This takes the Litter Robot 4 to the next level!!! It makes the whole package complete ????

A bit disappointed with the litter hopper, it is not maintaining the litter level in my robot. I followed all instructions when installing and it is dispensing litter, but its such a small amount the litter level gets way too low and i have to manually add litter. Until they come up with a way to manually tell it to dispense litter, i wouldnt buy it.

Works nicely, but installation was more tricky than expexted. I did have a pretty big gap in the front of the hood at first I couldn't figure out how to fix. Found someone on Reddit explaining the issue, there are some nooks in the front you need to make sure are in the right spot too. This wasn't an issue with the normal hood that automatically was in the right spot, as the fit of the hopper lid is much tighter. Also the sticker on the hood doesn't match the placing of my robot buttons, not even close. It's in a totally different spot and looks bad. Doesn't impact function though but still a bit disappointing.

So far so good. Installation was pretty straight forward. So far we have had it a week and have not had to touch the litter box one time. Litter is added when needed automatically. If your goal is to have a litter box you practically only touch weekly or so, this is the accessory for you.

I had great hopes for this but it consistently leaves the litter level too low which results in cat waste sticking to the liner and not dumping. I know it isn’t supposed to fill to the ‘Max’ line but it doesn’t fill enough for the robot to be effective. When I fill it manually I do not have this issue.

The litter hopper doesn't keep the litter robot full at all. I can manually make it dispense, but it is not enough to do anything. You would have to sit there and make it dispense 4 times to get any amount of litter. I still have to go every day and add litter.
