Hi-Low Solutions designed the BEAST to make large surfaces clean faster and easier with less effort and labor. It has 4ft, 5ft, 6ft and 7ft Surface Cleaner interchangeable attachments to clean large surfaces. We’ve cleaned a 7000 square-foot driveway while training doing it twice in 30 minutes.(did it twice for training purposes) The front loader has attachments to clean 2 different types of street gutters and curbs. Companies have done 65k sqft parking garages in 1 day with 1 employee & another company did a 600k sqft parking garages in 3 days . They have been able to do 2 miles of street gutters and curbs in a day. The same crew did 1/4 of mile or less with 3 guys doing it by hand. If you have large surfaces, The BEAST is a no brainer.
