Yes! You can have multiple cassettes with the Joolca GottaGo!
At checkout, you'll have the option to pick either Eco Cassette or Chemical Cassette. If you want extra cassettes, or both options, you'll be able to purchase them separately.
Benefits of multiple containers/cassettes
Stay for longer: With a spare container, you can keep using the Joolca Toilet whilst emptying another tank.
Versatility: You can also use your Joolca GottaGo as an Eco (bagging or composting), or Chemical toilet if you have the compartments and want to change it up for different situations!
