There’s no nice way to put it: scooping cat litter sucks. It’s a thankless task that can be one of the few downsides to cat ownership. You needn’t accept it though. The Litter Robot II Bubble could be just what you’re looking for.

The Litter Robot II Bubble may not be the very latest model in the Litter Robot range, but automatic litter box reviewsthat doesn’t mean that it doesn’t pack in some great features. Like all versions of the Litter Robot it’s manufactured by AutoPets so you can count on a long history of product design and success.

For many years this was the flagship product in the highly popular Litter Robot range and features much of the functionality of the newer model with a few notable exceptions. You can read about these below.

How Does It Work?

At the risk of repeating ourselves, this unit operates in much the same way as other Litter Robot models, including the Litter Robot III Open Air. However, unlike that model, the sensor is tripped when your cat puts weight onto the entry step. It then measures the weight of the cat when he’s inside the box to make sure a cat has actually entered. After he’s finished doing his business the timer starts and 7 minutes later the cleaning cycle begins.

When the 7 minutes are up the entire globe rotates, allowing clean litter to drop through the grate and collecting any solid matter before depositing it in the waste drawer. The waste drawer contains carbon filters which do a decent job of controlling unpleasant odors.

One of the concerns I hear frequently is whether these units are safe for cats. There’s absolutely no question that your cat will be perfectly safe while using the LItter Robot II. When the weight sensor is triggered it won’t allow the unit to rotate until the weight has been removed from the box. If your cat enters during the cleaning cycle it’ll stop and wait 15 seconds. If he’s still in there after 15 seconds the unit will remain deactivated.

The only problem you might have with this unit is the step. If your cat is a “jumper” and prefers to leap into the litter box the timer may not activated. If this is the case you may like to consider the Litter Robot III Open Air which removes the need for the step to activate the sensor.

The Conclusion

My cat Andrew was able to adapt to the Litter Robot II Bubble with few problems. The first time he climbed inside he was quite cautious but after the first couple of times he knew what he was doing. If your cat uses the box more frequently you may have to check the waste drawer periodically, at least to start with. You’ll soon get to know how much your cat uses the unit and therefore how often it needs emptied. I’d recommend the Litter Robot II Bubble. It’s missing some of the handy features of the Litter Robot III Open Air but it’s an effective unit that does exactly what it claims to.

Handy Hints
  • You may want to invest in a cat litter trapper. We recommend the EZ CLean.
  • We recommend one of the following cat litter brands for use with the Litter Robot III:
  • You will need to keep the litter box topped up with litter to ensure that clumps don’t get stuck on the globe
  • You should periodically change the carbon filters, perhaps once per month for average usage
  • The control panel isn’t waterproof so you may want to protect it with kitchen wrap
  • If your cat likes to jump get a ramp to make sure he will use the step of the unit to activate the weight sensor mechanism.
