D990 Robot Vacuum and Mop

Osoji sells the D990 as a Wi-Fi-connected floor-cleaning robot with interchangeable dry-vacuum and wet-mopping equipment. Its low circular chassis combines anti-collision and anti-fall sensors with smartphone control, a HEPA filter and an automatic charging dock. The product is intended for routine cleaning across flat domestic surfaces and beneath furniture, with the selected dust or water tank determining the operating mode.

The DUO D990 WiFi listing specifies suction up to 2,000 pascals and a 7.5-centimetre body height. Osoji's support library lists D990 WiFi separately from DUO 990, while the retail description also uses the Dojo DUO 990 name; this record follows the D990 identity in the product title. Mopping requires the water tank, pad and user maintenance, as the dock does not wash or exchange consumables.
