Surface-safety evidence is limited but positive, based on the soft roller’s gentle buffering action on hardwood.

Tool-change simplicity
Product 1: Dyson V15s Detect Submarine Wet...
3.9

Tool changes were usually quick and easy, but several reviewers disliked the extra reconfiguring needed because vacuuming and mopping require separate heads.

Product 2: Shark Vertex Pro Cordless Vacuum...
4.3

Tool changes and configuration changes were described as simple, especially lift-away transitions and snap-in cleaning parts.

Under-Furniture Pickup
Product 1: Dyson V15s Detect Submarine Wet...
4.5

Under-furniture pickup was praised in one review for the thin wand and flexible head joint.

Product 2: Shark Vertex Pro Cordless Vacuum...
4.4

Under-furniture cleaning is widely praised thanks to the MultiFLEX/flexible wand, though one reviewer disliked the feel and low-appliance reach is limited.

Upholstery / Above-Floor Pickup
Product 1: Dyson V15s Detect Submarine Wet...
4.5

Above-floor and upholstery pickup was praised, especially for sofa, dog-bed, mattress, shelf, and couch-corner use.

Product 2: Shark Vertex Pro Cordless Vacuum...
4.4

Above-floor and upholstery cleaning is generally good, helped by attachments, handheld conversion, and lift-away-style use.

Versatility
Product 1: Dyson V15s Detect Submarine Wet...
4.2

Versatility was a major strength because the machine combines high-end dry vacuuming with a mop head and broad attachment set.

Product 2: Shark Vertex Pro Cordless Vacuum...
4.7

Versatility is one of the strongest themes, with reviewers repeatedly praising multi-surface cleaning and multiple configurations.

Water tank
Product 1: Dyson V15s Detect Submarine Wet...
