Litter-Robot 5

Supported household size

5 cats maximum

Whisker lists Litter-Robot 5 for households with up to five cats. The separate automatic-weight minimum remains Unknown because the product page and manual conflict.

Automatic-mode cat weight

Empty device weight

28.7 lb

Entryway dimensions

Wi-Fi requirements

2.4 GHz Wi-Fi with IPv4 or IPv6; 5 GHz is not supported

No. Official product and onboarding guidance require 2.4 GHz Wi-Fi with IPv4 or IPv6 and say the 5 GHz band is not supported.

Compatible litter

Standard-weight clay clumping litter is recommended; small beads or crystals may work if they pass the screen. Non-clumping, newspaper-based and absorbent wood-pellet litter are not supported. White or translucent litter may reduce litter-level sensor accuracy.

Use standard-weight clay clumping litter. Small beads or crystals may work if they pass the screen, but white or translucent litter can reduce level-sensor accuracy. Do not use non-clumping, newspaper-based or absorbent wood-pellet litter.

Whisker+ requirement

No

No. Whisker+ is an optional enhancement for deeper history and insights; SmartScale weight tracking remains available without membership. Current prices are dynamic and are not frozen here.

LitterHopper requirements

17.3-cup capacity; Litter-Robot firmware 5.9.6+ and Whisker app 1.38+ required before installation

Use the Litter-Robot 5 LitterHopper. Whisker limits it to Litter-Robot 5 and 5 Pro, lists about 17.3 cups capacity, and requires firmware 5.9.6+ plus Whisker app 1.38+ before installation.
