Does it need batteries?

Yes. The motion sensor and lid run on batteries, so plan on replacing them periodically. Battery life depends on how often the lid opens.

What size trash bag fits?

The 13.2-gallon capacity matches a standard tall kitchen bag. A 13-gallon bag is the usual fit.

It stands about 24.9 inches tall, so check the clearance under your counter before buying. Most standard counters leave enough room.

The lid is designed to open by motion. If the batteries run down, the lid stops responding until you replace them.

The sensor lid keeps the trash covered, but it can also open when a pet or child passes in front of it. Keep that in mind in a busy walkway.
