$1 cheaper than the ATL
Lubluelu Self Empty Station SD85 is both a charging station and an auto-empty dock. It adopts automatic dirt disposal technology to free you from frequently emptying the dustbin. And the dust bag has a capacity of 2.5L that can hold up to 60 days of dirt.
Works with the SL60D and SL60D Pro, as well as the SL61.
1 Dust Bag Included, plenty of cheap dust bag options on Amazon and Aliexpress.
The standard dust bin (in the SL60D at least) is tiny, especially if you have a large house and pets.
The rationale for this is perfectly described by @Hinee:
If you already have an SL60D and no auto empty station I absolutely implore you to grab one at this price. Emptying the bin is not difficult, but it really should be done after every clean. Being able to completely forget you even have a robot vac for months on end (until you find it stuck under a bed with a sock jammed inside) is truly where these things shine. I've had mine for months and still haven't emptied the bag (though it's probably very due now).
We have one of these, and have just bought another for downstairs.
looks like a new dust bin is coming
"This SD85 dust bucket is about to be sold out. We have launched a new dust bucket D3 (B0DQCXJD3B). The D3 dust bucket is compatible with SL60D and SL68 robot vacuum. Welcome to purchase."
