The Kärcher K5 Premium is the premium European-engineered pressure washer for Canadian buyers who want the best build quality and a connected home system — it includes Kärcher's Home & Garden app for customized cleaning programs, a water-cooled motor for longer runtimes, and 2000 PSI with 1.4 GPM that handles every common household cleaning task. Kärcher is the global pressure washer standard for a reason.
“"This my third purchase. The last one also a K5 lasted over 10 years, until the motor stopped working. Karcher makes quality pressure washer with great features and useful attachments."”
