Stick to brands which offer support
I wouldn’t buy another Roborock product, we have had our revo for 18 months and it no longer mops, it won’t draw water from the clean water tank anymore, all Roborock do is offer advise and tips to get it working again, clearly there is a design fault. After allot of going backwards and forwards the machine has now been fixed under warranty, by a sub contracted repair company. I think its worth buying a Dyson in the future.
