detergent compartment

Hi y’all,I just got this robbot vaccum,and realised there is a compartment for a detergent unit,but I don’t seem to find the unit anywhere to buy it.
My question is where do I buy it!And can I just pour robbot vaccum solution straight into the water

What model did you purchase? They do have a pet detergent and a more general detergent for some of their units. I don’t know about the compartment itself.

Hello,

The E40 Ultra does not come with a detergent cartridge, nor does it support automatic detergent dispensing.

You only need to follow the instructions on the detergent bottle and pour one capful of detergent into the clean water tank.
