Is the Roomba 105 worth it?

At $140 it is one of the cheapest self-emptying robots you can buy. If you want hands-off daily cleaning on hard floors and low-pile carpet, it is a reasonable buy. Expect basic navigation, not smart mapping.

How does it compare with the Roomba 105 Combo?

The 105 is vacuum-only. The Combo version adds a mopping pad and water tank. If you only need vacuuming, the plain 105 costs less.

How long does the battery last?

iRobot rates the Roomba 105 for roughly 90 minutes of runtime, enough for a small apartment on one charge. It returns to the dock to recharge and resume.

Does it work with Alexa and Google Assistant?

Yes. It supports Amazon Alexa, Google Assistant and Siri, so you can start, stop and send it home by voice.

The vacuum, the AutoEmpty dock, a power cord and a filter. No bags are needed because the dock is bagless.

Its lowest recent price was $140 at eBay on November 3, 2026, against a high of $179.99 the day before. Holiday sales are the usual time to watch for drops.
