I use the grippa compact vac 2000watt, with either the section 10 carbon clamps pole or base sections of the modular turned upside down
Find this more than adaquet for power and there new crevice tools work well
I Use the smaller compact vac as it’s just lighter and easier when by myself it’s possibly little more expensive than some companies, but I like dealing with grippa
Would be interested when a company comes up with a vac hose that’s not ridged internal as they get so heavy when slurry sticks inside
