This actually saves you money. Because the 4-week rate is heavily discounted, it’s less expensive to rent a machine at the 4-week rate than three times the one week rate. Here’s an example… The weekly rate for the 20″ scrubber is $465. Three times $465 is $1,395. The 4-week rate for the 20″ scrubber is $1,170, so you save $255 by getting a 4-week rental. You can still return the machine after 3 weeks. Just call our customer service department at (833) 736-8677 to schedule your return whenever you’re done.
