Seven litter boxes, seven refill plans

A low purchase price can hide a refill problem. Start with the exact part, then its delivered Canadian price and how often your cats actually use it. The quantities below help plan orders; annual cost depends on delivered refill prices and the number of cats.

Model and sourceRefill to identifyAnnual planningPurchasing pitfall
Litter-Robot 4LR4 carbon filter; drawer liner12 filters at one per calendar month. Bags and litter are extra.The LR3 filter is a different part. Washing the globe does not replace filter changes.
PetSafe ScoopFree SmartSpinSmartSpin deodorizer PAC00-18007 (US reference); waste linerAt the documented 15-day interval: 25 units, or 13 two-packs to cover 365 days from no stock.Confirm the Canadian replacement code. The rotating SmartSpin is not a disposable-crystal-tray ScoopFree model.
PETKIT Purobot Max Pro 2 · P9904Fitted PETKIT bags; N50 2.0 / P9223 deodorizerFor N50 at 30 days: 13 units, or five three-packs for a first 365-day supply. Count bag use separately.An Ultra refill is not automatically a Max Pro 2 refill. Match P9904 before adding it to a basket.
PETKIT PuraMax 2N50 2.0 / P9223The same documented 30-day N50 interval applies to this compatible cartridge, not to the waste bag or all maintenance.A shared deodorizer does not prove that the globe liner, bag holder or every accessory is interchangeable.
PetSnowy SNOW+SNOW+ Waste LinersLog actual bag changes before projecting a year. No universal interval is established here.Check the liner’s fit with the auto-sealing drawer. A generic bag’s litre rating alone does not validate that mechanism.
CATLINK Scooper Open-XOpen-X bags: 20 per rollUsing the maker’s weekly-change example: budget 53 bags, or three rolls, for 365 days with no starting stock.The official US store excludes Canadian delivery in its shipping text. Establish a Canadian supply route before relying on its price.
Neakasa M1 Plus LiteM1 family bags, 330 × 690 mmThe maker estimates 10–14 days per bag for one cat: about 27–37 bags for 365 days. More cats can change that.This is the maker’s estimate, not a measured RoboStead interval. Smell or drawer condition can require earlier emptying.

For the first purchase, round up both units and whole packs. Carry leftover stock into year two; do not charge for it twice. Example: five three-packs buy 15 N50 units, although the 365-day scenario uses 13. The two remaining units reduce the next order. Thirty days and a calendar month are not the same budgeting interval.

Budget cleaning time as well as refills

Whisker recommends a deep clean at least every three months, adjusted to use. PetSafe’s SmartSpin instructions distinguish versions with and without a litter-sifter cover, so follow the procedure for your unit. For the remaining models, use the exact manual for washable parts and drying; a sealed drawer does not make the whole base washable. We have not timed these seven machines under matched household conditions.

Quick answers

Before you buy

Can a kitten use a self-cleaning litter box?

Only within the exact manufacturer weight and age rules. Below the verified automatic-mode minimum, use manual or disabled cycling.

Which models avoid an indoor camera?

Litter-Robot 4, PETKIT PuraMax 2 and CATLINK Open-X have no product camera in the reviewed records. PetSafe and PetSnowy also have no reviewed camera evidence.

Do the Amazon buttons lead to the exact models?

Yes. Each button appears only after the exact Amazon.ca ASIN is matched. Price, seller and stock must still be checked on Amazon.ca.
