Reader-Favorite 2-in-1 Robot Vac-Mop Returns to Walmart for $99.58
Compact Onoson model, which has retailed as high as $400, is back under $100 as retailers press seasonal promotions

A compact 2-in-1 robot vacuum and mop that readers have praised is back on sale at Walmart for $99.58, a significant markdown from previous prices, according to a HuffPost report.
The Onoson model, offered in black, white and blue, combines vacuuming and light mopping functions and is being marketed on features that include a claimed 120 minutes of runtime, automatic docking and recharge, app control, voice compatibility with Alexa and Google Assistant and scheduling capabilities. The device has a removable dustbin and a separate mop tank that users can swap depending on the cleaning task, and the manufacturer advertises sensors intended to prevent collisions and drops from stairs.
HuffPost noted the sale follows prior periods when the model was offered at about $159 and at times retailed for as much as $400. The outlet’s deal-tracking methodology seeks to verify discounts by comparing current retail prices with historical listings and consumer ratings; HuffPost said the products it highlights are typically rated at least four stars and show meaningful discounts. The last time this Onoson model was featured by the outlet, it prompted a surge of purchases, a pattern retailers often expect when a widely recommended product returns to a sub-$100 price point.
Customer reviews cited by HuffPost and on Walmart’s product page describe the device as a useful daily cleaner rather than a substitute for deeper manual scrubbing. Multiple reviewers praised the robot’s suction on surface debris, low noise and the convenience of automated scheduling. One reviewer called it a “perfect little helper,” while others noted it excels at picking up pet hair and everyday crumbs but will not handle heavy stains or deep-set dirt.
The unit includes a three-stage filter, a spinning side brush with two extras, a remote control and a mop tank that is filled with water for light mopping. Users have highlighted the device’s ability to maintain cleaner floors between manual cleans and the convenience of letting the robot run while away from home. Several reviewers also advised periodically emptying the dustbin during pet-heavy cleaning cycles to sustain performance.

The current promotion reflects broader dynamics in the consumer robotics and home appliances market, where discounting, model refreshes and promotional events frequently compress prices on older but still-popular models. Retailers such as Walmart commonly use short-term markdowns to clear inventory, attract bargain-seeking customers and generate ancillary sales. For value-conscious shoppers, a sub-$100 price point places compact hybrid vacuums within reach of households seeking automated surface maintenance without investing in higher-end models that offer more advanced mapping or deeper cleaning capabilities.
HuffPost’s coverage emphasized that the Onoson is best suited for routine surface cleaning on hardwood, tile and low-pile rugs and that shoppers should temper expectations for heavy-duty stain removal. The outlet’s commerce team said it combines deal-tracking tools with consumer reviews to identify offers that are both genuine and useful to readers.
Walmart’s listing remains the point of sale for the current promotion. Shoppers interested in the Onoson model should note that electronics and home appliance deals can be time-limited and that inventory may be constrained during peak demand following media coverage.
