ONSON

ONSON, founded in Shenzhen in 2015, took a dual-product approach by developing both cordless and robot vacuums. This breadth of engineering expertise shows in their robot models, which include HEPA filtration to capture fine dust particles, edge-cleaning brushes, and multi-stage suction systems. The company positions itself as focusing on air quality alongside cleaning performance, which appeals to allergy-prone households.

For thick carpet, ONSON's multi-stage suction design provides adequate power without being top-tier. The HEPA filtration makes it particularly attractive if anyone in your home has allergies or asthma. ONSON's robots won't be the fastest or most intelligent on the market, but they provide reliable performance at a reasonable price point with added filtration benefits.
