Dyson DC15chat_bubble_outlineFrom real comments

Owners consistently report outstanding long-term durability. Multiple commenters describe using the same DC15 for 15, 17, or over 20 years with only minor part replacements like the hose or on-switch. One called it their best purchase ever, another said it was still going strong after a daughter found it discarded on the street. Even units bought secondhand or salvaged for cheap proved nearly indestructible, with one owner unable to 'kill it' after three years of construction cleanup use.

Suction and cleaning performance impress across carpet types. Several reviewers highlight strong suction and effective cleaning on carpets, including thick pile, describing it as an excellent daily driver. One noted the head jumps on the backward pass over super thick carpet, a minor complaint. Others praised how much dirt it picked up even in old, dusty units, and one commenter noted the sound was healthy, quiet, and pleasant during use.

Maintenance and filter design draw the most criticism and confusion. Many comments focus on difficulty removing and cleaning the lower HEPA filter, brushbar motor housing reassembly, and hose disconnection, with some calling instructional videos unhelpful. The 'lifetime' HEPA filter is not washable and can clog, which several felt contradicted Dyson's 'no filters to clog' claims. Additional gripes include gearbox hair buildup, rusted brush motors, missing gaskets on replacement filters, and heavy, bulky handling likened to a 'space station.'
