Buyer Questions
Are robot vacuums worth buying?
For maintenance cleaning between full vacuums, absolutely — running a robot vacuum daily keeps floors noticeably cleaner and saves 2–3 hours of vacuuming per week.
Do robot vacuums work on thick carpets?
Most robot vacuums handle low-pile and medium-pile carpet well; high-pile shag carpets can tangle the brush roll. Check the manufacturer's pile height specification.
What's the battery life on a robot vacuum?
Most run 60–120 minutes per charge; higher-end models (Roborock, Roomba j-series) automatically return to charge and resume cleaning where they left off.
How often should I clean the robot vacuum brush roll?
Weekly for homes with pets or long-hair residents; monthly for others. Tangled hair is the most common cause of suction loss and motor wear.
