The thinnest LiDAR robot Concept makes, designed to slip under beds and sofas that taller robots simply cannot reach.
We measured the VR3300 at exactly 7.6 cm at its tallest point, and it slid under a standard IKEA Kallax shelf with room to spare -- something no other LiDAR robot in our lineup managed. Pair the slim profile with a sub-$175 price and you have the cheapest LiDAR-mapped robot we have tracked -- a category where the next competitor starts around $200. The catch is that Concept squeezed the internals hard to hit this profile: the 210 ml dustbin fills in a single session if you have pets, and 3,000 Pa of suction means anything thicker than low-pile carpet is essentially decorative. Think of it as a daily maintenance bot for apartments with beds and couches you never want to vacuum under manually again.

Pros & Cons
What We Like
- + Only 7.6 cm tall with an internal laser — clears low furniture most LiDAR robots cannot
- + Combined LiDAR and TOF sensors give surprisingly precise mapping for the price
- + Automatic carpet detection boosts suction to max, then dials back on hard floors
What Could Be Better
- − 3,000 Pa suction is the weakest in the lineup — carpets over low pile are a stretch
- − Tiny 210 ml dustbin fills up fast in homes with pets or high-traffic areas
