I have the following machine cleaners.
1. Electrolux bagless wired vacuum at $499 >5 years back. Found it too cumbersome to use and suction power was so so. I had a soft spot for this brand as my parent’s time used their stuff and lasted a long time.

2. Karcher stream cleaner sc4 bought $1099 during mco. This was before their steam mop was launched. Used it for a while but the handle would get hot and sometimes get a bit of steam on myself which was uncomfortable. So use with caution. I think it’s good for fabric cleaning such as mattress, sofas, carpets and curtains. Or for cleaning toilets. Too messy for regular cleaning.

3. Dyson v12 >$3k last year. The best so far out of my machine cleaners. I used it almost daily. Quite light, with power on button, good suction and cordless. I do less mopping after using the Dyson.

If you are looking at Dyson, you can look at previous models which are cheaper such as the v8 absolute or v11 absolute.

Hope this helps.
