A lot. On hardwood and tile, the Lefant M210 collects a surprising amount of dust and dog hair, even from floors that looked clean before it started. With no roller brush, hair goes straight into the bin instead of wrapping around anything, so pet homes get steady results day to day.

Sometimes. The M210 keeps no saved map, so it can loop over the same few spots and leave other areas untouched, and it wedges itself under low dressers, recliners and ottomans. Blocking off low furniture before a run saves a lot of rescues.

Yes. The M210 connects to the app easily and scheduling is simple. The app is basic, though, and shows no map of the house, so you pick modes and times, not rooms. If it won't connect, Lefant says to use the newer Lefant app, not the old Lefant Life app.

Every 2 to 3 days in a home with a pet. Emptying the M210's bin is easy, and the brushes and filters are simple to clean, though it's worth keeping spare brushes and filters on hand so a worn one doesn't hold up the next run.

Usually. The M210 heads home when its battery runs low, but a few units sometimes fail to find the dock on the first try and need a second attempt. Keeping the area around the dock clear gives it the easiest approach.

Up to 120 minutes, but Lefant measured that in low suction mode. Higher suction settings will run for less.

Yes, but Lefant says not to use zigzag mode on carpet. The other modes are random, spot, edge, scheduled and manual.
