How to Choose a Robot Vacuum in India

The difference between a random-path robot and a LiDAR robot is not incremental. A random-path robot on a 1,000 sq ft flat will take ninety minutes and leave a third of the floor untouched, in a different third each run. A LiDAR robot maps the flat once, cleans it in rows in forty minutes, resumes where it left off after charging, and lets you say 'clean the kitchen'.

If the budget cannot reach a LiDAR model, a good cordless stick vacuum at the same price is a far better purchase than a cheap robot.

Almost every robot sold in India as a vacuum-mop drags a damp microfibre pad behind the vacuum unit. Water drips from a small tank onto the pad; the pad wipes. There is no downward pressure worth the name and no scrubbing.

That keeps a floor that is already clean looking clean, and it does so daily without you. It will not remove dried dal, a tea ring or a footprint of dried mud. Read the marketing accordingly.

The better implementations add something real: spinning pads with downward pressure, pads that lift when the robot crosses carpet, and docks that wash and dry the pad. The pad-lift feature is the one that matters most in Indian homes, because dragging a wet pad across a rug is how the rug gets ruined.

A robot's onboard bin holds 250-500 ml, which is one to three runs in a typical Indian home. Emptying it means opening a dust chamber indoors every other day — precisely the chore the robot was bought to remove.

A self-emptying dock holds two to twelve weeks of debris in a sealed bag. It costs ₹8,000-15,000 more and it is the single feature most correlated with people still running their robot a year later.

Premium docks add pad washing, hot-air pad drying and automatic water refill. The pad drying is not a luxury in humid coastal cities — a damp pad parked in a dock develops a smell within a day.

• 4,000-6,000 Pa — hard floors, no pets, light daily dust. Adequate and quiet.
• 6,000-10,000 Pa — hard floors with rugs, or one shedding pet.
• 10,000-18,000 Pa — medium pile carpet, multiple pets, or a home that collects a lot of street dust.
• 18,000 Pa and above — diminishing returns for most Indian homes; the noise increase is more noticeable than the cleaning improvement.
• An anti-tangle rubber brush matters more than raw suction if anyone in the house has long hair. Bristle brushes wrap and need cutting free weekly.

• Thresholds — most robots clear 15-20 mm. Older Indian homes often have 25-40 mm door sills that will confine the robot to one room.
• Dark floors — cliff sensors on some models read very dark tiles or dark rugs as a drop and refuse to cross them.
• Loose cotton rugs and dhurries — get sucked in and jam the brush. Roll them up or use no-go zones.
• Stairs and duplexes — a robot cannot climb. A duplex needs two robots or a robot plus a stick vacuum.
• Puja rooms, floor seating and clutter — robots need clear floor to be useful. A cluttered floor is a robot that stops every four minutes.
