Are robot vacuums really reliable? What are their common drawbacks?

My first experience with a robot vacuum was two years ago when I bought a certain domestic brand, lured by the low price—only to fall into a trap: **The biggest pain point was the cleaning dead zones.** The ads claimed no dead zones, but in reality, it couldn’t reach corners, under the bed, or beneath the sofa, so I ended up manually cleaning those spots with a handheld vacuum. Later, I realized the key was in the side brush design. The Japanese brand I’m using now has added long bristles and special rollers to the side brush, and the corner cleaning performance has improved significantly. I’d recommend watching user videos testing cleaning performance before buying—don’t just rely on specs. As for battery life, honestly, they’re all pretty similar. Both brands I’ve used need to return to the charging dock after about 2 hours, so for a house over 200 square meters, you’ll have to divide the area into zones—otherwise, it’s not enough. A tip is to buy one with a 3000mAh+ battery to avoid the awkwardness of it stopping mid-clean to recharge. For noise control, while silent models are indeed quiet, their cleaning power suffers. From my experience, anything under 65 decibels is acceptable for nighttime use—try it out in-store before buying.
