Eufy 30c max or 15c max

[JLbaby]

Can anyone tell me the difference between these two and does anyone have either and recommend one over the other? Does one have mapping and the other doesn’t? Is that a big deal?

From what I can see the only difference is the boundary strips on the 30c max? There’s only a £10 difference with a discount code at the moment but just trying to decide which one to go for.

Thanks!

The only difference IS the boundary strips.
I brought the 30 as it was cheaper than the 15 at the time.
The boundary strips aren't essential but I do use them, for £10 if probably get the 30.

I’ve got the 30 and I’ve yet to use the boundary strips DH thought it was a lockdown gimmick purchase but he loves him now (he’s called Steve) we have a lot of pets and he’s on everyday he does a great job on the hardwood floors downstairs just keeping them tidy. I only do a proper hoover once a week now.

Thanks! I’ve gone for the 15 max in the end as I know I won’t use the boundary strips.
