New Karcher B 50 W Bp R55 22" Cylindrical Traction Drive Floor Scrubber
Our Take (from the SES Sales Team)
“The B 50 W Bp R55 is a full-size walk-behind scrubber for warehouses, factories, schools, retail floors and other large hard-surface areas where a compact machine runs out of tank. It cleans a 22 in path with a cylindrical roller brush, carries 13.2 gal of solution and recovery, and wheel drive moves it at up to 3.7 mph, so the operator steers instead of pushing a 427 lb machine.
What stands out is the R55 head on textured and dirty floors. The roller brush pre-sweeps coarse debris into a small container as it scrubs, and the brush head and 33 in parabolic squeegee are die-cast aluminum, built to hold blade pressure through tight turns and on uneven surfaces. A yellow key limits operators to everyday settings, while a grey key gives supervisors the rest.
Two things to weigh. This is the AGM battery version, which Kärcher does not offer in California; a lithium-ion R55 is a separate model. And on smooth floors where water use matters most, the O51 orbital head is the alternative to look at.”
“Fantastic service and easy application and approval process. It only took a few minutes and our new floor scrubber was on its way.” — Mike T., Google review
