device dustbin needs to be emptied based on cleaning patterns. If the Roborock S7 is set to automatically empty then the dust is sucked into the 3L bag in the dock and sent through a HEPA filter to stop it from escaping into your home. Roborock claims that an average user will only need to empty the dustbin every eight weeks.

The auto-empty dock is available in white and black models, but right now both are sold out on Amazon, Walmart, and the Roborock websites.

The Roborock S7 and Auto-Empty Dock make a pretty weighty pair and it might seem like the setup would be difficult, but that’s far from the truth. When I unboxed the Auto-Empty Dock, all I had to do was screw the ramp into the twin-cylinder piece with the included screwdriver, replace the on-device dustbin, and place the Roborock S7 on the charging electrodes. Beyond those few simple steps, there’s basically nothing in the way of overhead.

Beyond those few simple steps, there’s basically nothing in the way of overhead.

This thing is smart. If the Roborock S7 is set to auto-empty, you don’t even have to think about the dustbin. The vacuum estimates when it needs to empty itself based on the size of your space and cleaning habits. There are manual options you can set that will determine how frequently the S7 will auto-empty, but I’ve found the “Smart” option to work very well so far.


On top of that, you can set “Do not disturb” quiet hours where the S7 can still vacuum but won’t empty into the dock, to avoid the loud noise. This is perfect if you like to have your vacuum clean other rooms in the house while you sleep but don’t want to be woken up by the noisy emptying process.

The biggest drawback for the Auto-Empty Dock is its price. There’s no sugar coating it — $300 for a non-essential accessory is pretty steep. It’s actually about $100 more than some competitors (like iRobot) are charging for similar products.

On top of that, it’s worth considering what that $300 will actually save you. I obviously didn’t have to empty my dustbin anymore, which was great, but I still found myself checking up on my S7 to refill its water tank and to clean its brushes. It wouldn’t have been a big deal to include emptying the dustbin in my regular maintenance routine, so I have to wonder whether that $300 investment is worth it, especially considering there are cheaper options on the market.

I ran into almost no issues while actually using the Auto-Empty Dock; however, I noticed that the S7 would sometimes leave a small pile of dirt at the base of the dock. The Roborock S7 drives up the small ramp of the dock, and when it leaves the ground it struggles to suck the remaining dust into its dustbin. I didn’t run into this issue every time the S7 finished a cleaning cycle but after some of the more demanding cleans (the oft-neglected area under my couch, for example) I noticed the small deposit of dirt.

The Roborock Auto-Empty Dock works exactly as you’d hope. It streamlines a large part of the regular maintenance and reduces the amount of time spent cleaning the Roborock S7.

The real drawback for this product is its hefty $299.99 price tag. There are quality standalone robot vacuums on the market for the same price, like the iRobot Roomba 694 ($274.99). So, is this accessory really worth it?

While the convenience and quality of the Roborock Auto-Empty Dock are fantastic, it’s difficult to recommend it because of the hefty price point. If you’re convinced that it is something that will benefit your cleaning process, then by all means go ahead — the dock is great! But, if you’re on the fence, I’d advise holding off on this one. A good deal or price drop might make this a smart buy, but for now, the Auto-Empty Dock is a pricey accessory that only adds marginal value to an already smooth user experience.

Top Roborock Auto-Empty Dock questions and answers

Q: Can I manually choose when the Roborock S7 empties the on-device dustbin?

A: Yes! The smart-empty option is great, but if you ever want to manually empty the on-device dustbin that’s possible too. You can do so from the app or by taking the dustbin out of the device as you would normally.

Q: Is the Auto-Empty Dock compatible with any other Roborock models besides the S7?

A: Unfortunately, the Auto-Empty Dock is only compatible with the Roborock S7. If you don’t have the S7 but still want to take advantage of auto-emptying you’ll need to invest at least $950 in the vacuum itself as well as the dock.

Q: Are the 3L bags that come with the Auto-Empty Dock reusable?

A: Roborock doesn’t say anything on their official website, although on the Amazon page there it is mentioned that the bags should not be reused. At the moment Roborock is not selling bags separately so if the two bags that come with the dock fill up, there is currently no solution for that.
