The best self-cleaning litter boxes

A self-cleaning litter box sifts waste into a sealed drawer after each visit, so you empty it a few times a week instead of scooping every day. They are a big purchase, so size, running costs and your cat's temperament matter.

Litter-Robot 4

Litter-Robot is the best-known name in self-cleaning boxes. The rotating globe sifts clumps into a lined drawer after each visit, and the sensors track visits and tell you when the drawer is full. It's expensive, but many owners say it changed their routine.

Good

  • Proven, well-supported design
  • Strong odour control with a sealed drawer
  • Visit tracking can flag changes worth raising with your vet

Watch out for

  • Very expensive
  • Big, so measure your space first
  • Kittens must reach the manufacturer's minimum weight
Best value self-cleaning box

PETKIT Pura Max 2

The Pura Max 2 gives you most of what a Litter-Robot does for noticeably less money. It cleans automatically, has a useful app, and the deodoriser helps in flats where the tray sits close to living space.

Good

  • Much cheaper than Litter-Robot
  • Takes common clumping litters
  • Smaller footprint

Watch out for

  • Large cats may find the entrance tight, so measure your cat
  • Deodoriser refills add to running costs
Best simple design

PetSafe ScoopFree

A rake sweeps waste under a cover after each visit, and every few weeks you bin the whole disposable tray. It's an open design that's closer to a normal litter tray, so wary cats often accept it quickly.

Good

  • Feels familiar to cats
  • No scooping and no litter to measure
  • Fits where a normal tray goes

Watch out for

  • Replacement trays are an ongoing cost
  • Some cats dislike crystal litter
Buying advice

How to choose

Measure twice

Globe and drum boxes are much bigger than a normal tray. Check the height, depth and the space needed to open the drawer.

Introduce it slowly

Leave it switched off with litter in it for a few days, next to the old tray. Switch on automatic cleaning once your cat uses it happily.

Work out running costs

Add up liners, deodoriser refills or replacement trays over a year. The cheapest box to buy isn't always the cheapest to run.

FAQ

Common questions

Are self-cleaning litter boxes safe for cats?

Reputable models use sensors to pause cleaning when a cat is inside. Follow the manufacturer's minimum weight guidance and supervise the first few uses.

Can I use any cat litter?

No. Drum and globe designs need clumping litter, and rake designs like ScoopFree use crystal trays. Check the manual before you buy litter in bulk.

How often do I empty it?

For one cat, usually every few days. Multi-cat homes will empty the drawer more often.
