if the surface is carpeted, just vacuum it manually, the robots can't handle carpet very well

we've had good luck with the eufy ones but you HAVE to empty them every time you run, you HAVE to run them every day and you HAVE to perform periodic maintenance. current one is going strong for 2 years

i like the eufys because they don't store the interior mapping data for the company to package and resell which is what roombas actually exist to do
