Poor quality
I purchased a Roborock Q7 18 months ago. Paid over $600 for it. It stopped emptying into the vacuum bags a few months ago but I didn’t have time to look into repair until now. I was just advised their warranty expired after a year! I have had an eufy for 5 years and a roomba for nearly ten years- both are still working and I paid about $250 for them. Don’t purchase from this company - they don’t stand behind their products, which are of inferior quality.
