eufy BoostIQ RoboVac 11S (Slim) Robot Vacuum
The no-frills entry point. No app, no mapping, no mop — just a super-thin robot that self-charges, boosts suction automatically on carpet, and cleans the tight spots under furniture other robots cannot reach.
Our review
The 11S is for buyers who want a robot vacuum to just handle daily dust and crumbs without an app, an account, or a learning curve. It runs from the included remote or the buttons on top, self-charges when the battery runs low, and its main structural advantage — a genuinely slim body — lets it clean under sofas, beds, and low cabinets that trip up thicker robots.
BoostIQ automatically increases suction the moment it detects carpet and eases off on hard floors to conserve the battery, which is the one piece of "smart" behavior on an otherwise simple machine. There is no mapping, no room-by-room scheduling, and no mop, so treat this as a budget daily-maintenance robot rather than a full replacement for a stick vacuum — it earns its place by being cheap, quiet, and genuinely thin.

Frequently asked questions
Does the 11S have an app or Wi-Fi?
No — this model is controlled with the included remote and the buttons on top. If you want app control, scheduling, or mapping, you will need a step-up model like the ones elsewhere on this list.
Will it fit under my sofa or low cabinets?
That is its main selling point — a super-thin body designed to fit under furniture that stops bulkier robots, so it can clean areas other vacuums simply skip.
How does it handle carpet vs hard floors?
BoostIQ automatically increases suction power when it senses carpet, then returns to normal power on hard floors to save battery — you do not need to switch a mode yourself.
