Robot Vacuums / SwitchBot
SwitchBot S20 Floor Cleaning Robot
The Matter and Apple Home robot with real plumbing — noisy, and short on specs.
Overall score 7.1/10
Pros
- + Native Matter and Apple Home support — nothing else here can be driven from Apple's Home app without a bridge
- + Roller mop that scrubs and rinses itself during the run, at $700 less than the eufy Omni S2
- + A genuine plumbed auto-fill and drain path via the $139.99 Water Station, rather than a whole different SKU
- + TechRadar rated obstacle detection as excellent in real-world use
Cons
- − SwitchBot publishes neither a runtime figure nor a bin capacity — two of the specs that actually decide whether it finishes your floor
- − 4,000 mAh is the smallest battery among the omni-dock robots here
- − TechRadar found it noisy, erratic about docking, and unable to vacuum straight after mopping
- − 10,000 Pa is the lowest suction claim of the $700+ robots, and this one is chunky rather than slim
- − The plumbing kit is a $139.99 extra on top of an already $799.99 robot
SwitchBot S20 Floor Cleaning Robot review: what the specs say
The Matter and Apple Home robot with real plumbing — noisy, and short on specs. At $799.99, SwitchBot's 2025 model sits in the middle of the range — the robot Vacuums we compare run from $139.99 to $1,399.99. It scores 7.1/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Dock Automation at 8.5/10 — how much the dock genuinely does unattended: self-empty, hot-water mop wash, hot-air dry, solution dosing, plumbed refill and drain — minus the jobs it still leaves you.. The weakest is Value at 6.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: SwitchBot publishes neither a runtime figure nor a bin capacity — two of the specs that actually decide whether it finishes your floor; and 4,000 mAh is the smallest battery among the omni-dock robots here. Every specification on this page comes from SwitchBot's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.

Full Specifications
| Claimed Suction (Pa) | 10,000 Pa — a third of the eufy Omni S2's claim and under half the Narwal Flow's, at a comparable price. TechRadar's professional tester's whole argument is that past roughly 10,000 Pa the Pascal number stops predicting cleaning at all |
| Independent Test Result | TechRadar: strong mopping that does not spread spills, 'excellent object detection', but noisy and erratic about docking, and it cannot vacuum straight after mopping because the damp roller smears debris. MacRumors reviewed it as the budget Matter option. It does not appear in Vacuum Wars' 2026 Top 20 |
| Navigation & Obstacle Avoidance | LDS LiDAR SLAM plus an AI camera. TechRadar's tester saw it reliably avoid cables, shoes and other floor clutter |
| What the Maker Promises About Pet Waste | SwitchBot publishes no pet-waste avoidance guarantee |
| Mop System | RevoRoll roller mop with a continuous clean-water feed and an in-run scraper, 300 scrubs a minute at 1 kg of pressure, in Moist or Wet modes |
| Mop Lift Over Carpet | Auto-lifts the roller and cuts the water on carpet detection, but SwitchBot does not publish a lift height in millimetres anywhere on the US product page mm |
| Dock Type & Plumbing | Self-empty plus mop wash, dry, water refill and dirty-water drain. The Auto-Fill & Drain version is the same $799.99 but needs the separate S Series Water Station at $139.99 to reach your plumbing — the only genuinely plumbed option here that is sold as an add-on box |
| Dock Mop Wash & Dry | Washes the roller and dries it with 122°F (50°C) warm air. TechRadar warns the auto-empty cycle is loud |
| Dock Bags & Running Cost | Proprietary bag; SwitchBot rates the dock at 90 days between changes, so about four bags a year. The roller mop and the filter are the other recurring parts. Add $139.99 once if you want the plumbed water station |
| Robot Bin Capacity | Not published by SwitchBot on the US product page ml |
| Rated Runtime (and at what setting) | Not published by SwitchBot as a minute figure. The battery is 4,000 mAh — the smallest of the omni-dock robots here, against 6,400 mAh for the Roborock, Dreame and ECOVACS flagships — and charges in under four hours min |
| Account, Cloud & Camera Privacy | A SwitchBot account is required for the app, but because the robot is a Matter device Apple Home, Alexa and Google can start and stop it locally without one — the best cloud-independence story on this page. There is an AI camera on board and SwitchBot publishes no statement about where the frames are processed |
| Connectivity | Wi-Fi (SwitchBot app), Matter, Apple Home, Alexa, Google Home |
| Material | Plastic; SwitchBot publishes no housing material |
| Warranty | 12 months |
