About the Onson 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 app, Alexa and Google Assistant control. It runs a zig-zag route, has spot and edge modes, and anti-drop and infrared sensors. Its suction is modest: the listing says 8000 Pa with two levels, while the spec sheet says 1400 Pa, so expect light-duty cleaning. The only price on record is $55.00 at Walmart as of October 31, 2026, with no other price points to compare against.

  • Low suction for the price class; spec sheet lists only 1400 Pa
  • No mapping or room-by-room navigation
  • Mop is a wet-cloth drag, not a scrubbing mop
  • 5 in tall body may not fit under low furniture
  • 3.3 out of 5 average from 2,100 ratings suggests uneven reliability

What reviewers say

  • 3.3 / 52,100 ratings

Ratings are middling at 3.3 out of 5 from about 2,100 buyers. Owners like the low price and the vacuum-and-mop combo for pet hair on hard floors, but many report weak suction, poor navigation and durability problems.

What people mention
  • SuctionCriticisedOwners say it struggles on carpet and only picks up light debris on hard floors.
  • NavigationMixedThe zig-zag route helps along edges, but there is no mapping and it can miss spots or get stuck.
  • Mop performanceCriticisedThe 230 ml tank runs dry fast and the mop drags rather than scrubs, leaving streaks.
  • Build qualityCriticisedSome owners report motors, batteries or wheels failing within the first year.
  • ValuePraisedBuyers say it does a decent basic job for a very low price.
  • Pet hairPraisedThe brushless inlet keeps hair from tangling and handles pet hair on hard floors well.

Questions and answers

Is the Onson 2-in-1 good on carpet?
Only for low-pile rugs and light debris. Suction is listed at 1400 Pa on the spec sheet, and owners say it struggles on thicker carpet.
Does it map rooms?
No. It cleans in a zig-zag pattern with spot and edge modes and has no mapping or room-by-room scheduling.
How long does the battery last?
The 2500 mAh battery is rated at up to 120 minutes and charges in about an hour. Real runtime is shorter with suction on high.
What comes in the box?
The robot, a charging dock, a dustbin, the 230 ml water tank and a HEPA filter. Check the listing for extra brushes or mop pads.
Is $55 a good price?
It is the only price on record, $55.00 at Walmart as of October 31, 2026, so there is no recent range to compare. At that price it is cheap for a combo unit, but expect budget performance.
Does it work with Alexa and Google Assistant?
Yes. It connects over 2.4 GHz Wi-Fi and supports both, plus app scheduling and manual control.
