Is the Onson 2-in-1 worth it?

At $55 it is a cheap way to automate light dust and hair pickup on hard floors. If you have wall-to-wall carpet or pets that shed heavily, spend more on a stronger model.

How strong is the suction?

The spec sheet lists 1,400 Pa, while the store highlights claim 8,000 Pa. Treat it as a light-duty vacuum and do not expect deep carpet cleaning.

How long does the battery last?

The 2,500 mAh lithium battery is rated for up to 120 minutes and charges in about an hour. Runtime drops when you run the mop and use higher suction.

Does it work with Alexa and Google Assistant?

Yes, it connects over 2.4 GHz Wi-Fi and supports both. It does not work on 5 GHz networks.

What comes in the box?

You get the robot, a charging dock, a dustbin, a 230 ml water tank and a HEPA filter. Mop pads and spare brushes are usually sold separately.

Its lowest recent price was $55 at Mercari on October 31, 2026, and it was still $55 on November 3. The high in that window was $87 on November 2.

About the Onson Robot Vacuum Cleaner 2 in 1 Robot Vacuum and Mop Combo

The Onson 2-in-1 is a budget robot vacuum and mop combo with a 230 ml water tank, a HEPA filter and a charging dock. It runs up to 120 minutes on a 2,500 mAh battery and charges in about an hour, and it works with Alexa and Google Assistant over 2.4 GHz Wi-Fi. Suction is modest: the listing claims 8,000 Pa, but the spec sheet says 1,400 Pa, so expect light-duty cleaning rather than deep carpet work. At $55 at Mercari as of November 3, 2026, it sits at the bottom of its recent $55–$87 range, which is where it has been since October 31.
