Works good

I was a little worried the new bonnet fit a little weird but it seems to be working good and has added litter a few times now so I’m happy with it.

Had to have this when I ordered my LitterRobot! Keeps the litter at the perfect level and makes things even more hands free.

Great automatic litter filler

This works like a charm!. It keeps the litter-robot's litter level always at its optimal level without any human intervention. Just check the bin level every week or so and add as required. Recommended!!

Dispenses every cycle and wastes litter.

The litter hopper dispenses litter every time the litter robot cycles rather than only when it is low. It also dispenses more than needed so that when the litter robot cycles, it dumps unused litter into the waste drawer. I have reset and calibrated when the litter was well below the fill line on the litter robot, as recommended, but that only works for a cycle or two then it returns to dispensing every cycle. In order to reset and calibrate I have to remove litter already in the globe so that the level is well below the fill line. This is much more inconvenient than adding a few scoops of litter myself when I notice the globe is low.

Easily installed in a few minutes, this add-on to my automatic litter does exactly what it’s meant for- keeping the litter properly filled.
Brings the process down to change the litter trash bag when the app warns you to, and refill the feeder once in awhile.

Review of LitterHopper

Posted by: Best Addition to Litter Robot 4.
This is the BEST addition to my Litter Robot 4!!!! It saves me the trouble of being sure I have the correct amount of litter in the box. It adds litter as needed to maintain the perfect amount. I love it and would highly recommended it!!!
