SwitchBot S10 and External Water Tank review: No pluming required

The SwitchBot S10 has been a pleasure to have running across our floors. It cleans as well as the best robot vacuums on the market, running autonomously for weeks on end. 6,500Pa of suction pressure picks up any dust, crumbs, or debris from your hard floors and carpets. Smart home integration is at its best with this bot, and we are fans of the water delivery system, which is a separate station that fits under your cupboards and can be plumbed directly into your house plumbing for completely autonomous operation.

The Auto-Empty & Drying Station is both a dust collection station and the charger for the S10 robot. This is where the bot will live when not in use. The Auto-Fill & Drain Water Station is only used when needed, and can be placed in a discrete location of the home, just as long as the hoses can reach your home plumbing.

For those that cannot commit to fully installing the S10 water station, the brand new External Water Tank is what makes the difference. The S10 is finally a viable solution for all users! The water tank simply slides over top of the water station, connect the hoses, manually fill the clean water reservoir, and off you go.

There is only one thing I would ask you to consider with this cleaning bot: it’s large. At 14.37 inches in diameter, it is over an inch wider than many other units, which makes it one inch too wide to fit between our chair legs to clean under the table. Likewise, at 4.53 inches tall, it’s over an inch taller than others and just a half-inch too tall to fit under our cabinets and table leg supports. This size is an advantage in open spaces, so consider your needs before purchasing.

SwitchBot also kindly sent me their new Water Leak Detector smart home sensor. This is not provided in the base kit, but I’m sure glad I had it. When I connected the water tank to the water fill station, I accidently didn’t connect the clean water hose properly. Thankfully, I had placed the sensor right there and it immediately alerted me. Take the time to connect your station properly, but, do consider a water detection sensor of your own.

For those in the SwitchBot ecosystem, the S10 and water station can be configured to automatically fill your humidifier or drain your dehumidifier.

In the end, the SwitchBot S10 is a reliable and capable floor cleaning solution that I can happily recommend for your home.

The SwitchBot S10 launched in 2023 as an early offering for robot vacuums that could mop and be plumbed into the house. Integration with the SwitchBot smart home ecosystem is a bonus over the competition, and the new External Water Tank system makes this bot viable for any home.
