Yep, those are nice as they can double as a power-outage monitor too. I wish they were a bit more svelte in form, but so it goes. Excellent driver for them here.
It looks like the biggest difference is the Q8max+ has stronger suction. I guess that would be a YMMV thing. We have all hardwood or luxury vinyl tile so the suction on the Q7Max+ is fine for us. If you have carpeting, I could see where the stronger suction may be a bonus. Overall, I've been pretty happy with my Q7 max+.
Thats actually good to know. we have several they we haven't had down because of the not house broken fosters we've had. but we are going t put them back down now that they will all be gone.
We pulled ours from the washer the other day (it's one of the thick ones). Dried it then put it down..... Farking GSD walks in and tracks mud all over it while our backs were turned...sigh... Back to the washing machine...
