iRobot Roomba Plus 405 Combo – Plus.Parts® Maintenance Set

The iRobot Roomba Plus 405 Combo is the entry point into the Plus Combo line: around 7,000 Pa of suction, two counter-rotating microfibre pads spinning at 200 RPM, ClearView LiDAR navigation without a forward camera, and an AutoWash dock that auto-empties the bin for up to 75 days, washes the pads between runs and air-dries them. Because it air-dries rather than heat-dries, the pads return to the robot slightly damp.

This set covers the full service scope with Plus.Parts® direct-fit alternatives to the original iRobot parts: two Multi-Surface Rubber main brushes, four Edge-Sweeping side brushes, six high-efficiency filters, six AutoWash dock dustbags and six DualClean mop pads – 24 parts in all. The air-dry cycle is the detail that shapes maintenance here: a pad stored damp grows odour faster than a heat-dried one, so rinse the pads regularly and rotate between the installed pair and a spare set so one pair can fully air-dry outside the dock. Inspect the pads at the six-to-eight-week mark for matted fibre or stiffness and replace when either appears, trending toward eight weeks rather than ten.

Tap the high-efficiency filter firmly on all four sides every one to two weeks and keep it dry – water degrades the medium even when the filter still looks intact – then replace it every four to six months at this suction tier. Clear the Multi-Surface Rubber main brush and both end caps weekly, freeing the bearing holes with a toothpick, and replace it every six to twelve months. Replace the Edge-Sweeping side brush every three to six months, since splayed bristles sweep debris sideways along the wall instead of into the brush path. The dock bag is rated up to 75 days; wipe the bin port and the dock suction collar monthly so a dust film does not break the seal and trigger an early bag-full alert. Wipe the ClearView LiDAR window weekly. Behind the set is a real team at VacuumReviews.eu, so if pads come back damp or streaks appear along the skirting, reach out and we will help you sort it.
