What is the difference between a window cleaning robot and a floor robot vacuum?
Window cleaning robots use suction to adhere to vertical smooth surfaces (glass, tile, mirrors) and navigate them automatically using microfiber pads and a water spray system. Floor robot vacuums operate on horizontal surfaces and use brushes and suction to collect dust and debris. Some floor robots also mop with a wet pad. The two categories serve entirely different cleaning needs — most households benefit from both.
Do window cleaning robots work on all types of glass?
Most window cleaning robots work best on smooth, flat glass surfaces — standard float glass, tempered glass, and mirrors. They typically do not work well on frosted, textured, or patterned glass because suction cannot maintain a secure hold. Tinted glass is generally fine. Always check the product specifications for surface compatibility before purchasing, especially if you have specialty glass in your home.
Is a robot vacuum with LiDAR mapping worth the extra cost?
For most homes, yes. LiDAR-equipped robots like the Liectroux X6 create an accurate map of your home and clean in efficient, systematic rows — covering every area without redundancy. Basic robots use random bounce navigation, which misses corners and takes longer. If you have a multi-room home or multiple floors, the time savings and thorough coverage justify the higher price. For a single small room, a basic model works fine.
