Later independent confirmation that the robot actually reached US shelves on that date was not found in subsequent coverage.
Bottom lineThe hardware features described, dual spray, edge-leakage sensing, vacuum suction adhesion, match manufacturer specifications; the broader comparative and launch-timing claims in the coverage remain sourced to the original announcement.
ImpactOn autonomy
- No new autonomy capability confirmed; edge-leakage sensing extends existing route detection
- Manufacturer describes AI-based route planning consistent with the prior HOBOT-298 model
On readiness
- US retail availability was announced but not independently confirmed as delivered on schedule
- Owner-facing reviews of the HOBOT-2S appeared in later 2021 and 2022 coverage

Announcement
Hobot Technology unveiled the HOBOT-2S in trade coverage published September 2, 2021, describing it as a successor to the HOBOT-298 with a US retail launch set for October 1, 2021.
Hardware Changes
Manufacturer listings describe dual ultrasonic spray nozzles operating at 108 kHz that mist water in three directions, left, right, and down, during a cleaning pass, an addition over the single-direction spray on the HOBOT-298. New Edge-Leakage Sensors are described as detecting seals and frameless window edges, and the robot adds app-configurable voice prompts and over-the-air firmware updates.
Adhesion and Safety
Manufacturer specifications list vacuum suction, not magnets, as the adhesion method, rated at 6.0 kg of suction force. A 150 kgf-rated safety rope ships as standard equipment, and a later reviewer noted the robot’s voice prompt reminds the user to tie the rope and clear the area below before a cleaning cycle starts. An embedded backup battery is documented to hold the unit in place for about 20 minutes during a power outage.
Launch Follow-Through
Robovations did not find independent coverage confirming the HOBOT-2S actually reached US retail on the announced October 1, 2021 date; reviewer coverage of the model appears from 2022 onward.
